# Manage MCP servers via the JFrog Agent Guard
Install, list, and remove MCP servers. When Agent Guard is on (see Step 0),
do that only through the Agent Guard — ignore other install commands from an
MCP's docs.
On a non-zero Agent Guard exit, classify stderr per
[key-rules](references/key-rules-and-troubleshooting.md#classify-npx-jfrogagent-guard-failures)
— do not treat a bare `404` as “MCP missing.” If Agent Guard is enabled, a
**hard stop** means: do not fall back to the usual MCP install routes that skip
the approved catalog and Agent Guard as the MCP proxy.
In code examples below, `<skill_path>` refers to this skill's directory and is
resolved automatically by the agent. If the agent does not resolve it, determine
the path by locating this SKILL.md file and using its parent directory.
## Runtime requirement
Node.js 18+ on PATH — `node` runs the Step 0 check, `npx` runs
`@jfrog/agent-guard`. On an older runtime the Step 0 check exits with
`Unknown: requires Node.js 18 or newer`.
## Shell quoting rule
**Always double-quote every interpolated value in shell commands.**
`<REGISTRY_URL>`, `<SERVER_ID>`, `<JFROG_PROJECT_KEY>`, `<MCP_NAME>`,
`<spec.packageName>`, and any other substituted value must be wrapped in
`"..."` when passed on a command line. Unquoted values let shell
metacharacters (`;`, `|`, `$()`, etc.) execute before `npx` runs.
## Step 0: Agent Guard activation (silent, mandatory)
Before anything else, run this check and WAIT for its exit code. Do not narrate
it. Do not reuse a result from an earlier turn in this session.
```bash
node "<skill_path>/scripts/jfrog-agent-guard-check.mjs"
```
Request network access for this command.
**This script only:** optional positional `<SERVER_ID>` = a `jf` config
server id (e.g. from `jf config show`). Nothing else.
- NEVER pass `--server`, `--project`, `--mcp`, or any other flags to this
script.
- NEVER pass an MCP package name (e.g. `kubernetes-mcp-server`,
`@scope/pkg`).
- NEVER pass a URL (`https://…`).
- NEVER derive `<SERVER_ID>` by parsing a hostname out of `JFROG_URL` /
`JF_URL` (e.g. taking `myco.jfrog.io` from
`JFROG_URL=https://myco.jfrog.io`). If `jf config show` legitimately
names a server `myco.jfrog.io`, that is fine — the ban is on deriving
the id from the URL, not on hostname-shaped values from `jf config`
itself.
- Substitute the real jf server id for `<SERVER_ID>` — never a literal
`[...]` or `<SERVER_ID>`. Any unsupported or unknown argument stops
the gate (`Unknown: …`); it is NOT silently ignored and does NOT
fall back to env credentials or the default `jf` server. In a
multi-JPD setup that fallback would report the wrong platform.
Pass `<SERVER_ID>` when it is already known from context (an existing Agent
Guard MCP entry's `--server` value, or one the user named) so the gate checks
the JPD you will actually target, not the CLI default — this matters only in
multi-JPD setups. Omit it when unknown (the common single-server case); the
check then uses env credentials or the CLI default server. Do NOT invent a
server id from the MCP name or from `JF_URL`. Do NOT block on resolving a
server just to run this gate.
```bash
# Only when certain of the JFrog platform server id:
node "<skill_path>/scripts/jfrog-agent-guard-check.mjs" "<SERVER_ID>"
```
If the first run fails with a network error, timeout, or other spurious issue
(sandbox, DNS, HTTP 5xx), run the same command again with network access and use
that second exit code. In a sandboxed harness (e.g. Cursor, Codex) such a
failure is often the sandbox's network allowlist, not a real outage — check your
`harness-<agent>.md` reference for a sandbox/allowlist fix. Do not retry when the
reason is missing credentials or missing jf config.
Interpret the exit code:
### Exit 0 — Agent Guard enabled
This organization uses Agent Guard. Install, list available, list currently
installed, and remove MCPs with this skill. No other approved path for those.
### Exit 2 — Agent Guard disabled
This organization does not use Agent Guard. Honor that. Do not mention Agent
Guard or this check unless asked. Do not tell the user to contact an admin or
enable a registry.
- **Install** and **List → Available to install:** ignore those sections. Serve
those asks as you would if this skill had never loaded.
- **List → Currently installed** and **Remove:** proceed (local config only).
Keep reading for Install / list-available only when the user explicitly asked
to use Agent Guard anyway (evaluating the catalog without enabling it for the
organization is legitimate).
### Exit 3 — Multiple JFrog servers, none set as default
The gate could not tell which JPD to check: no complete `JFROG_URL`/`JF_URL` +
`JFROG_ACCESS_TOKEN`/`JF_ACCESS_TOKEN` credential pair is set in the env,
there is no default `jf` server, and two or more servers are configured.
This is NOT a disabled or unknown result — the gate just needs the user to say which server to use.
Do this:
1. Show the user the server ids from the gate's `AmbiguousServer:` line (they
match `jf config show`) and let the user manually select one.
2. Re-run Step 0 with the selected id as the `<SERVER_ID>` argument and act on
that exit code. Exit 0 or Exit 2 → follow that section. Any other non-zero
means the id is not a configured `jf` server (a typo) or was unreachable —
tell the user it did not resolve and have them pick a valid one (or stop); do
NOT fall through to "status unknown", which would bypass Agent Guard.
Wait for the user's selection before continuing; the gate stays ambiguous until
they choose.
This selection is not relevant for **List → Currently installed** and **Remove**,
which touch local config only — handle those normally, with no server selection.
### Any other non-zero exit — status unknown
The check did not reach a definitive platform answer (no credentials, timeout,
HTTP error, network/DNS). Treat it like Exit 2 for Install and List → Available
to install (ignore those sections; keep serving the user). List → Currently
installed and Remove still proceed. (Exit 3 is handled above, not here.)
Mention once — as a side note while continuing — what failed and that the user
can use the `jfrog-init` command to fix any local configuration issues. Do not
ask them to decide, do not repeat it, and do not stop to fix it.
## Harness config
**Harness config (resolve once, up front).** Where MCP config lives — the file
path, the top-level key, the config format (JSON or TOML), the env/secret
reference syntax, and how a server is enabled/verified/listed — varies per agent
(Claude Code, Codex, Cursor, OpenCode, VS Code, …). Those values are NOT
hard-coded in this skill. Read
[references/harness-common.md](references/harness-common.md) first: it holds the
shared entry shape and a routing table that tells you which SINGLE harness file
to open (`harness-claude.md`, `harness-codex.md`, `harness-cursor.md`,
`harness-opencode.md`, `harness-vscode.md`, …).
**Read common + exactly one harness file — do NOT open the others.** Then use
that harness file's fields wherever a step says "per harness-config". Adding a
new agent is a new `harness-<name>.md` file, with no change to this workflow.
Never hard-code one harness's `.mcp.json` / `mcpServers` / `claude mcp list`
values into your actions.
## Prerequisites
**Read the base [`../jfrog/SKILL.md`](../jfrog/SKILL.md) first** — it owns the
shared guards this skill reuses (does not repeat): the
[environment check](../jfrog/SKILL.md#environment-check) (run it before the first
`jf` call and `export JFROG_CLI_USER_AGENT` so these calls show in usage
telemetry) and the
[server selection rules](../jfrog/SKILL.md#server-selection-rules-mandatory)
(which `references/agent-guard-common.md` builds on, not replaces).
## Pre-flight (Install and List → Available to install only)
Read [references/agent-guard-common.md](references/agent-guard-common.md) for the
canonical invocation (`npx --yes --registry "<REGISTRY_URL>" @jfrog/agent-guard`),
the `<REGISTRY_URL>` substitution, and the rules for resolving
`<JFROG_PROJECT_KEY>` and `<SERVER_ID>`. Removal and List → Currently installed
read only local config, so they skip this.
**Route the request**, then jump to the matching section:
| User intent | Section |
| --- | --- |
| add / install / set up / enable / configure an MCP | [Install](#install-an-mcp) |
| list / show / what can I install / allowed / approved / available / catalog / what's set up / connected in the context of MCPs | [List](#list-mcps) |
| remove / uninstall / delete / disconnect / turn off an MCP | [Remove](#remove-an-mcp) |
---
# Install an MCP
If Step 0 was exit 2 (or unknown treated as exit 2), ignore this section.
Continue serving the user without Agent Guard.
**Did the user name a specific MCP package?** ("add `foo-mcp`", "install
`@scope/bar`"). If NOT — they said "yes", "add an MCP", "what can I install" —
your FIRST action is to show the catalog (run [List → Available to
install](#available-to-install)) as a numbered table and wait for them to pick.
NEVER ask "which package would you like?" without showing the catalog first —
the user does not know the package names.
Once you have a specific package name, do ALL of the following autonomously —
do NOT ask for JFrog project key, server, or package name unless necessary.
## Step 1: Determine JFrog project key, server, and target config file
**Server ID and JFrog project key** — resolve both per the Pre-flight rules in
[references/agent-guard-common.md](references/agent-guard-common.md). Pass
`--server <ID>` in every Agent Guard invocation whenever the ID came from an
existing Agent Guard MCP entry or jf config; omit `--server` only on the
URL+token env path (`JFROG_URL`+`JFROG_ACCESS_TOKEN`, or legacy
`JF_URL`+`JF_ACCESS_TOKEN`). NEVER guess or assume `default` for the project key.
**Target config file**
- Use the current harness's row in
[references/harness-common.md](references/harness-common.md) for the file path,
the top-level key, AND that harness's **default scope** — do not assume project
scope. Most harnesses default to the project-level file (Claude Code
`.mcp.json`, Cursor `.cursor/mcp.json`), but **VS Code, Codex, and OpenCode
default to the user-level file** (VS Code `mcp.json`, Codex
`~/.codex/config.toml`, OpenCode `~/.config/opencode/opencode.json`) and treat
their project file (`.vscode/mcp.json`, trusted `.codex/config.toml`, project
`opencode.json`) as the opt-in scope. Follow the "Config files" row in the
harness file, not a fixed default here.
Create the target file if missing, using that harness's top-level key (e.g.
`{ "mcpServers": {} }`, or `{ "servers": {} }` for VS Code).
- Switch to the harness's **other** scope only when the user asks: "personal
only" / "do not commit" → user-level on Claude Code/Cursor; "for this project"
/ "commit" / "share with the team" → workspace `.vscode/mcp.json` on VS Code
(project `opencode.json` on OpenCode, trusted `.codex/config.toml` on Codex).
Respect any per-file note in the reference (e.g. Claude Code user scope is
`~/.claude.json`, NOT `projects.<path>.mcpServers`).
- Do not ask which scope unless the user brings it up.
## Step 2: Inspect the MCP in the catalog
Step 2 needs a specific MCP name. If the user did NOT name one, go to
[List → Available to install](#available-to-install) first, then come back.
Once you have a name, run a SINGLE command — no Fetch/WebFetch, no custom
curl/Python, no direct JFrog API calls:
```
npx --yes \
--registry "<REGISTRY_URL>" \
@jfrog/agent-guard \
--inspect \
--server "<SERVER_ID>" \
--project "<JFROG_PROJECT_KEY>" \
--mcp "<MCP_NAME>"
```
(never omit `--registry`; URL in [agent-guard-common](references/agent-guard-common.md))
**`--server` is conditional** — include it per the Step 1 rule (from an
existing Agent Guard MCP entry or jf config; omit only on the URL+token env
path — `JFROG_URL`+`JFROG_ACCESS_TOKEN`, or legacy `JF_URL`+`JF_ACCESS_TOKEN`).
Same rule applies to `--login` and the config entry below.
From the output JSON, extract (keep BOTH required AND optional):
- `spec.packageName` — exact package name for the config.
- Inputs to configure: for local MCPs
`spec.mcpServerType.local.bootParams.environmentVariables[]`; for remote MCPs
`spec.mcpServerType.remote.endpoints[].headers[]` (via `mcpInput.mcpInputDetails`).
Each carries `name`, `description`, `isRequired`, `isSecret`.
- `routing` — an OPTIONAL **top-level** field, never nested inside another
object. Read `routing.target` and `routing.url`, and keep both for the route
resolution below: they are two of its three conditions, never the route
itself. **Anything other than `"gateway"`** in `target` — absent field,
absent object included — is the **Agent Guard route** on its own.
Never treat the mere presence of the object as an answer — read `target`.
The agent guard is the only source of truth for this block: never validate
its shape here, and never enumerate the cases it covers. Both the absent and
the non-`gateway` cases are normal and mean nothing is wrong: never ask about
them, and never work out the route any other way.
**Resolve the route ONCE, here.** Steps 3, 4, 4a and 5 all read this single
answer and never re-derive it from `routing.target` alone. The **Gateway
route** is taken only when ALL THREE hold:
1. `routing.target` is `"gateway"`;
2. `routing.url` is non-empty;
3. your one harness file (Step 1) defines a **Gateway entry shape** — if that
file has no such section, this harness cannot express a Gateway entry.
Conditions 1 and 2 are `--inspect`'s answer and are never second-guessed;
condition 3 is only whether this harness can express it. Any one missing →
**Agent Guard route**: the stdio entry, with Steps 3, 4, 4a and 5 running
exactly as they do today — inputs planned, collected and exported like any
other Agent Guard install.
Test them in any order: condition 3 is a property of your harness file, not of
the `--inspect` output, so it holds or fails the same whether you read it
before or after. A `"gateway"` target **with** a non-empty `url` on a harness
whose file defines no Gateway entry shape therefore fails the gate — write the
ordinary `npx --yes ... @jfrog/agent-guard` stdio entry, never a remote one.
**A shape change needs a removal first.** If an entry with this exact
`spec.packageName` already exists in the target config file — exact key match
only, never a similar, partial, or guessed name — and it is not the shape you
are about to add (one case: it runs `@jfrog/agent-guard` and you are adding the
Gateway entry; the other case: it carries a `url` and no `command` and you are
adding the Agent Guard entry), add nothing: tell the user that entry exists and
that they must remove it before adding again. Never edit, merge, or overwrite
it, and never remove it yourself. Every other case is unchanged.
On non-zero exit, show the error verbatim, then classify per
[key-rules](references/key-rules-and-troubleshooting.md#classify-npx-jfrogagent-guard-failures).
Do not fall back to the usual MCP install routes that skip the approved catalog
and Agent Guard as the MCP proxy.
## Step 3: Plan inputs
`env` values are literals or value references in the harness's syntax (see
[references/harness-common.md](references/harness-common.md)). No secret is ever
entered in chat.
**Gateway route (as resolved in Step 2) — skip this step entirely.** The
Gateway holds the upstream credential, so no header or env input is written
into the entry and there is nothing for the user to provide.
Do NOT ask the user about optional inputs, and do NOT write an `env` block.
On the Agent Guard route — every case that is not the Gateway route, including
a `routing.target: "gateway"` this harness cannot express or an empty
`routing.url` — split Step 2 inputs by `isRequired`:
1. **Required** — always include in Step 4.
2. **Optional** — if even ONE exists, STOP and ask. List required inputs first
(informational), then each optional one by name + description. Do NOT decide
for the user.
3. No inputs → skip this step.
Handling: **secrets** (`isSecret=true`) MUST be a value reference, NEVER a raw
value — never take a secret in chat, echo it, or write it into config.
**Non-secrets** may be a literal or a reference. For the exact syntax and, on
shell-based harnesses (Claude Code, Cursor, Codex, Devin, Kiro, OpenCode), how the
user exports/persists the variable, see the harness file and
[references/persisting-env-vars.md](references/persisting-env-vars.md). (VS Code
prompts for `inputs` values on first start — no shell export.)
## Step 4: Write the config entry
**Write exactly ONE entry** — the Agent Guard entry, or your harness file's
Gateway entry shape on the Gateway route as resolved in Step 2
(`routing.target: "gateway"` + non-empty `routing.url` + that shape existing).
Write the Agent Guard entry into the target config from Step 1, following
[references/harness-common.md](references/harness-common.md) for the **shared
entry shape** (`type: stdio`, `command`/`args`/`_JF_ARGS`). Use your one
harness file only for path, top-level key, value-reference syntax, and any
"Full entry shape" override (Codex/OpenCode). Do not invent a different
`args`/`env` layout. This is the Agent Guard entry — or your harness file's
Gateway entry shape, on the Gateway route as resolved in Step 2.
**Config vs CLI (do not mix):**
- Config entry: project + MCP go in `env._JF_ARGS` as
`project=<JFROG_PROJECT_KEY>&mcp=<spec.packageName>`.
- Catalog CLI (`--inspect` / `--list-available` / `--login`): use `--project`
and `--mcp` as flags — those flags must **not** appear in the config
entry's `args`.
Guardrails (identical everywhere):
- `--yes` and `--registry <URL>` MUST precede `@jfrog/agent-guard` in `args`
(else npx hits the default registry → 404 / no-TTY hang).
- `"type": "stdio"` only — never `"http"`, `"sse"`, or a top-level `"url"` —
**unless** your harness file defines a **Gateway entry shape** AND Step 2's
`--inspect` output carried `routing.target: "gateway"` with a non-empty
`routing.url`. Then write that shape, with `url` copied verbatim from
`routing.url`. Anything else → the stdio rule applies with no exception.
Never write that shape because a URL looks like a Gateway URL, and never
build that URL yourself.
These are the same three conditions resolved in Step 2 —
restated here, never a second, looser test.
- `--server` in `args` is conditional (Step 1): drop it only on the URL+token
env path (`JFROG_URL`+`JFROG_ACCESS_TOKEN`, or legacy
`JF_URL`+`JF_ACCESS_TOKEN`). When present, its value is a jf config server
id — never an MCP name or a hostname from `JF_URL`.
- NEVER put `--project` or `--mcp` in config `args`.
- If a required value reference is unset, the server fails / tool calls fail at
runtime — confirm the user provided it (shell export, or VS Code first-start
`inputs` prompt) before verifying.
## Step 4a: Enable and verify the entry (mandatory)
Enable the entry per the current harness's **How to enable** row in
[references/harness-common.md](references/harness-common.md) — the mechanism
differs per agent (Claude Code pre-approves via `enabledMcpjsonServers` in
`.claude/settings.local.json`; Cursor/VS Code discover the file and enable via
their MCP UI). If a pre-approval write fails, continue — the user approves on
relaunch.
Then tell the user:
1. Provide every value reference from the entry — export it in the launching
shell (Claude Code, Cursor, Kiro, Devin, Codex, OpenCode — see
[references/persisting-env-vars.md](references/persisting-env-vars.md)), or
supply it at the first-start `inputs` prompt (VS Code). Unset values cause
warnings and runtime failures. When Step 4 wrote a **Gateway entry** there
is nothing to export — that entry has no `env` and no value reference. (A
stdio Agent Guard entry always follows this instruction, whatever
`routing.target` said.) Tell the user
instead that they will be asked to sign in to JFrog the first time the
server is used, and go straight to the restart.
2. Restart per the harness's **Restart** column.
3. Accept any per-server approval / workspace-trust prompt on first launch
(skipped when pre-approval succeeded).
4. Verify per the harness's **Verify**. Success = **at least one
upstream tool** you can see or call. If you already can, stop — do
not ask the user to check a tool count. If you cannot, Enable /
Restart may still be needed (tools often attach only after). An
empty tool list is not success and not a diagnosis — follow
[Connected but 0 tools](references/key-rules-and-troubleshooting.md#connected-but-0-tools).
Do not invent another debug path until that section is finished.
## Step 5: Authenticate OAuth MCPs (auto, after Step 4)
Skip this step entirely when Step 4 wrote a Gateway entry: OAuth runs between
the harness and the Gateway on first use, so a locally cached upstream token
would be read by nothing.
Otherwise run ONLY for OAuth-style remote MCPs — `--inspect` showed a `remote`
section with `type: "http"` AND Step 4 wrote no static auth header into `env`.
Skip for local MCPs and for remote MCPs whose auth comes from a static token in
`env`.
`--login` opens the browser, runs OAuth, caches tokens in
`~/.jfrog/jfrogmcp.conf.json`. Agent Guard may also expose
`enable_<slug>_tools` until login completes; invoking it starts the same
OAuth login from the session.
In the same turn, tell the user you are about to open the browser to sign
them in to `<MCP_NAME>` and immediately run the command — do not wait for
confirmation or a follow-up prompt:
```
npx --yes \
--registry "<REGISTRY_URL>" \
@jfrog/agent-guard \
--login \
--server "<SERVER_ID>" \
--project "<JFROG_PROJECT_KEY>" \
--mcp "<spec.packageName>"
```
Outcomes:
- **Exit 0** — OAuth completed; tokens cached; server ready.
- **`expected 401, got 200`** — MCP is anonymous (no auth needed); ignore
(even if the process exit is non-zero). Do not run the unmatched hard-stop.
- **Non-zero** — classify per
[key-rules](references/key-rules-and-troubleshooting.md#classify-npx-jfrogagent-guard-failures).
Do not fall back to the usual MCP install routes that skip the approved
catalog and Agent Guard as the MCP proxy.
See [references/key-rules-and-troubleshooting.md](references/key-rules-and-troubleshooting.md)
for key rules and troubleshooting.

# List MCPs
**Route the request first** — pick which subsection to run BEFORE touching any
file or shell:
| User said… | Run |
| --- | --- |
| "available", "what can I install", "what's in the catalog", "list MCPs", "allowed to install", "approved" without other context | **Available to install** — go straight to `--list-available`; do NOT inspect local files / IDE allowlists first. Do NOT ask whether to check the catalog. |
| "installed", "configured", "connected", "running", "what MCPs do I have" | **Currently installed** |
| ambiguous / both | run **both** in order: Currently installed first, then Available to install, as separate tables |
When Step 0 was exit 0: NEVER invent MCP integrations from outside the catalog.
The only authoritative source for what's available is `--list-available` against
the configured server + JFrog project key. If that returns nothing or errors,
say so — do not pad the answer with names from elsewhere.
## Currently installed
The authoritative, harness-agnostic source of installed MCPs is the config
files themselves — read those first; live connection status is an optional
add-on where the agent provides it.
1. Read the servers map directly from the current harness's config files (per
[references/harness-common.md](references/harness-common.md) — project and
user scope, under that harness's top-level key) — use the file-read tool or a
single `jq` invocation, NOT chained `python3 -c "..."` pipes. For each entry
whose `command` is `npx` and whose `args` include `@jfrog/agent-guard`, show:
display name (the entry key; but where the harness uses a slug key — e.g.
Codex — use the package from `mcp=` instead, per that harness's List
installed), package (`mcp=` in `_JF_ARGS`), server ID (value after
`--server`), scope (project / user).
**Also show each entry that carries a `url` and no `command`** — this skill
writes that shape too (a remote MCP Gateway entry), so a filter on
`@jfrog/agent-guard` alone hides installs it made. Display name and package
are both the entry key (the raw `spec.packageName`), server ID `—`, scope as
above. Such an entry carries no marker of who wrote it, so list it without
asserting whether this skill did. **When its `url` contains `/mcp-gateway/`
(a remote MCP Gateway entry), show that complete `url`, from `http` to the
end — in a table too, never shortened with `...`** — e.g.
`https://acme.jfrog.io/mcp-gateway/mcp/proj/com.supabase%2Fmcp`, not
`.../mcp-gateway/...`.
2. **If the harness exposes an MCP status command or view** (the harness-config
"List installed" column — e.g. Claude Code's `claude mcp list`, Cursor/VS
Code's MCP UI), use it to add live connection status per server. If none
exists, skip this — the config read above is still complete.
3. If a configured entry does not appear in the harness's live list, it is either
pending approval (see [Install → Step 4a](#step-4a-enable-and-verify-the-entry-mandatory))
or filtered by a harness policy (e.g. Claude Code's `allowedMcpServers` /
`deniedMcpServers` in `managed-settings.json`).
## Available to install
If Step 0 was exit 2 (or unknown treated as exit 2), ignore this subsection.
Continue serving the user without Agent Guard. Currently installed still proceeds.
1. Determine **server** and **JFrog project key** per the Pre-flight rules.
`--list-available` does NOT require any existing MCP entry or pre-installed
Agent Guard — `npx --yes --registry "<REGISTRY_URL>" @jfrog/agent-guard`
fetches it on demand, so this works on a fresh machine too.
2. Run this ONCE — do not emit literal `[ ]` brackets. Append `--server
"<SERVER_ID>"` per the Step 1 rule (omit only on the URL+token env path —
`JFROG_URL`+`JFROG_ACCESS_TOKEN`, or legacy `JF_URL`+`JF_ACCESS_TOKEN`):
```
npx --yes \
--registry "<REGISTRY_URL>" \
@jfrog/agent-guard \
--list-available \
--project "<JFROG_PROJECT_KEY>" \
--server "<SERVER_ID>"
```
On non-zero exit, classify per
[key-rules](references/key-rules-and-troubleshooting.md#classify-npx-jfrogagent-guard-failures).
Do not fall back to the usual MCP install routes that skip the approved catalog
and Agent Guard as the MCP proxy.
Exit 0 with only a TSV header (or `--format json` stdout `null`) is an empty
catalog — say so; do not invent names.
Output is a compact TSV — a header line, then one server per line:
`name<TAB>type<TAB>version<TAB>description`. Present the rows directly as a
numbered table — do NOT re-run, redirect, or parse with `python3`/`jq`. `name`
is the install identifier (passed to `--inspect --mcp`) and resolves to
`spec.packageName` (for remote MCPs the two are typically identical, e.g.
`com.supabase/mcp`).
3. **Mark rows already installed rather than dropping them.** For local MCPs the
catalog `name` and the installed `spec.packageName` can differ, so mark a row
`(installed)` if EITHER matches the JSON key of ANY entry in the servers map
OR its `mcp=` value — still show it so the user can reinstall/update. Match
against the whole map, not only the Agent Guard rows: a remote entry carries
no `mcp=`, and its key is the package.

# Remove an MCP
Removal edits local config only and never calls the catalog, so it proceeds on
ANY Step 0 exit code.
An MCP entry that runs `@jfrog/agent-guard`, or one that carries a `url` and no
`command`, must always be removed with these instructions, to make sure the
local config is cleaned up and the OAuth cache is cleared.
1. **Locate the entry across both scopes first.** Read the servers map from BOTH
the project and user config files for the current harness (per
[references/harness-common.md](references/harness-common.md), under that
harness's top-level key), and list every exact match by name with its scope.
Then:
- Exactly one match → delete that entry.
- Present in both scopes (duplicate) → tell the user it exists in both and
ask whether to remove both or just one before editing either file.
- No match → say so; do not edit anything.
Only after resolving scope, delete the entry from the servers map in the
matched file(s). **If the harness file has a "Remove cleanup" section** (e.g.
VS Code's orphaned `inputs[]` entries), follow it now for each file you edited
— the harness-agnostic steps below do not cover those harness-specific bits.
2. **OAuth cache — only after every matching entry is gone.** The
`~/.jfrog/jfrogmcp.conf.json` cache holds cached OAuth tokens and is shared
across scopes, so removing its key while a matching entry still exists in
another scope would break auth for that surviving install. **This file
contains secrets — never print, echo, or surface its contents when reading or
editing it; operate on it by key only.** So:
- If no entry matched in step 1, skip this step entirely.
- If the deleted entry carried a `url` and no `command`, skip this step:
that shape caches no token, so a key of that name is a different
install's.
- If a matching entry remains in the other scope (user kept only one of a
duplicate), leave the cache key in place.
- Only when all matching project and user entries have been deleted (or the
user explicitly asks to clear cached credentials), read
`~/.jfrog/jfrogmcp.conf.json` and delete, from the `servers` object, the key
equal to this MCP's `spec.packageName` (the same identifier used as the JSON
key of the config entry you removed above). If that exact key is absent, do
nothing — do NOT guess or delete a similarly-named key. Then write the file
back. Reading the KEY NAMES under `servers` to locate the match is allowed;
what is forbidden is printing, echoing, quoting, or summarizing any VALUE in
the file, or surfacing the surrounding entries — read the minimum needed to
locate the key and remove it. If the file is absent, skip silently.
3. **Mandatory:** tell the user the exact restart action from the harness's
**Restart** column (per [references/harness-common.md](references/harness-common.md))
— not just "restart the agent" — so the removed entry stops loading.
