description	Audit existing ToolHive catalog server entries for drift: whether the pinned image still exists, the upstream repo is still alive and active, and the declared env vars and network-permission profile still match what the server actually needs. Use whenever asked to audit, health-check, sweep, or spot-check catalog entries / server.json files for staleness, broken images, dead repos, abandoned projects, or wrong env-vars/permissions - for the community tier, the official tier, the whole registry, or a named subset. Report-only; it never edits entries. NOT for reviewing a new submission (use mcp-review) or creating one (use add-mcp-server).

Catalog audit

Audit catalog entries that are already in the registry for three kinds of drift:

1. Still valid - the pinned OCI image still resolves; repository.url still loads.
2. Still active - the upstream repo isn't archived/disabled and isn't stale.
3. Still canonically correct - declared env vars and the network-permission profile match what the upstream project actually documents and requires.

This is report-only. Produce findings for a human to triage; never edit a server.json, open a PR, or change permissions. The output is a dated markdown report under audits/.

Checks 1 and 2 are mechanical and run via the bundled script. Check 3 needs judgment over upstream docs and is done by fanning out sub-agents. Grading rules and severity live in references/audit-criteria.md - read it before writing findings.

Step 1 - resolve scope

Infer scope from the request, don't ask for rigid flags. Map intent to a server set:

• "the community servers" / "community tier" -> --tier community
• "official servers" -> --tier official
• "the whole catalog" / "everything" -> --tier all
• "re-check X, Y, Z" / a list of names -> --names X,Y,Z
• a specific registry tree -> --registry toolhive|official|all (default toolhive)

The repo has two server trees: registries/toolhive/servers/ (contribution path, default) and registries/official/servers/ (curated subset). Default to toolhive unless the user clearly means otherwise.

Skills (registries/toolhive/skills/) are out of scope unless explicitly asked. If asked, audit them separately (their packages[] carry registryType: git with a ref/subfolder and registryType: oci images - check the git ref resolves and the repo is active; there are no env vars or network permissions to canonicalize).

State the resolved scope and the entry count back to the user before crawling, so a mistaken scope is caught early.

Step 2 - mechanical checks (script)

Run the bundled deterministic script. It needs gh (authenticated) and docker or skopeo on PATH.

python3 .claude/skills/catalog-audit/scripts/check_entries.py \
  --tier community \
  --out <scratch>/mechanical.json

Use --names a,b,c for a subset, or --paths .../server.json ... for exact files. The script prints a JSON array (also written to --out): per entry it reports imageExists / imageMethod, repoResolves, archived, disabled, lastPushISO, monthsStale / isStale, openIssues, plus dockyard and tier. null on an image/repo field means inconclusive (tooling couldn't run / transient), not a pass.

It also reports officialDrift: for an Official-tier entry, whether its registries/official mirror has drifted from the registries/toolhive source - false (in sync), a list of differing top-level keys (e.g. ["repository"]), or null (no mirror, e.g. Community-tier). A non-empty list is a finding worth reporting and means a fix needs applying to both copies.

Step 3 - deep canonical-correctness checks (sub-agents)

For each in-scope entry, spawn a sub-agent to do check 3. Keep it cheap: these are independent, doc-reading tasks. For a handful of entries, launch Task agents in parallel (batches of ~8). For a large sweep (dozens), prefer the Workflow tool to pipeline the fan-out if the user has opted into it; otherwise batch Task agents.

Give each sub-agent:

• the server.json path and its parsed env vars + permissions block,
• the repository.url (and note if dockyard:true, so it reads the upstream repo, not the dockyard wrapper),
• the relevant criteria from references/audit-criteria.md.

Instruct each agent to read the upstream README and relevant source (via gh api repos/{owner}/{repo}/readme, gh api/get_file_contents for files, search_code for env-var references, or WebFetch), then return structured findings only:

{
  "name": "<server>",
  "envVars": [{"name": "...", "issue": "...", "severity": "...", "evidence": "<url-or-file:line>"}],
  "permissions": [{"issue": "...", "severity": "...", "evidence": "..."}],
  "couldNotVerify": ["..."]
}

Each finding must cite upstream evidence (a URL or file:line). Findings without evidence are not actionable - drop them or mark couldNotVerify.

Step 4 - verify findings before reporting (adversarial)

Single-pass deep checks over-report - this is not optional cleanup, it's a core step. A cheap finder reliably flags plausible-but-wrong issues: a host that a leading-dot allow_host already covers, an "unused" var its own evidence shows is used, an insecure_allow_all that is actually justified, a 401 from a healthy OAuth-gated remote.

For every high/critical finding (and ideally all of them), spawn an independent agent - a stronger model than the finder - to re-check it against upstream, prompted to refute by default: "confirm only if you can re-derive this from upstream; mark refuted if the entry is actually correct; uncertain if you can't tell." Drop refuted findings; keep confirmed ones with the verifier's note. In the first official-tier run this stage refuted ~6 high and ~21 medium false positives that had survived the finder.

When fixes are later applied, re-verify each one against upstream while editing (grep the actual var name / host) - a cheap third check that catches the cases a verifier still misses (e.g. a contested host the second pass got wrong).

Step 5 - merge and write the report

Merge mechanical results (step 2) with deep findings (step 3) into severity-ranked findings using the scale in the criteria file. Write to audits/<scope>-<YYYY-MM-DD>.md (create audits/ if absent; get the date with date +%F). Use this structure:

# Catalog audit - <scope> - <date>

Scope: <description> (<N> entries). Methods: docker/skopeo image probe, gh repo API,
sub-agent upstream-doc review. Report only - no entries were modified.

## Summary
| entry | image | repo | active | env issues | perm issues | worst |
|-------|-------|------|--------|-----------|-------------|-------|
...

## Critical
...
## High
...
## Medium
...
## Low
...

## Could not verify
<entries/fields where a check was inconclusive>

## Clean
<entries with no findings>

Each finding lists the entry, category, detail, evidence (URL/command), and a suggested action for the human (since this is report-only). Lead with the worst.

Step 6 - hand off

Show the user the summary table and the top findings inline. Do not commit the report or edit any entry unless the user explicitly asks. If they want fixes, that's a separate pass (and mcp-review / add-mcp-server cover the editing rules). When fixing an Official-tier entry, remember it has a mirror copy (see Notes) that must be updated too.

Notes

• Inconclusive is not clean. Surface null image/repo results and unreachable upstream docs as "could not verify," never as passing.
• Check wildcard coverage before flagging a missing host. allow_host is Squid-style: a leading-dot entry (.example.com) already matches every subdomain. List the actual allow_host and confirm the needed host isn't already covered before reporting it missing. (Both the finder and a verifier missed this on aws-documentation in the first run.)
• A remote endpoint returning 401/403 is alive, not a finding - it's auth/OAuth-gated. Only DNS failure, connection refused, 404, 5xx, or TLS errors mean it may be down.
• Official-tier entries are mirrored in registries/official/servers/ (a copy, not a symlink). Flag when an entry's registries/official copy has drifted from its registries/toolhive source - that drift is itself a finding. And any fix to an Official-tier entry must be applied to both copies (CI reconciles only the auto-populated metadata / tool_definitions, not the hand-edited fields).
• Be fair on staleness. A small, finished server can be quiet for good reasons; weigh monthsStale against the server's scope before flagging.
• Be fair on insecure_allow_all. Servers that reach arbitrary user-supplied hosts (fetch, scrapers, browsers, db/cluster/registry clients) may legitimately need it; flag it only where a concrete scoped host list is feasible, and propose that list.
