## Security scan

- **Status:** clean
- **Scanned:** 2026-09-12T11:15:48.340Z

- **CVEs:** no coverage — this entry has no package coordinates to query OSV against, so "no known CVEs" is NOT asserted for it.

## Tools

15 declared. Observed from a live `tools/list` probe.
- `census_lookup` — Get the live health verdict for one MCP server by its exact registry name (e.g. 'io.github.owner/name'). Returns stars, last-push recency, gone/archived/depreca
- `census_search` — Search MCP servers by keyword or partial name (e.g. 'github', 'postgres'). Returns ranked matches with health/trust. Also returns: resolved_query (auto typo fix
- `census_stats` — Ecosystem headline numbers from the live census (same payload as GET /v1/stats). Unmetered. Returns total servers, healthy/issues counts, popular (gh_stars>=100
- `census_recent` — Newest MCP servers by real first_seen_at (same payload as GET /v1/recent). Unmetered. Only rows with a known first-seen date — never invents or guesses discover
- `census_coverage` — Public transparency report (same payload as GET /v1/coverage). Unmetered. Live D1 census/identity/remote/protocol/adoption/pipeline counts plus method notes — n
- `census_watch_subscribe` — Subscribe this agent (or a human email) to alerts for ONE specific MCP server. Fires only on real observed changes: remote_down, remote_up, health_change, verif
- `census_watch_list` — List active per-server watches for this API key. Requires x-api-key.
- `census_watch_unsubscribe` — Deactivate a watch by id. Requires x-api-key that owns the watch.
- `census_preflight` — Evaluate one exact MCP server under a documented built-in install policy. Returns PASS, REVIEW, or BLOCK with evidence reasons, freshness, digests, and explicit
- `census_policy_list` — List the exact immutable Preflight v1 built-in policy objects, canonical ruleset, and policy digests. Unmetered.
- `census_credits` — Show remaining Census credits for this API key (wallet after the UTC-month grant). Unmetered. Without a key, returns anonymous unique-per-day remaining — not a 
- `census_stamp` — Census stamp for one exact MCP server under a built-in policy. Same input as census_preflight. Returns the preflight body plus compact CENSUS-STAMP/1 text and s
- `census_lookalikes` — Contested identity for one exact server_name: official_for, name_collision_count, and up to 10 other census server_name values sharing the same namespace brand 
- `census_audit_config` — Audit a whole MCP client config in one call (.mcp.json, claude_desktop_config.json, .cursor/mcp.json, .vscode/mcp.json, Codex config.toml text). Resolves every 
- `census_changes` — The Census change feed (CENSUS-CHANGES/1): observed transitions across every server — server_new, remote_down, remote_up, tools_changed, health_change, verified

## Install

**Verdict: review** — Installable, but 2 things to check first: No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
**Cautions** (coverage gaps and advisories — never blocking)
- No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"census\": {\n      \"type\": \"http\",\n      \"url\": \"https://api.mcpcensus.com/mcp\"\n    }\n  }\n}"
```

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on someone else's infrastructure; read-only tool surface.
- Floor 9, ceiling 27 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
