15 tools listed at last check
  • 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/deprecated flags, name-collision count, and a fact-based health verdict (healthy | issues | unknown).
  • 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), disambiguate (when unsure), known_brand (we recognize a strong product but it has no official MCP — e.g. CodeRabbit), research (watchlist
  • 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>=1000), remote-capable count, github-linked count, and captured_at. No invented metrics.
  • 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 discovery times. Optional limit 1–50 (default 20).
  • census_coverage Public transparency report (same payload as GET /v1/coverage). Unmetered. Live D1 census/identity/remote/protocol/adoption/pipeline counts plus method notes — never invents completeness percentages or a brand_audit punch list.
  • 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, verified_change, security. Requires x-api-key. Prefer webhook_url (https) so your agent can receive POST callbacks; email optional. Returns a wat
  • 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 limits. This is a first gate, not a security audit. refresh=if_stale requires x-api-key.
  • 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 wallet.
  • 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 stamp_json. Cost matches preflight. Never connect without a stamp. PASS is not a malware scan or permission review.
  • 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 or tail. Never invents lookalikes. Cost 1.
  • 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 entry without guessing (url → remote_url, npx → npm package, uvx → PyPI package) and returns one PASS / REVIEW / BLOCK / UNKNOWN verdict per
  • 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_change, security, endpoint_moved, registry_status, spec_era_change. Cursor-paginated: pass next_cursor back as since. Filter by events, ser
