census_audit_config

Resolves every entry without guessing (url → remote_url, npx → npm package, uvx → PyPI package) and returns one PASS / REVIEW / BLOCK / UNKNOWN verdict per entry under a built-in policy, plus CENSUS-AUDIT/1 text, valid_until_epoch and exit_code (1 on any BLOCK). UNKNOWN is never upgraded to PASS. Cost 1 credit per config per UTC day; keyless callers get one config of ≤25 entries per IP per day. Not a malware scan; PASS is not a sandbox. Strip env/headers before sending.

Cursor-paginated: pass next_cursor back as since. Filter by events, server_names or namespace_domain. Only real transitions, never 'still fine'. Unmetered in v1; poll hourly. Not a malware scan.

Live D1 census/identity/remote/protocol/adoption/pipeline counts plus method notes — never invents completeness percentages or a brand_audit punch list.
census_credits

Returns stars, last-push recency, gone/archived/deprecated flags, name-collision count, and a fact-based health verdict (healthy | issues | unknown).

This is a first gate, not a security audit. refresh=if_stale requires x-api-key.

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/confirmed_absent). Prefer official_match=true rows. Never invent servers.

Cost matches preflight. Never connect without a stamp. PASS is not a malware scan or permission review.

Returns total servers, healthy/issues counts, popular (gh_stars>=1000), remote-capable count, github-linked count, and captured_at. No invented metrics.

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 watch id + HMAC secret (X-Census-Signature: sha256=…). Free tier: 5 watches; pro: 50.
