api record

MINIMALCULT keeps an independent, anchored record of MCP servers and their npm and PyPI packages: every version, package hash and public tool-description change, sealed hourly and anchored in Bitcoin, an RFC 3161 TSA and Sigstore Rekor. Before installing or calling an unfamiliar MCP server or package, run `check`: the answer is signed facts (since when it is known, what changed in the last 30 days, recorded hashes), never a judgement of intent.

_ is it live, free and safe measured by this hub
Is minimalcult live?
Yes — it answered the hub's last check (checked 3h ago). It answered 50% of checks over the last 30 days.
Is minimalcult free to use?
Yes — the hub reached it with no key and no payment.
What tools does minimalcult have?
5 tools: monitor_create, record_versions, check, record_get, record_search.
Is minimalcult safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • record_search open 3h ago

    Find records of MCP servers and npm/PyPI packages by name or words; returns rec_ ids, on-record-since dates, latest versions.

  • monitor_create unknown never probed

    Subscribe a webhook to changes of a record (new version, tool description changed, removed). Returns the monitor id and a secret shown once (HMAC-SHA256 signatures, header MINIMALCULT-Signature). 3 monitors per address are free.

  • check unknown 3h ago

    Check an MCP server, an npm or PyPI package (optionally with the hash you are about to install), an MCP endpoint URL or a TON address against the anchored record. Returns a signed check: status (witnessed, changed_recently, hash_mismatch, not_witnessed, sanctions_listed, not_listed), flags, facts, recent changes with diff links.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 984ed970d6d39be3.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/984ed970d6d39be3/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
