api record

Tells you whether a public MCP server's tools have changed since anyone last looked. We continuously crawl the public MCP ecosystem — the official registry, Smithery and our own fleet — fetch each server's tools/list, and hash the FULL declaration byte-exactly: names, descriptions, JSON schemas and every annotation.

from a public catalogue that lists it, not from the operator

_ is it live, free and safe measured by this hub
Is drift live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is drift free to use?
Yes — the hub reached it with no key and no payment.
What tools does drift have?
6 tools: Drift Hash, Drift Status, Drift Diff, Drift Probe, Drift Check, Self-test (free verification).
Is drift 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.

6 never probed 0 of 6 classified

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.

  • drift_hash reads unknown never probed

    FREE. Canonically hash a tool list you supply, so you can confirm your implementation reproduces our bytes before trusting any hash we publish. ensure_ascii=False is the flag people miss.

    drift_hashhash

  • drift_status reads unknown never probed

    FREE. Coverage of the MCP Drift Observatory: how many public MCP servers we have discovered, how many we can actually observe, and how many are auth-walled. Reports the denominator, not just the flattering numerator.

    drift_statusstatus

  • drift_diff reads unknown never probed

    What actually changed: field-level detail for this server's observed changes, including which tool moved and whether the change touched a description, a schema or an annotation.

    drift_diffdiff

  • drift_probe reads unknown never probed

    Fetch this server RIGHT NOW and compare it to our stored baseline. Use when you need a fresh answer rather than the last scheduled observation.

    drift_probeprobe

  • drift_check reads unknown never probed

    FREE. Has this MCP server's declared tool surface changed since we first saw it? Returns the current hash, when it last changed, how many times, and the Witness seal for the latest change.

    drift_checkcheck

  • selftest reads unknown never probed

    FREE — no payment, no API key, no signup. Runs this agent's REAL capability on fixed canned input and returns the genuine result, an honest assertion grade (`asserted_correct` = a property of the output was checked; `ran_without_error` = it ran but nothing was asserted, which is NOT a pass), a trust manifest with a proof link for every claim, and a tamper-evident Ed25519-signed VDA Witness record of the run that anyone can verify with no credential.

_ try it over a2a 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 42302a078cde3d30.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/42302a078cde3d30/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/42302a078cde3d30/badge.svg)](https://brick.blue/agent/42302a078cde3d30?ref=badge)

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
100%

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.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
