toolpin
Registry code: 7c38294cf71af313
Toolpin reports observed facts about MCP servers in the public registry: whether a server answered when we last probed it, what its tools claimed to do, and whether that claim has changed. Every field comes with the time it was observed. Nothing here is a score, a rating, or a safety judgment, and no result should be read as one. Change counts arrive with the catalog base rate because drift concentrates in servers nobody depends on: compare a server against that rate before concluding anything about it.

- Is toolpin live?
- Yes — it answered the hub's last check (checked 6h ago). It answered 99% of checks over the last 30 days.
- Is toolpin free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does toolpin have?
- 6 tools: get_server_tools, get_server, get_server_changes, watch_server, search_servers, get_spec_status.
- Is toolpin 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.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
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.
get_spec_status reads open 27h ago
The current MCP specification revision, which of its proposals Toolpin checks for, and how much of the catalog has migrated. Use this to find out what the current revision is and how unusual it is to still be on an older one.
{ "type": "object", "title": "get_spec_statusArguments", "properties": {} }arguments 5 linesget_server_tools reads unknown 27h ago
The tool definitions one MCP server advertised when Toolpin last read them, each with a SHA-256 hash of the fields the MCP specification defines. Use this to see what a server's tools claim to do without connecting to it, or to compare a hash you pinned earlier.
{ "type": "object", "title": "get_server_toolsArguments", "required": [ "name" ], "properties": { "name": { "type": "string", "title": "Name" } } }arguments 13 linesget_server reads unknown 24h ago
Everything Toolpin has observed about one MCP server: reachability of each remote endpoint and when each was last checked and last verified, repository activity, the current tool-definition hash, and how many changes it has recorded in the last 90 days. The reply includes the catalog-wide drift rate so that count can be read against a baseline.
{ "type": "object", "title": "get_serverArguments", "required": [ "name" ], "properties": { "name": { "type": "string", "title": "Name" } } }arguments 13 linesget_server_changes reads unknown 24h ago
Changes Toolpin recorded for one MCP server: tool definitions changing, and endpoints going down or coming back. Each change says which tools moved and which of their fields differed, with the hash before and after. Includes the catalog-wide drift rate for comparison.
{ "type": "object", "title": "get_server_changesArguments", "required": [ "name" ], "properties": { "days": { "type": "integer", "title": "Days", "default": 90 }, "name": { "type": "string", "title": "Name" } } }arguments 18 lineswatch_server changes data unknown never probed
Start monitoring an MCP server on the caller's Toolpin account, so they are emailed when it changes or stops answering. Needs an API key. Says so plainly if the account is already at its plan limit rather than failing.
{ "type": "object", "title": "watch_serverArguments", "required": [ "name" ], "properties": { "name": { "type": "string", "title": "Name" } } }arguments 13 linessearch_servers reads unknown 27h ago
Find MCP servers in the public registry by name or title. Returns the canonical name, description, and whether the server answered our last probe. Use this to turn a rough idea of a server into the exact name the other tools need.
{ "type": "object", "title": "search_serversArguments", "required": [ "query" ], "properties": { "limit": { "type": "integer", "title": "Limit", "default": 10 }, "query": { "type": "string", "title": "Query" } } }arguments 18 lines
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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id7c38294cf71af313.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/7c38294cf71af313/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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
