_ is it live, free and safe measured by this hub
Is Tollbooth OAuth2 Collector live?
Yes — it answered the hub's last check (checked 5h ago). It answered 100% of checks over the last 30 days.
Is Tollbooth OAuth2 Collector free to use?
Yes — the hub reached it with no key and no payment.
What tools does Tollbooth OAuth2 Collector have?
4 tools: store_code, retrieve_code, collector_status, service_status.
Is Tollbooth OAuth2 Collector 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.

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.

  • collector_status reads open 5h ago

    Health check — shows the number of pending authorization codes and TTL.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • service_status reads open 5h ago

    Report the running build so a redeploy can be verified. Free. Delegates to the SDK's canonical ``build_service_status`` — the single source of the service_status payload shape — so this collector reports the same envelope as every other DPYC service. The load-bearing field is ``build_info.fastmcp_cloud_git_commit_sha``: the commit Horizon actually deployed. The post-merge deploy-verify probe reads it to confirm the live service redeployed the merged sha; with no ``service_status`` tool to probe, that sha reads as ``<none>`` and an otherwise-healthy deploy is flagged as "did not land". The vault/courier/operator fields are ``False``/empty by construction — this is an unauthenticated community utility with no operator runtime.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • store_code changes data unknown never probed

    Store a sealed OAuth2 authorization code. Called by the serverless callback function after the browser redirect. The ``state`` carries BOTH the patron npub (the lookup/retrieve key) and the operator npub (the PUBLIC key the code is sealed to) — see the SDK's ``pack_oauth_state``. The code is sealed with NIP-44 to the operator so only that operator's nsec can open it; the Neon row is keyed by the patron npub, so retrieval (``retrieve_code(state=patron_npub)``) is unchanged.

    mcp-tool

    {
  "type": "object",
  "required": [
    "code",
    "state"
  ],
  "properties": {
    "code": {
      "type": "string",
      "description": "The authorization code from the OAuth provider."
    },
    "state": {
      "type": "string",
      "description": "The packed state (``patron_npub.operator_npub``)."
    }
  },
  "additionalProperties": false
}
    arguments 18 lines
  • retrieve_code changes data unknown never probed

    Retrieve a stored authorization code (one-time read, auto-deleted). Called by the originating MCP server to pick up the code after the user has authorized in the browser. Returns the encrypted code which the caller decrypts using the same state token.

    mcp-tool

    {
  "type": "object",
  "required": [
    "state"
  ],
  "properties": {
    "state": {
      "type": "string",
      "description": "The state token (patron npub) used during authorization."
    }
  },
  "additionalProperties": false
}

_ try it 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 02c643a9bdda1c74.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/02c643a9bdda1c74/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 know
card completeness
80%

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.
