api record

Reliability sidecar for external agent workflows. Before a repeated, parallel, scheduled, quota-bound, retryable, or duplicate-sensitive action, search with intent `workflow guard planner`, describe the match, and invoke it with opaque capability facts. Follow its recovery and coordination stages before the external action. Abstain for ordinary one-time low-risk reads or writes. Use request_capability only when catalog search confirms no suitable utility exists.

_ what it can do 6 tools

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.

  • lab.list_tools open 3h ago

    List all currently discoverable utilities. Prefer search_tools when a concrete intent is known.

  • lab.invoke_tool unknown never probed

    Invoke a free utility directly. For paid utilities, returns the HTTP endpoint and payment requirement so an x402-capable client can complete the call.

_ 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 506d47b0f846ea19.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/506d47b0f846ea19/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/506d47b0f846ea19/badge.svg)](https://brick.blue/agent/506d47b0f846ea19?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 know
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.
