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.

  • list_recent_trades reads open 11h ago

    The most recently disclosed trades — newest first. Accepts the same branch/role/since/until/type filters as search_trades so an agent can scope to a chamber or window in one call.

  • aggregates reads open 11h ago

    Summary stats over the filtered set: totals, branch split, most-active officials, top tickers bought/sold (per individual stock), top sectors bought/sold, potential conflict count, date range. Accepts the same branch/role/since/until/type/ticker filters as search — pass branch=congress + role=Senate + since=YYYY-MM-DD to scope. Use this BEFORE paginating search_trades when you only need ranked counts.

_ 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 7aa05319e2462a4b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/7aa05319e2462a4b/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
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.
