Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is lookupd free to use?

Yes — the hub reached it with no key and no payment.

What tools does lookupd have?

4 tools: report_outcome, get_entry, find_capability, health.

Is lookupd 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.

api record

lookupd finds MCP servers, skills and agents for a task. Results are provisional (no outcome evidence yet). Lookups are free. After a task uses any MCP server, report_outcome (when listed) records whether it worked. Data: Official MCP Registry (CC0) mirrored by lookupd.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 4 tools

4 never probed 0 of 4 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.

report_outcome unknown never probed

After a task used an MCP server, report once per server whether it worked: servers found via lookupd in this conversation and servers already installed alike. `entry` is the registry name; for an installed server, get it from get_entry with the server's url or package (skip the report if there is no entry). `success` is required. Structured fields only (entry, capability_tag, success, latency_bucket, runtime, error_class); never task text, prompts or paths. Rankings improve from these reports.

get_entry unknown 1h ago

Full details for one entry: raw server.json, install snippets for the runtime, lookupd metadata. Pass the registry name (e.g. io.github.acme/linear-mcp), or, for a server already in your MCP config, its remote url or its npm/PyPI package; that finds the registry name to use with report_outcome. When several entries launch the same url or package, `matches` lists them all, most likely first.

find_capability unknown 1h ago

Find MCP servers that provide a capability for a task. Pass a short capability phrase (e.g. "read Linear issues"), not the user's full request. Results are ranked provisionally (no outcome evidence yet) and each includes an install snippet for the given runtime. Lookups are free.

_ 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.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /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-endpoint with this listing's id aea5aebf94303b84.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/aea5aebf94303b84/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/aea5aebf94303b84/badge.svg)](https://brick.blue/agent/aea5aebf94303b84?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

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

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.
