_ is it live, free and safe measured by this hub
Is signal-lab-catalog live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is signal-lab-catalog free to use?
Yes — the hub reached it with no key and no payment.
What tools does signal-lab-catalog have?
7 tools: export_catalog, search_catalog, get_entry, compare_entries, catalog_info, list_filters, get_source_urls.
Is signal-lab-catalog 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.

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.

  • catalog_info open 1h ago

    Return the catalog's notice, schemaVersion, generated time, entry count and the download URLs of the full catalog as JSON and CSV.

  • list_filters open 1h ago

    List the values the catalog uses for type, badge, auth, category, license, task, verified and lastVerified, with how many entries have each. Call this first to pick exact filter values.

  • get_source_urls open 1h ago

    Return where each entry's data comes from: the provider's site, docs and evidence pages, the license or terms URL with the license note, and the lastVerified date, plus the Signal Lab page. Pass up to 25 slugs, or the same filters as search_catalog (all entries if none). A URL the catalog does not record is left out.

  • export_catalog unknown never probed

    Export the Signal Lab catalog as JSON or CSV: every entry, or only those matching the same filters as search_catalog (no result cap). Optional fields picks columns by catalog field name. CSV has a header row, joins lists with "; " and repeats the catalog notice in the last column. Also returns the static download URLs.

  • search_catalog unknown never probed

    Find free and free-to-start financial data sources, tools and models in the Signal Lab catalog by text and by filters (category, type, access badge, sign-up needed, license, task, verified, verified_since; see list_filters for the values). Returns up to 25 summary rows in name order, each with lastVerified and sitePageUrl. Use get_entry for every field of one entry, export_catalog for the whole list, get_source_urls for provider and terms links.

_ 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 d528e400835f7ec8.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/d528e400835f7ec8/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/d528e400835f7ec8/badge.svg)](https://brick.blue/agent/d528e400835f7ec8?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.
