_ is it live, free and safe measured by this hub
Is limpide-tools live?
Yes — it answered the hub's last check (checked 58m ago). It answered 100% of checks over the last 30 days.
Is limpide-tools free to use?
Yes — the hub reached it with no key and no payment.
What tools does limpide-tools have?
1 tool: generate_exercises.
Is limpide-tools 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.

  • generate_exercises open 58m ago

    Verified maths exercises for tutors, human or AI: product equations (équations produit) of degree 2 and 3, first year of maturité, in French (Swiss course conventions) or English. Each exercise is built from its solutions, so its answer key is always right. Each one sets a named trap, the error it tests (hidden common factor, difference of squares, sum of squares, x as a common factor, grouping, perfect square). Returns the statement for the student and, for the tutor only, the solution set, explained steps with the trap step and its note, and figureUrl: the graph of the function, whose zeros are the solutions. Never show the solution to the student. Give a seed to get the same exercise again; its id names it. Give a date (YYYY-MM-DD) instead for the exercise of that day, the same for every reader: today's date gives the exercise of the day. Deterministic: use this instead of writing exercises and answer keys yourself.

_ 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 c3ea7e498babec45.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c3ea7e498babec45/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
50%

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.
