api record

Usage Lab meters usage for usage-based billing. Typical flow: list_meters (or create_meter once), then record_usage_events with a stable idempotency_key per event (reuse the same key on retries: it returns duplicate and counts once), then get_meter_rollups for monthly per-customer totals. Account tools need the user's own Usage Lab API key sent as 'Authorization: Bearer <key>' on this MCP connection (free key at https://usage-lab.pages.dev/signup/). get_docs needs no key.

_ is it live, free and safe measured by this hub
Is usage-lab live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is usage-lab free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does usage-lab have?
6 tools: get_meter_rollups, create_meter, list_meters, get_account, get_docs, record_usage_events.
Is usage-lab 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.

  • get_meter_rollups auth-required 1h ago

    Monthly totals per customer for one meter, recomputed from raw events (GET /api/v1/meters/{meter}/rollups). Returns total_quantity and per-subscription quantity and event_count. Needs your API key.

    arguments 21 lines
  • create_meter auth-required never probed

    Create a meter once (POST /api/v1/meters). aggregation: sum (add up value, e.g. tokens), count (number of events, e.g. tool calls) or unique_count (distinct unique_value, e.g. active users). Re-creating an existing key returns meter_exists (harmless). Free plan: 3 meters. Needs your API key.

    }
    arguments 30 lines
  • list_meters auth-required 1h ago

    List the meters on your Usage Lab account (key, name, aggregation sum | count | unique_count). Needs your API key (Authorization: Bearer).

    mcp-tool

    {
      "type": "object",
      "properties": {}
    }
    arguments 4 lines
  • get_account auth-required 1h ago

    Your account: plan, event and meter limits, event_count and first_event_at (GET /api/v1/account). Needs your API key.

    {
      "type": "object",
      "properties": {}
    }
    arguments 4 lines
  • get_docs auth-required never probed

    Quickstart for the Usage Lab metering API and this MCP server: how to get a free API key, connect, create a meter, record idempotent usage events and read rollups. No API key needed.

      "type": "object",

  • record_usage_events auth-required never probed

    Record 1-100 usage events in one all-or-nothing batch (POST /api/v1/usage). Every event MUST carry its own idempotency_key; retrying with the same keys is safe (results say created / duplicate / conflict). Needs your API key.

_ 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 c205afb054ef8772.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c205afb054ef8772/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.
