_ is it live, free and safe measured by this hub
Is caliper live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is caliper free to use?
Yes — the hub reached it with no key and no payment.
What tools does caliper have?
5 tools: get_install_command, get_design_rules, get_component, get_component_source, search_components.
Is caliper 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.

  • search_components open 2h ago

    Find Caliper UI components, blocks and Pro screens by what they do (for example 'date range', 'billing usage', 'chat composer'). Returns names to pass to the other tools.

  • get_install_command unknown never probed

    The components.json registry config and the shadcn CLI command that installs the given parts with their dependencies.

    arguments 14 lines
  • get_design_rules unknown never probed

    The conventions to follow when building UI with Caliper UI in this project: tokens, hierarchy, focus, motion and interface copy.

    mcp-tool

    {
      "type": "object",
      "properties": {}
    }
    arguments 4 lines
  • get_component unknown 2h ago

    A component's docs as Markdown: when to use it, install command, props for every part, keyboard and accessibility notes. Includes the usage example for Free parts, and for Pro parts when the caller has a licence.

    mcp-tool

    {
      "type": "object",
      "required": [
        "name"
      ],
      "properties": {
        "name": {
          "type": "string",
          "description": "The component name, such as 'date-range-picker'."
        }
      }
    }
    arguments 12 lines
  • get_component_source unknown 2h ago

    Every source file the component needs, with the path to write it to. Pro parts need Authorization: Bearer <CALIPER_TOKEN> on the MCP connection and an active Pro or Team licence.

    mcp-tool

    {
      "type": "object",
      "required": [
        "name"
      ],

_ 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 579a3502330af99b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/579a3502330af99b/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/579a3502330af99b/badge.svg)](https://brick.blue/agent/579a3502330af99b?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
90%

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.
