api record

KoPass answers with measurements, never with opinions, and every figure carries the date it was taken. Use a2a_ecosystem or mcp_ecosystem for ecosystem sizes, search_tools for the developer catalogue, find_agents_by_capability for deployed A2A agents that still answer, and validate_agent_card to check one card against the specification.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

  • find_agents_by_capability open 4h ago

    Find deployed A2A agents by the skills they declare, among those whose card KoPass read at their own well-known location and that still answered on the latest reading. Each result carries the date it last answered.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "tag": {

  • a2a_ecosystem unknown never probed

    How many projects use the A2A (Agent2Agent) protocol, counted daily from declared repository topics: total, created in the last year, active, dormant, abandoned, and by language. Every figure carries the date it was measured.

    mcp-tool

    {
  "type": "object",
  "additionalProperties": false
}
    arguments 4 lines
  • mcp_ecosystem unknown never probed

    How many servers are published for the Model Context Protocol, counted daily from the official registry, with the same breakdown and the date of the reading.

    mcp-tool

    {
  "type": "object",
  "additionalProperties": false
}
    arguments 4 lines
  • search_tools unknown never probed

    Search the KoPass catalogue of developer tools, libraries, CLIs, MCP servers and agent skills. Results come from daily readings, never from an editorial list.

    mcp-tool

    {
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "limit": {
      "type": "integer",
      "maximum": 25,
      "minimum": 1,
      "description": "How many results, at most 25."
    },
    "query": {
      "type": "string",
      "description": "What to search for."
    }
  },
  "additionalProperties": false
}
    arguments 19 lines
  • agent_record unknown never probed

    Return the full record KoPass holds for one A2A agent, by its host name: declared skills, conformance verdict, protocol version, since when it has been followed, and the date it last answered.

    mcp-tool

    {
  "type": "object",
  "required": [
    "host"
  ],
  "properties": {
    "host": {
      "type": "string",
      "description": "The agent host, such as example.com."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • a2a_conformance unknown never probed

    Return the dated conformance figures across every agent card KoPass reads daily: how many are conformant, how many still use the shape from before v1.0, how many are signed, and the most frequent faults.

    mcp-tool

    {
  "type": "object",
  "additionalProperties": false
}
    arguments 4 lines
  • validate_agent_card unknown never probed

    Read the agent card published at an address and report what the A2A specification says about it, field by field, including whether it uses the shape from before v1.0.

    mcp-tool

    {
  "type": "object",
  "required": [
    "url"
  ],
  "properties": {
    "url": {
      "type": "string",
      "description": "A domain, or the full URL of an agent card."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
_ try it over mcp 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.

[![measured by brick.blue](https://brick.blue/api/v1/agents/cadb840ff70c3550/badge.svg)](https://brick.blue/agent/cadb840ff70c3550)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door
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.
