name: Perfect Corp — A2A Agent Card
description: 'An A2A Agent Card served by Perfect Corp from its own documentation host. It describes the YouCam API documentation agent and, notably, carries an MCP extension rather than an A2A skill set: its `capabilities.extensions[0]` points at https://docs.perfectcorp.com/mcp, the documentation MCP server, which was independently confirmed to answer `tools/list` with six documentation tools.'

  path: /.well-known/agent-card.json
  canonical: true
  host: docs.perfectcorp.com
agent:
  name: YouCam API Documentation | Perfect Corp.
  url: https://docs.perfectcorp.com/a2a
  documentationUrl: https://docs.perfectcorp.com/
  version: 0.0.1
  protocolVersion: 0.3.0
  preferredTransport: HTTP+JSON
grade_basis: 'Graded against A2A 1.0.0. Hard checks all pass — `capabilities` is an object, `protocolVersion` is present (0.3.0), and `skills` is an array. The optional fields that usually decide near-conformant are all present too: preferredTransport, defaultInputModes and defaultOutputModes.'
deviations:
- field: skills
  observed: '[]'
  impact: The array is present and therefore conformant, but it is EMPTY, so the card advertises no callable skill. An A2A client reading this card learns the agent exists and where its documentation and MCP endpoint are, and nothing it can invoke over A2A.
- field: protocolVersion
  observed: 0.3.0
  impact: Declares the 0.3.x protocol line rather than 1.0.0. Not a conformance failure — the card is served at the canonical 0.3+ path — but it dates the implementation.
- field: capabilities.extensions[0]
  observed: https://modelcontextprotocol.io -> params.url https://docs.perfectcorp.com/mcp
  impact: The real capability behind this card is MCP, not A2A. The card functions as a pointer to the documentation MCP server; the three PRODUCT MCP servers on mcp-api-01.makeupar.com are not referenced from it.
