The card was fetched anonymously from the canonical /.well-known/agent-card.json path and saved verbatim. No other AAIF host serves a card: aaif.io, goose-docs.ai, agents.md, a2a-protocol.org, agentgateway.dev and registry.modelcontextprotocol.io all 404 on both the canonical and the legacy /.well-known/agent.json path. card: agentic-ai-foundation-agent-card.json discovery: path: /.well-known/agent-card.json canonical: true host: modelcontextprotocol.io x-evidence: fetched: '2026-08-30' url: https://modelcontextprotocol.io/.well-known/agent-card.json http_status: 200 content_type: application/json grade: conformant grade_basis: >- Graded against A2A 1.0.0.

The actual callable agent surface on this host is the MCP endpoint at https://modelcontextprotocol.io/mcp, which the card does not name. notes: - >- The skills the card points at are real, fetchable Agent Skill documents (HTTP 200, text/markdown); both are saved verbatim in skills/ and indexed in skills/_index.yml. maintainers: - FN: Kin Lane email: info@apievangelist.com
