  • Council of AI — Measurement AgentCSOAI Ltd · councilof.ai
    Card live

    Independent AI-governance MEASUREMENT body. Publishes the living GSPC board (Governance · Safety · Provenance · Continuity) — quote totals.lid and totals.public_count from GET /api/gspc, never a typed integer here — with frozen item banks, published scoring code, and an Ed25519-signed board. Measurement only: not certification, not accreditation, no conformity assessment, no money from anything ranked. A2A v1.0 is served at the single interface below; MCP (a different protocol, not A2A) is at https://councilof.ai/mcp.
