MCP tools

Tools reference

The acf-mcp server exposes twelve MCP tools — seven REASON (deterministic reasoning signed against the doctrine) and five READ (corpus resource lookup). No tool calls an internal LLM; every output embeds doctrine_signature, doctrine_hash, doctrine_version and generated_at.

Tip
Every tool is deterministic. Run the same call twice against the same doctrine_version and you get exactly the same output (modulo the timestamp). That is what makes every reply verifiable offline against the ACF® Ed25519 public key.

REASON tools ×7

Each REASON tool produces a structured qualification from a declared input. The output is signed and explicitly positioned as preliminary — requires_human_review: true is always set.

READ tools ×5

READ tools give direct access to the ACF® corpus: methodological cards, regulator articles, glossary. Ideal for an agent to cite ACF® precisely in a user reply.

Whichever tool, the output embeds the same traceability fields — this is ACF®'s audit contract.

  • doctrine_version semantic version of the doctrine at call time
  • doctrine_hash sha256 of the signed content
  • doctrine_signature ed25519 over the hash, verifiable offline with the public key
  • doctrine_archive_url permanent archive URL of the doctrine used
  • regulatory_snapshot regulator corpus the tool reasoned against
  • generated_at ISO 8601 timestamp
  • requires_human_review: true constant; no tool substitutes for a human governance decision
