What is the Agent MCP Server?

Fail-closed quality gate and hash-chained receipt ledger for AI agent workflows.

What it actually does

Agents that grade their own homework ship low-quality output. agent-gate turns that discipline into tools an agent must actually pass: a fail-closed checklist and an append-only, hash-chained receipts ledger. It is Fleet Mode, an agent-orchestration doctrine, made into a runnable tool. Receipts over hype, enforced by the data structures.

  • Fail-closed. — A check counts as satisfied only if it is explicitly true. Missing proof is not proof. (Mirrors a promotion gate, not an informal check.)
  • Tamper-evident receipts. — Every decision is recorded as (decision, metric, value, verdict) linked into a sha256 chain. Edit or delete any past receipt and verify_chain() returns false. The honest log is enforced by the structure, not by good intentions
  • Human-gated by default. — "Any irreversible/outward act got human approval" is a required check. Agents draft, humans approve
