# protect-mcp — Policy Enforcement + Signed Receipts
Cryptographic governance for every Claude Code tool call. Each invocation is
evaluated against a Cedar policy and produces an Ed25519-signed receipt that
anyone can verify offline.
## Overview
Claude Code runs powerful tools: `Bash`, `Edit`, `Write`, `WebFetch`. By default
there is no audit trail, no policy enforcement, and no way to prove what was
decided after the fact. `protect-mcp` closes all three gaps:
- **Cedar policies** (AWS's open authorization engine) evaluate every tool call
before execution. Cedar deny is authoritative.
