Configure Cedar policy enforcement and Ed25519 signed receipts for Claude Code tool calls. Use when setting up projects that need cryptographic audit trails, policy-gated tool execution, or compliance-ready evidence of agent actions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. - **Ed25519 receipts** record the name of each tool that ran, signed with your key. - **Offline verification** via `npx @veritasacta/verify`. No server, no account, no trust in the operator. ## Problem AI agents make decisions that affect money, safety, and rights. The Claude Code session log records what happened, but the log is: - Mutable — anyone with access can edit it - Unsigned — there is no way to prove integrity - Operator-bound — verification requires trusting whoever holds the log For compliance contexts (finance, healthcare, regulated research), this is not …

How to install
mdr add wshobson/agents/protect-mcp-setup@sha256:c1aad7bc2145d5deThe line at the top of this page pins the label git:20261105.9ecda7f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
