Agent Middleware Spec

I built this repo so anyone can check an Agent Middleware receipt on their own machine. You need no account, no network call and no trust in me.

It holds five things:

• spec/ has the permit, receipt and key set formats (v0.1) plus shared test vectors.
• verifier/ runs every test vector against the Python reference verifier.
• sdk/python/ is the offline receipt verifier and the b2a-verify-receipt CLI.
• sdk/typescript/ is a second, independent verifier built on Node's own Ed25519.
• mcp-server/ is an MCP server over stdin and stdout. It calls that TypeScript verifier. The tools are verify_receipt and inspect_receipt.

Quick start

pip install -e "./sdk/python[verify]"
python verifier/check_vectors.py
(cd sdk/typescript && npm test)

Usage examples live in examples/.
