Integra Agent Guard

The buyer/developer side of Legal Context Protocol commerce. Two packages, Apache-2.0, free forever — no account, no key, no token, nothing to sign up for.

Package

What it is

@integraledger/agent-guard

Verify before sign, as a type and as a runtime guarantee. A paying agent fetches the terms the seller advertised, recomputes the fingerprint, and halts before any signing key is invoked if they disagree.

@integraledger/lcp-mcp-server

Read-only Model Context Protocol server exposing LCP tools to an AI agent — verify before pay, compute an atrHash, extract and place references across ten commerce protocols.

npm install @integraledger/agent-guard
npm install @integraledger/lcp-mcp-server

Both work against any seller — the checks run over what a seller publicly advertises, so they are useful whether or not that seller has ever heard of Integra. Nothing here calls home: no telemetry, no callback, no network request other than fetching the terms the seller pointed you at.

The standard

The Legal Context Protocol is co-stewarded by Integra Ledger and AAA-ICDR. These packages implement its buyer side over the public @integraledger/lcp-* protocol packages. The seller-side application they interoperate with is separately licensed and is not part of this repository.
