Agent Custody MCP Server

Proof of what your AI agents did. Every tool call an agent makes through the gateway becomes a signed record of who authorized it, what the agent saw, what it did, and what depended on it, checkable by anyone with the public keys. What each check proves, and against whom, is a table, not a slogan. It runs locally over stdio via the published package.

People who work with audit, cedar and provenance and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
