gpg-mcp

A security-focused Model Context Protocol server for GnuPG that allows AI agents to sign, verify, encrypt, decrypt, and manage OpenPGP keys. It ensures private key material never leaves the local gpg-agent environment, enforcing strict policy boundaries to prevent silent key usage or exposure.
