VERAX

stdio

The body an agent asks before it acts: decide, approve, and keep a signed record on your machine.

Getting Started

npx @getmcp/cli add io.github.verax-ai/verax

Requires Node.js 18+. Community-contributed server. Review source before installing.

Required Environment Variables

VERAX_ISSUER
Issuer the agent's token must carry. The body refuses to start without one; `verax doctor` names what is missing.
VERAX_JWKS_URL
Where the body fetches the keys that verify that token.
VERAX_AUDIENCE
Audience the token must name, so a token minted for something else is refused.
VERAX_STATE_DIR
Directory the ledger, keys and approvals live in. It stays on this machine.
VERAX_POLICY_FILE
Policy the gate applies. @verax-ai/proxy ships policy/default.json, which denies what it does not name.
