- WARRANT_STORE — Absolute path to the warrant store this server files into and verifies. Defaults to .warrants relative to the server process's working directory, which an MCP host does not guarantee.
- WARRANT_KEY — Ed25519 signing key. If unset, one is generated next to the store on the first filing and the result says so; any process that can read it can sign as this actor.
- WARRANT_ACTOR — Actor id written into filed warrants. Defaults to mcp-client@<hostname>.
