The publisher's own command. Not a PlugMCP endpoint.

Credentials from the publisher
- DATABASE_URL — Postgres connection string the agent's queries run against. Give it a least-privilege role: Midplane constrains what SQL is allowed, it does not widen or narrow what the role itself can reach.
- MIDPLANE_POLICY_FILE — Path to a policy YAML granting per-table read/read_write access, tenant scoping, and column masking. Omit for the safe default: reads allowed, writes and DDL denied. Generate one with `npx midplane init`.
- DB_PATH — Where the local SQLite audit log is written. Defaults to ~/.midplane/audit.db; read it back with `midplane audit denies`.
- MIDPLANE_TELEMETRY — Set to 0 to disable anonymous usage telemetry (DO_NOT_TRACK=1 also works). Never includes SQL, table or column names, or identifiers.
