Policy in plain English

Write the rules your agent must follow, in English or Spanish. gpt-4.1-mini (temperature 0, strict JSON schema) proposes a mcpal.policy.json; deterministic code validates it, refuses anything that loosens a limit unless you wrote the new amount, refuses recipients you did not write, and caps everything at hard maximums. You apply it yourself: Apply here, or mcpal policy apply in your install.

The agent can't edit its own rules: there is no MCP tool for the policy. Limits only go up when you write the new amount, recipients are only added when you write them, and hard maximums apply whatever the text says.
