Evaluate the currently loaded JamJet policy against a candidate MCP tool name. Returns the matched rule, the decision (allow / block / require_approval / audit), and the matched glob pattern. Use this to dry-run a tool call before issuing it, or to explain why a previous call was blocked. Read-only and side-effect free — does not write to the audit log.

List every rule in the currently loaded JamJet policy, in declaration order. Each entry includes the rule index, action (allow / block / require_approval / audit), and the glob pattern it matches. Use this to inspect the active policy without reading the YAML file directly, or to verify a rollout placed rules in the expected order. Read-only.

Report the path to the policy file currently loaded by this server, plus the number of rules it contains and the policy schema version. Use this once at session start to confirm the server has the expected policy attached. Read-only.
