Use Intercept, the open-source MCP proxy. Write YAML rules for each tool — rate limits, argument validation, or deny rules — then run Intercept in front of the Memento server.
Memento tools are categorised as Read (9), Write (5), Destructive (3). Each category has a recommended default policy.
Deterministic policy on every MCP tool call. Per-identity grants. Full audit log.
