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 Twilio server.
Twilio tools are categorised as Read (21), Write (9), Execute (2), Financial (4). Each category has a recommended default policy.
Open source. One binary. Zero dependencies.
