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 Medical Terminologies server.
Medical Terminologies tools are categorised as Read (24), Execute (3). Each category has a recommended default policy.
Open source. One binary. Zero dependencies.
