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 Ast server.
Ast tools are categorised as Read (11), Write (1), Execute (1). Each category has a recommended default policy.
Open source. One binary. Zero dependencies.
