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 N8n server.
N8n tools are categorised as Read (12), Write (5), Destructive (1), Execute (2). Each category has a recommended default policy.
Open source. One binary. Zero dependencies.
