Argus MCP includes a composable plugin framework that intercepts MCP requests at well-defined hook points. Plugins run inside the middleware chain and process every request in priority order.
The plugin system ships with eight built-in plugins for common tasks like secrets detection, rate limiting, and response caching. You can also write your own plugins or integrate with external policy engines.
