Plugin System

Extend servers with plugins, adapters, and context extensions

FrontMCP’s plugin system lets you add cross-cutting capabilities — caching, logging, context extensions, and more — without modifying your tools or resources. Plugins use the @Plugin decorator and DynamicPlugin base class to hook into the request lifecycle.

Capability	Example
Register tools, resources, prompts	Dynamically add capabilities at startup
Add providers	Inject services into the DI container
Extend context	Add this.remember, this.cache to tool contexts
Hook into flows	Intercept request lifecycle stages
