Endpoint Filtering And Selective Exposure

Expose your FastAPI endpoints as Model Context Protocol (MCP) tools, with Auth!

Unique: Implements filtering at the schema conversion stage (before MCP tool generation) rather than at runtime, preventing filtered endpoints from ever being exposed as MCP tools. This is more secure than runtime filtering because it eliminates the possibility of filter bypass through protocol manipulation.

vs others: More secure than exposing all endpoints and relying on LLM prompts to avoid dangerous calls, and more flexible than hardcoding endpoint lists because filtering can be based on tags, paths, or custom predicates.

Expose your FastAPI endpoints as Model Context Protocol (MCP) tools, with Auth!

Unique: Provides declarative endpoint filtering at the MCP layer using path patterns and tags, enabling selective tool exposure without modifying the underlying FastAPI application. Filtering is applied during schema conversion, not at runtime.

vs others: Allows selective endpoint exposure without modifying FastAPI code or creating separate application instances, whereas alternatives typically require separate API gateways or endpoint duplication.
