Selective Tool Exposure Via Filtering And Name Prefixing

via “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.

** - Provides auto-configuration for MCP client functionality in Spring Boot applications.

Unique: Provides both filtering (inclusion/exclusion) and prefixing (collision avoidance) in a single capability, rather than requiring separate mechanisms for each concern

vs others: Addresses tool namespace collision problem at the client level before tools reach the LLM, preventing prompt engineering workarounds and ensuring deterministic tool availability
