MCP Category Routing

Example Use Cases

• 1

  Expose different subsets of tools and resources based on URL path categories.

• 2

  That require efficient filtering of MCP primitives per HTTP session without per-message overhead.

• 3

  Organize and manage multiple categories of tools within a single MCP server.

Description

This library integrates with the Model Context Protocol (MCP) SDK for .NET to filter MCP primitives per HTTP session based on route parameters, enabling different categories of tools to be exposed on different URL paths from a single MCP server. It performs filtering at session connection time to avoid per-message overhead, supports multiple categories per tool, and configurable behavior for uncategorized primitives. This allows developers to organize and expose tools, prompts, and resources efficiently by category in their MCP servers.
