概览

What is Tool Gating MCP?

Tool Gating MCP is an intelligent proxy/router for the Model Context Protocol (MCP) that allows clients like Claude Desktop to dynamically discover and use tools from multiple MCP servers through a single connection point. It prevents context bloat by selecting only the most relevant tools for each task.

How to use Tool Gating MCP?

Install Python 3.12+ and uv, clone the repo, create a virtual environment, install dependencies, and run tool-gating-mcp (HTTP API server) or integrate it as a native MCP server using mcp-proxy. Configure Claude Desktop to point to Tool Gating MCP; then use built-in tools like discover_tools, provision_tools, and register_tool.

Key features of Tool Gating MCP

  • Proxy architecture routes calls to multiple backend MCP servers
  • Dynamic tool discovery via semantic search across all servers
  • Smart provisioning loads only relevant tools within token budgets
  • Transparent execution routes tool calls to the correct backend
  • 90%+ reduction in context usage compared to loading all servers
  • Zero configuration – Claude Desktop only needs Tool Gating MCP

Use cases of Tool Gating MCP

  • Reducing context bloat when using many MCP servers (e.g., Exa, Puppeteer, Context7, Desktop Commander)
  • Dynamically adding tools during a conversation without restarting Claude Desktop
  • Improving AI tool selection by presenting only the most relevant tools per query
  • Lowering token costs by minimizing the number of tool definitions sent per request

常见问题

1

What problem does Tool Gating MCP solve?

It solves context bloat caused by loading 100+ tools from multiple MCP servers at startup, and removes the need to restart Claude Desktop to add new servers during a conversation.

2

How does it reduce context usage?

It uses semantic search and token budget enforcement to select and provision only the most relevant tools (typically 2–3) out of a large pool, cutting token consumption by over 90%.

3

What are the prerequisites?

Python 3.12+, the `uv` package manager, and optionally `mcp-proxy` for native MCP integration with Claude Desktop.

4

How does tool discovery work?

Tools are registered with metadata, tags, and token estimates. User queries are embedded using a sentence transformer, and tools are scored by cosine similarity plus tag matches (0.2 boost per matching tag).

5

Can I integrate new MCP servers with Tool Gating MCP?

Yes. You can register tools from external MCP servers via the API endpoints (`/api/tools/register`) or use the AI-assisted server registration endpoint (`/api/mcp/ai/register-server`).
