Overview
MagicTunnel sits between MCP clients and a collection of tools. Instead of requiring users to know each tool’s name and parameter schema, it accepts a natural-language request, selects a suitable tool, maps the request to its parameters, and runs it.
It is aimed at people building or managing MCP tool collections, especially when a large catalog is difficult for users to navigate. The project also provides a dashboard and protocol gateway features for managing tools and connecting to network MCP services.
Key Features
- Exposes smart tool discovery as a natural-language interface for selecting and calling tools.
- Supports rule-based or LLM-based tool selection in its configuration.
- Provides a web dashboard for tool management, monitoring, logs, configuration, and MCP testing.
- Includes a supervisor for process management, health monitoring, and automatic restarts.
- Translates between HTTP, SSE, and WebSocket protocols for network MCP services.
- Supports YAML-defined tools and generators for OpenAPI, gRPC, and GraphQL sources.
Use Cases
- MCP administrators can offer one entry point when users struggle to find the right tool in a large catalog.
- Developers can expose existing API operations as MCP tools using the included API generators.
- Teams can manage and monitor tools, configuration, and service logs through the web dashboard.
- Integrators can connect network MCP services that use different supported transport protocols.
Getting Started
Clone the repository, then follow the README’s setup guide for the desired configuration. For semantic discovery with local embeddings, the README describes building with semantic-search support and using Ollama; a standalone MCP server mode is also available.
Alternatives
- mcp-gateway: mcp-gateway consolidates MCP servers and REST APIs behind one endpoint, while MagicTunnel focuses on discovering and invoking tools through a smart tool.
- MCPHub: MCPHub emphasizes centralized server management and routing strategies, while MagicTunnel pairs tool discovery and invocation with a supervisor and capability-generation tools.

Considerations
- Semantic discovery has additional setup: the documented local embedding path requires Ollama and an embedding model. The README also describes rule-based selection as an option.
- The project has multiple build and run modes, including a standalone server and a supervisor with a dashboard, so choose the setup that matches your needs.
- The supplied repository details do not specify a license, and no topics are listed.
