UTCP-MCP Bridge

The last MCP server you'll ever need.

A universal, all-in-one MCP server that brings the full power of the Universal Tool Calling Protocol (UTCP) to the MCP ecosystem.

🚀 Quick Start

Add this configuration to your MCP client (Claude Desktop, etc.):

{ "mcpServers": { "utcp": { "command": "npx", "args": ["@utcp/mcp-bridge"], "env": { "UTCP_CONFIG_FILE": "/path/to/your/.utcp_config.json" } } } }

That's it! No installation required. The bridge will automatically:

  • Download and run the latest version via npx

  • Load your UTCP configuration from the specified path

  • Register all your UTCP manuals as MCP tools

  • Provide a unified interface to manage your tool ecosystem

🔧 Configuration

Create a .utcp_config.json file to configure your tools and services:

{ "load_variables_from": [ { "variable_loader_type": "dotenv", "env_file_path": ".env" } ], "manual_call_templates": [ { "name": "openlibrary", "call_template_type": "http", "http_method": "GET", "url": "https://openlibrary.org/static/openapi.json", "content_type": "application/json" } ], "post_processing": [ { "tool_post_processor_type": "filter_dict", "only_include_keys": ["name", "description"], "only_include_tools": ["openlibrary.*"] } ], "tool_repository": { "tool_repository_type": "in_memory" }, "tool_search_strategy": { "tool_search_strategy_type": "tag_and_description_word_match" } }

🛠️ Available MCP Tools

The bridge exposes these MCP tools for managing your UTCP ecosystem:

  • register_manual - Register new UTCP manuals/APIs

  • deregister_manual - Remove registered manuals

  • call_tool - Execute any registered UTCP tool

  • search_tools - Find tools by description

  • list_tools - List all registered tool names

  • get_required_keys_for_tool - Get required environment variables

📁 What is UTCP?

The Universal Tool Calling Protocol (UTCP) allows you to:

  • Connect to any API via HTTP, OpenAPI specs, or custom formats

  • Use command-line tools with automatic argument parsing

  • Process text and files with built-in utilities

With this MCP bridge, all your UTCP tools become available in Claude Desktop and other MCP clients.
