UTCP-MCP Bridge MCP Server

All-in-one MCP server that can connect your AI agents to any native endpoint, powered by UTCP

Installation

Add the following to your MCP client configuration file.

Configuration

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

You are about to run a universal MCP server that brings UTCP tools into your MCP client ecosystem, enabling centralized management and seamless tool orchestration without extra setup.

How to use

To use this MCP server with your MCP client, add a stdio-based MCP connection that runs via npx and points to the UTCP bridge package. You only need to configure the bridge once in your MCP client, and it will automatically load your UTCP configuration and expose all UTCP tools through the MCP interface.

How to install

Prerequisites: make sure you have Node.js and npm or npx installed on the machine where you run your MCP client.

1) Ensure you have a path for your UTCP configuration file, for example /path/to/your/.utcp_config.json.

2) In your MCP client configuration, add the UTCP bridge as a new MCP server entry using the following settings.

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

Additional configuration and notes

Create a .utcp_config.json file to configure your UTCP tools and services. You can define how variables are loaded, which tools are exposed, and how you want results to be processed. The bridge will load your UTCP configuration from the path you specify and register all UTCP manuals as MCP tools.

Example configuration elements you can include in .utcp_config.json are variable loaders, manual call templates, post-processing rules, and tool repositories. You can also define a search strategy and keep tools isolated per project.

Security and management notes

Environment isolation is supported, so each project can provide its own UTCP config. Be mindful of which UTCP manuals you register and expose through MCP to avoid leaking sensitive information.

Tool and endpoint overview
