Overview

What is Universal Tool Calling Protocol (utcp Client)?

Universal Tool Calling Protocol (utcp Client) is an MCP server that acts as a bridge between the Universal Tool Calling Protocol (UTCP) ecosystem and any MCP client. It exposes all tools registered via UTCP as MCP-compatible tools and provides a direct UTCP client interface for registering, deregistering, searching, and calling tools. It is designed for developers who need a single integration point to manage and extend their tool ecosystem.

How to use Universal Tool Calling Protocol (utcp Client)?

Install the server using Docker (docker-compose up --build), a bash script (./run.sh), or a PowerShell script (./run.ps1). Alternatively, for a standalone UTCP client, download simple-utcp-client-mcp.py and configure your MCP client with the uv command and script path. The server exposes HTTP endpoints on ports 8776 (UTCP Client MCP), 8777 (UTCP Proxy MCP), and 8778 (web UI). Connect your MCP client by adding entries for utcp-client-mcp-local and/or utcp-proxy-mcp-local with the appropriate URLs.

FAQ from Universal Tool Calling Protocol (utcp Client)

What is the difference between the UTCP client and UTCP proxy modes?

The UTCP client mode lets you register, deregister, search, and call UTCP providers directly. The UTCP proxy mode exposes all tools already registered via UTCP as MCP tools without needing direct management.

What are the runtime dependencies?

Python 3, uv (package manager), and Docker (optional). The server automatically installs Python packages: utcp, fastmcp, fastapi, and python-dotenv.

Where does the server store provider and tool definitions?

Provider and tool definitions are loaded from the data/ directory (e.g., data/providers.json). You can also specify a providers_file_path in .utcp_config.json.

What transport does the server use?

The server communicates via HTTP on ports 8776 (UTCP client MCP), 8777 (UTCP proxy MCP), and 8778 (web UI). No authentication or TLS is mentioned in the README.

What are the known limitations?

The README does not document any specific limitations. The web UI is described as having more features "coming soon."
