# 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.):

```json
{
  "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:

```json
{
    "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"
    }
}
```
