UTCP BridgeBLOCK
All-in-one MCP server that can connect your AI agents to any native endpoint, powered by UTCP
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
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"
}
}Claude Code (CLI)
For Claude Code (the CLI / IDE extension), register the bridge as a user-scoped MCP server:
claude mcp add-json --scope user utcp '{"type":"stdio","command":"npx","args":["@utcp/mcp-bridge"],"env":{"UTCP_CONFIG_FILE":"/absolute/path/to/.utcp_config.json"}}'Then restart Claude
