InfiniteMCP

A meta-MCP server that gives Claude access to the entire ecosystem of MCP servers through semantic search and dynamic tool discovery.

What is InfiniteMCP?

InfiniteMCP is a an MCP server that acts as a universal gateway to thousands of other MCP servers. Instead of manually configuring each MCP server you want to use, InfiniteMCP lets Claude discover, understand, and use any MCP server on demand through natural language queries.

Think of it as an "MCP server of MCP servers" - a single connection that unlocks the entire MCP ecosystem.

How It Works

Claude asks: "Search for MCP servers that can crawl websites"
    ↓
InfiniteMCP searches 1000+ indexed MCP servers
    ↓
Returns: [firecrawl-mcp, web-scraper-mcp, playwright-mcp, ...]
    ↓
Claude: "Use firecrawl to get content from example.com"
    ↓
InfiniteMCP dynamically loads firecrawl-mcp and executes the request
    ↓
Returns the crawled content to Claude

The Three Core Functions

InfiniteMCP exposes three powerful tools to Claude:

  1. search_mcp - Semantic search across all known MCP servers

    Input: "web search"
    Output: [brave-search-mcp, tavily-mcp, serper-mcp, ...]
    
  2. get_functions - Discover what an MCP server can do

    Input: mcp_id (e.g., "brave-search-mcp")
    Output: [brave_web_search, brave_local_search, ...]
    
  3. run_function - Execute a function from any MCP server

    Input: mcp_id, function_name, arguments, credentials
    Output: Function result
    

Features

  • 🔍 Semantic Search - Find MCP servers using natural language, powered by state-of-the-art embedding models
  • 🚀 Dynamic Loading - MCP servers are loaded on-demand, no pre-configuration needed
  • 🔐 Smart Credential Management - Securely handles API keys and credentials, with user prompts for missing values
  • 🧩 Tool Discovery - Automatically discovers all available functions from any MCP server
  • 📚 Comprehensive Index - Pre-indexed with 1000+ MCP servers from the ecosystem
  • Efficient - Caches connections and metadata for fast repeated access

Installation

Prerequisites

  • Python 3.11+
  • CUDA-capable GPU (recommended for embedding search)
  • Node.js 18+ (for running discovered MCP servers)

Setup

Local install will try a cuda and fallback to cpu

# Clone the repository
git clone https://github.com/yourusername/infinitemcp.git
cd infinitemcp

# Install dependencies
pip install -r requirements.txt

# Build the MCP server index (one-time setup)
./extracto

Usage

With Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "infinitemcp": {
      "command": "python",
      "args": ["-m", "infinitemcp"],
      "env": {
        "INFINITEMCP_DB": "/path/to/infinitemcp/db"
      }
    }
  }
}

Example Interactions

Discovering servers:

You: "I need to search the web for information about MCP servers"
Claude: [uses search_mcp("web search")]
Claude: "I found several options. Brave Search looks good. Let me use that..."

Using a server:

Claude: [uses get_functions("brave-search-mcp")]
Claude: [uses run_function with brave_web_search]
Claude: "Here's what I found..."

Handling credentials:

Claude: [attempts run_function("github-mcp", ...)]
InfiniteMCP: "Missing required credential: GITHUB_TOKEN"
Claude: "I need your GitHub token to access that API..."
You: "Here it is: ghp_..."
Claude: [retries with credentials]
