Turn any Python library into an LLM Tool in seconds.

AllBeAPI is a high-performance bridge that instantly exposes any Python library as a Model Context Protocol (MCP) server. It enables Large Language Models (Claude, ChatGPT, etc.) to execute local Python code, manipulate dataframes, process images, and interact with your system—safely and efficiently.

Built on the latest StreamableHTTP protocol for maximum compatibility with Claude Desktop, LangChain, and Cursor.

Installation

pip install allbeapi

Quick Start

Expose pandas (or any other library) to your LLM with a single command:

# Install, generate, and serve in one go
allbeapi start pandas

The server will start on http://127.0.0.1:8000/mcp.

Client Configuration

To use your new tool with Claude Desktop or other MCP clients, add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "pandas": {
      "command": "uv",
      "args": [
        "run",
        "allbeapi",
        "start",
        "pandas"
      ]
    }
  }
}

Key Features

Zero-Config Generation

Automatically inspects any installed Python package, extracts public APIs, and generates a fully compliant MCP server. No manual schema definition required.

Smart Serialization Engine

LLMs struggle with complex objects. AllBeAPI handles them automatically:

• DataFrames: Converted to markdown or JSON previews.
• Images: Automatically encoded or saved to temp storage.
• Classes: Stateful object management allows you to instantiate classes and call methods on instances.

Local & Secure

Runs entirely on your machine. No data leaves your network. You control the host binding (default 127.0.0.1) and execution environment.

Modern Stack

• Typer: For a robust, ergonomic CLI experience.
• FastAPI / Starlette: High-performance async networking.
• Pydantic: Strict data validation and schema generation.

Advanced Usage

Inspect a Library

Check which functions will be exposed before generating code:

allbeapi inspect numpy

Generate Only

Generate the server code without running it (useful for customization):

allbeapi generate matplotlib --output-dir ./my-server
