Speckle MCP Server

A Model Context Protocol (MCP) server for interacting with Speckle, the collaborative data hub that connects with your AEC tools.

Overview

This MCP server acts as a bridge between Speckle's API and client applications and exposes a set of tools that allow users to:

• List and search Speckle projects
• Retrieve detailed project information
• Access model versions within projects
• Retrieve and query objects and their properties from specific versions

Installation

Prerequisites

• Python 3.13 or higher
• Speckle account with a personal access token
• uv for dependency management and virtual environments

Setup

1. Clone this repository:

   git clone https://github.com/bimgeek/speckle-mcp.git
   cd speckle-mcp

2. Ensure you have Python 3.13 installed:

   python --version  # Should show Python 3.13.x

3. Install dependencies using uv:

   uv pip install -r requirements.txt

Configuration

Environment Variables

The server requires the following environment variables:

• SPECKLE_TOKEN: Your Speckle personal access token (required)
• SPECKLE_SERVER: The Speckle server URL (defaults to https://app.speckle.systems)

MCP Configuration

To use this server with Claude, you need to update your MCP configuration file. The configuration file is typically located at:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add or update the "speckle" entry in the mcpServers section:

{
  "mcpServers": {
    "speckle": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/speckle-mcp",
        "run",
        "speckle_server.py"
      ],
      "env": {
        "SPECKLE_TOKEN": "YOUR_SPECKLE_API_TOKEN_HERE",
        "SPECKLE_SERVER": "https://app.speckle.systems"
      }
    }
  }
}

Replace /path/to/speckle-mcp with the actual path to the directory containing the speckle_mcp package.
