A Model Context Protocol (MCP) server implementation for SwanLab, combining SwanLab-OpenAPI & FastMCP.

✨ Features

Core Features

• Workspace Queries - List accessible workspaces and enumerate workspace projects
• Project Queries - List projects and inspect a specific project with run summaries
• Run Queries - Inspect runs with normalized fields (id, state, profile, user)
• Metric Queries - Fetch metric tables with consistent columns, rows, and total
• API Integration - Provide read-only access through SwanLab OpenAPI (swanlab.Api)

Tech Stack

• Language: Python 3.12+
• Core Framework: FastMCP (v2.14.4+)
• API Client: SwanLab SDK
• Config Management: Pydantic Settings

🚀 Quick Start

❗️Configuration

Add the following configuration to your relative mcp config list

{
  "mcpServers": 
    ...
    {
    "swanlab-mcp": {
      "command": "uvx",
      "args": ["--from", "swanlab-mcp", "swanlab_mcp", "--transport", "stdio"],
      "env": {
        "SWANLAB_API_KEY": "your_api_key_here"
      }
    }
  }
}

For Claude Code Users, you can config like this:

claude mcp add --env SWANLAB_API_KEY=<your_api_key> -- swanlab_mcp uvx --from swanlab-mcp swanlab_mcp --transport stdio

Prerequisites

• Python >= 3.12
• SwanLab API Key (get it from SwanLab)

Installation

# Using uv (recommended)
uv sync

# Or using pip
pip install -e .

Configuration

Environment Variables

Create a .env file and configure your API key:

cp .env.template .env

Edit the .env file:

SWANLAB_API_KEY=your_api_key_here

Running

# Using stdio transport (default)
python -m swanlab_mcp

# Or using CLI
python -m swanlab_mcp --transport stdio

# Check version
python -m swanlab_mcp --version

Usage

After configuration, restart Claude Desktop to interact with SwanLab via the MCP protocol.
