Rescale MCP Server

A Model Context Protocol (MCP) server that provides access to Rescale's Platform API through Claude Desktop and other MCP clients.

Installation & Usage

Prerequisites

• Python 3.11+: Install from python.org or brew install python@3.11
• Git: Usually pre-installed on macOS/Linux, or install from git-scm.com
• pip: Comes with Python installation

Quick Installation

brew install python@3.11
python3 -m venv venv
source venv/bin/activate
python3 --version # make sure its 3.11+

pip install git+https://github.com/rescale-labs/rescale-mcp-server.git

Claude Desktop Setup

1. Get your API token from: https://platform.rescale.com/user/settings/
2. Find your command path by running: which rescale-mcp-server (after activating your environment)
3. Add to Claude Desktop config: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "rescale": {
      "command": "REPLACE_WITH_YOUR_PATH_FROM_STEP_2",
      "args": [
        "--token", "REPLACE_WITH_YOUR_API_TOKEN",
        "--base-url", "https://platform.rescale.com/api/v3"
      ]
    }
  }
}

3. Restart Claude Desktop
4. You'll see Rescale API tools available in Claude!

Getting Started

Once installed, you can start using Rescale directly in Claude Desktop:

1. Open Claude Desktop - The Rescale tools will be automatically available
2. Try basic commands - Ask Claude: "List my Rescale jobs" or "Show available hardware types"
3. Create and submit jobs - Ask Claude: "Create a new compute job using OpenFOAM"

Available Features:

• Job Management: Create, submit, monitor, and control compute jobs and workstations
• File Operations: Upload, download, and manage files and job results
• Resource Discovery: Browse available hardware, software.
• Detailed Documentation: For a complete list of available tools and their usage, see the

🎉 That's it! You can now use Rescale directly in Claude Desktop. The examples below are optional for advanced users.

Advanced Usage Examples (Optional)

The examples below are for developers who want to integrate the Rescale MCP server programmatically into their own applications. Most users can skip this section.

The examples/ directory contains sample integration code showing how to use the Rescale MCP server programmatically:

HTTP Client Example

# Start the MCP server in HTTP mode (in one terminal)
python -m src.rescale_api_mcp_server.cli --token YOUR_TOKEN --transport http --port 8000

# Run the HTTP client example (in another terminal)
cd examples/http
python simple_http_client.py

The HTTP client uses the FastMCP library for clean, high-level integration with MCP servers.

STDIO Client Example

# Run the STDIO client (no separate server needed)
cd examples/stdio
python simple_stdio_client.py

The STDIO client demonstrates direct MCP protocol communication via subprocess, showing lower-level integration.

Both examples will list your Rescale jobs and display detailed job information. Make sure you have:

• Your Rescale API token set in the environment variable RESCALE_API_TOKEN
• Or modify the examples to include your token directly

For Developers

Development Setup

# Clone repository
git clone https://github.com/rescale-labs/rescale-mcp-server.git
cd rescale-mcp

# Create virtual environment and install dependencies
uv venv
source .venv/bin/activate  # On macOS/Linux
uv sync

# Test to verify
python tests/quick_test.py

Manual Server Testing

# Run server directly
python src/rescale_api_mcp_server/server.py --token YOUR_TOKEN --base-url https://platform.rescale.com/api/v3

# HTTP mode for web testing
python src/rescale_api_mcp_server/server.py --token YOUR_TOKEN --base-url https://platform.rescale.com/api/v3 --transport http --port 8000

Running Tests

# Run only unit tests (no API calls required)
python -m pytest tests/unit/ -v

# Run only integration tests (requires API token)
RESCALE_API_TOKEN="your_token_here" python -m pytest tests/integration/ -v

# Run specific test files
python -m pytest tests/unit/test_tool_filters.py -v
python -m pytest tests/integration/test_job_tools.py -v -s

# Run with custom base URL (optional)
RESCALE_API_TOKEN="your_token_here" RESCALE_BASE_URL="https://custom.rescale.com/api/v3" python -m pytest tests/integration/ -v

Test Requirements:

• Unit Tests: No special requirements - test individual components in isolation
• Integration Tests: Require RESCALE_API_TOKEN environment variable for real API calls
• Optional: Set RESCALE_BASE_URL to test against different Rescale environments (defaults to https://platform.rescale.com/api/v3)

Requirements: Python 3.11+, uv package manager, valid Rescale API token
