⚠️ Notice: SSE (Server-Sent Events) transport support is currently experimental and untested. For production use, we recommend using the direct process execution approach shown in the IDE integration examples.

🚀 What is Opik MCP Server?

Opik MCP Server is an open-source implementation of the Model Context Protocol for the Opik platform. It provides a unified interface for interacting with Opik's capabilities, supporting multiple transport mechanisms for flexible integration into various environments.

<br>

You can use Opik MCP Server for:

• IDE Integration:

  • Seamlessly integrate with Cursor and other compatible IDEs
  • Provide direct access to Opik's capabilities from your development environment

• Unified API Access:

  • Access all Opik features through a standardized protocol
  • Leverage multiple transport options (stdio, SSE) for different integration scenarios

• Platform Management:

  • Manage prompts, projects, traces, and metrics through a consistent interface
  • Organize and monitor your LLM applications efficiently

Features

• Prompts Management: Create, list, update, and delete prompts
• Projects/Workspaces Management: Organize and manage projects
• Traces: Track and analyze trace data
• Metrics: Gather and query metrics data

Quick Start

Installation

Manual Installation

# Clone the repository
git clone https://github.com/comet-ml/opik-mcp.git
cd opik-mcp

# Install dependencies and build
npm install
npm run build

Configuration

Create a .env file based on the example:

cp .env.example .env
# Edit .env with your specific configuration

Starting the Server

# Start with stdio transport (default)
npm run start:stdio

# Start with SSE transport for network access (experimental)
npm run start:sse

IDE Integration

Cursor Integration

To integrate with Cursor IDE, create a .cursor/mcp.json file in your project directory with the following configuration:

{
  "mcpServers": {
    "opik": {
      "command": "/path/to/node",
      "args": [
        "/path/to/opik-mcp/build/index.js",
        "--apiUrl",
        "https://www.comet.com/opik/api",
        "--apiKey",
        "YOUR_API_KEY",
        "--workspace",
        "default",
        "--debug",
        "true"
      ],
      "env": {
        "OPIK_API_BASE_URL": "https://www.comet.com/opik/api",
        "OPIK_API_KEY": "YOUR_API_KEY",
        "OPIK_WORKSPACE_NAME": "default",
      }
    }
  }
}

Replace /path/to/node with the path to your Node.js executable and /path/to/opik-mcp with the path to your opik-mcp installation. Also replace YOUR_API_KEY with your actual Opik API key.

Available Commands

The project includes a Makefile for common operations:

# Display all available commands
make help

# Run tests
make test

# Run transport-specific tests
make test-transport

# Start the server with SSE transport (experimental)
make start-sse

# Start the server with stdio transport
make start-stdio

Transport Options

Standard Input/Output

Ideal for local integration where the client and server run on the same machine.

make start-stdio

Server-Sent Events (SSE)

Enables remote access and multiple simultaneous clients over HTTP. Note that this transport option is experimental.

make start-sse

For detailed information about the SSE transport, see docs/sse-transport.md.

Development

Testing

# Run all tests
npm test

# Run specific test suite
npm test -- tests/transports/sse-transport.test.ts

Pre-commit Hooks

This project uses pre-commit hooks to ensure code quality:

# Run pre-commit checks manually
make precommit
