⚠️ 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.


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

1# Clone the repository
2git clone https://github.com/comet-ml/opik-mcp.git
3cd opik-mcp
4
5# Install dependencies and build
6npm install
7npm run build

Configuration

Create a .env file based on the example:

1cp .env.example .env
2# Edit .env with your specific configuration

Starting the Server

1# Start with stdio transport (default)
2npm run start:stdio
3
4# Start with SSE transport for network access (experimental)
5npm 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:

1{
2  "mcpServers": {
3    "opik": {
4      "command": "/path/to/node",
5      "args": [
6        "/path/to/opik-mcp/build/index.js",
7        "--apiUrl",
8        "https://www.comet.com/opik/api",
9        "--apiKey",
10        "YOUR_API_KEY",
11        "--workspace",
12        "default",
13        "--debug",
14        "true"
15      ],
16      "env": {
17        "OPIK_API_BASE_URL": "https://www.comet.com/opik/api",
18        "OPIK_API_KEY": "YOUR_API_KEY",
19        "OPIK_WORKSPACE_NAME": "default",
20      }
21    }
22  }
23}

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:

1# Display all available commands
2make help
3
4# Run tests
5make test
6
7# Run transport-specific tests
8make test-transport
9
10# Start the server with SSE transport (experimental)
11make start-sse
12
13# Start the server with stdio transport
14make start-stdio

Transport Options

Standard Input/Output

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

1make start-stdio

Server-Sent Events (SSE)

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

1make start-sse

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

Development

Testing

1# Run all tests
2npm test
3
4# Run specific test suite
5npm test -- tests/transports/sse-transport.test.ts
