Opik MCP Server

The official Model Context Protocol (MCP) server for Opik, the open-source LLM observability and evaluation platform, built by Comet. Plug your AI host (Claude Code, Cursor, VS Code Copilot, MCP Inspector) directly into your Opik workspace: read traces, log scores, save prompt versions, and ask Ollie, Opik's in-product AI assistant, investigative questions, all from the chat.

People connecting DevOps & monitoring tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Opik MCP Server

before you install - you'll need

Set OPIK_API_KEY, OPIK_MCP_ANALYTICS_SOURCE before connecting. OPIK_WORKSPACE, COMET_URL_OVERRIDE are optional or environment-specific per the README.

Claude Code

claude mcp add comet-ml-opik-mcp -- npx -y opik-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "comet-ml-opik-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "opik-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
