Verdict

Pick Opik MCP if you prefer its approach (drive your opik llm-observability workspace from your ai host — read traces, log scores, save prompts, ask ollie).

Pick Elasticsearch MCP Server if you prefer the more popular, battle-tested option, and you want a verified, documented setup.

Add Opik MCP

Install / run

uvx opik-mcp

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "opik-mcp": {
      "command": "uvx",
      "args": [
        "opik-mcp"
      ],
      "env": {
        "OPIK_API_KEY": "<your-key>",
        "OPIK_WORKSPACE": "<your-workspace>"
      }
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.

Add Elasticsearch MCP Server

Install / run

docker run -i --rm -e ES_URL -e ES_API_KEY docker.elastic.co/mcp/elasticsearch stdio

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "elasticsearch-mcp-server": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "ES_URL",
        "-e",
        "ES_API_KEY",
        "docker.elastic.co/mcp/elasticsearch",
        "stdio"
      ],
      "env": {
        "ES_URL": "<your-elasticsearch-cluster-url>",
        "ES_API_KEY": "<your-elasticsearch-api-key>"
      }
    }
  }
}

Requires Docker to be installed and running.
