FAQ

OpenTelemetry MCP Server

Query and analyze LLM traces with AI assistance. Ask Claude to find expensive API calls, debug errors, compare model performance, or track token usage—all from your IDE.

An MCP (Model Context Protocol) server that connects AI assistants to OpenTelemetry trace backends (Jaeger, Tempo, Traceloop), with specialized support for LLM observability through OpenLLMetry semantic conventions.

Quick Start

No installation required! Configure your client to run the server directly from PyPI:

// Add to claude_desktop_config.json:
{
  "mcpServers": {
    "opentelemetry-mcp": {
      "command": "pipx",
      "args": ["run", "opentelemetry-mcp"],
      "env": {
        "BACKEND_TYPE": "jaeger",
        "BACKEND_URL": "http://localhost:16686"
      }
    }
  }
}

Or use uvx (alternative):

{
  "mcpServers": {
    "opentelemetry-mcp": {
      "command": "uvx",
      "args": ["opentelemetry-mcp"],
      "env": {
        "BACKEND_TYPE": "jaeger",
        "BACKEND_URL": "http://localhost:16686"
      }
    }
  }
}

That's it! Ask Claude: "Show me traces with errors from the last hour"

Installation

For End Users (Recommended)

# Run without installing (recommended)
pipx run opentelemetry-mcp --backend jaeger --url http://localhost:16686

# Or with uvx
uvx opentelemetry-mcp --backend jaeger --url http://localhost:16686

This approach:

✅ Always uses the latest version
✅ No global installation needed
✅ Isolated environment automatically
✅ Works on all platforms

Per Client Integration

Configure the MCP server in your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Using pipx (recommended):

{
  "mcpServers": {
    "opentelemetry-mcp": {
      "command": "pipx",
      "args": ["run", "opentelemetry-mcp"],
      "env": {
        "BACKEND_TYPE": "jaeger",
        "BACKEND_URL": "http://localhost:16686"
      }
    }
  }
}

Using uvx (alternative):

{
  "mcpServers": {
    "opentelemetry-mcp": {
      "command": "uvx",
      "args": ["opentelemetry-mcp"],
      "env": {
        "BACKEND_TYPE": "jaeger",
        "BACKEND_URL": "http://localhost:16686"
      }
    }
  }
}

For Traceloop backend:

{
  "mcpServers": {
    "opentelemetry-mcp": {
      "command": "pipx",
      "args": ["run", "opentelemetry-mcp"],
      "env": {
        "BACKEND_TYPE": "traceloop",
        "BACKEND_URL": "https://api.traceloop.com",
        "BACKEND_API_KEY": "your_traceloop_api_key_here"
      }
    }
  }
}

If you're developing locally with the cloned repository, use one of these configurations:

Option 1: Wrapper script (easy backend switching)

{
  "mcpServers": {
    "opentelemetry-mcp": {
      "command": "/absolute/path/to/opentelemetry-mcp-server/start_locally.sh"
    }
  }
}

Option 2: UV directly (for multiple backends)

{
  "mcpServers": {
    "opentelemetry-mcp-jaeger": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/opentelemetry-mcp-server",
        "run",
        "opentelemetry-mcp"
      ],
      "env": {
        "BACKEND_TYPE": "jaeger",
        "BACKEND_URL": "http://localhost:16686"
      }
    }
  }
}

Claude Code works with MCP servers configured in your Claude Desktop config. Once configured above, you can use the server with Claude Code CLI:

# Verify the server is available
claude-code mcp list

# Use Claude Code with access to your OpenTelemetry traces
claude-code "Show me traces with errors from the last hour"

Configure the MCP server in your Gemini CLI config file (~/.gemini/config.json):

Using pipx (recommended):

{
  "mcpServers": {
    "opentelemetry-mcp": {
      "command": "pipx",
      "args": ["run", "opentelemetry-mcp"],
      "env": {
        "BACKEND_TYPE": "jaeger",
        "BACKEND_URL": "http://localhost:16686"
      }
    }
  }

        "BACKEND_TYPE": "jaeger",
        "BACKEND_URL": "http://localhost:16686"
      }
    }
  }
}

Then use Gemini CLI with your traces:

gemini "Analyze token usage for gpt-4 requests today"

{
  "mcpServers": {
    "opentelemetry-mcp": {
      "command": "uv",
      "args": [

      ],
      "env": {
        "BACKEND_TYPE": "jaeger",
        "BACKEND_URL": "http://localhost:16686"
      }
    }

BACKEND_TIMEOUT=30

# Optional: Logging level
LOG_LEVEL=INFO

Jaeger

BACKEND_TYPE=jaeger
BACKEND_URL=http://localhost:16686

Grafana Tempo

BACKEND_TYPE=tempo
BACKEND_URL=http://localhost:3200

Traceloop

BACKEND_TYPE=traceloop
BACKEND_URL=https://api.traceloop.com
BACKEND_API_KEY=your_api_key_here

Note: The API key contains project information. The backend uses a project slug of "default" and Traceloop resolves the actual project/environment from the API key.

Usage

Quick Start with start_locally.sh (Recommended)

The easiest way to run the server:

./start_locally.sh

This script handles all configuration and starts the server in stdio mode (perfect for Claude Desktop integration). To switch backends, simply edit the script and uncomment your preferred backend.

Manual Running

For advanced use cases or custom configurations, you can run the server manually.

stdio Transport (for Claude Desktop)

Start the MCP server with stdio transport for local/Claude Desktop integration:

# If installed with pipx/pip
opentelemetry-mcp

# If running from cloned repository with UV
uv run opentelemetry-mcp

# With backend override (pipx/pip)
opentelemetry-mcp --backend jaeger --url http://localhost:16686

# With backend override (UV)
uv run opentelemetry-mcp --backend jaeger --url http://localhost:16686

HTTP Transport (for Network Access)

Start the MCP server with HTTP/SSE transport for remote access:

# If installed with pipx/pip
opentelemetry-mcp --transport http

# If running from cloned repository with UV
uv run opentelemetry-mcp --transport http

# Specify custom host and port (pipx/pip)
opentelemetry-mcp --transport http --host 127.0.0.1 --port 9000

# With UV
uv run opentelemetry-mcp --transport http --host 127.0.0.1 --port 9000

The HTTP server will be accessible at http://localhost:8000/sse by default.

Transport Use Cases:

stdio transport: Local use, Claude Desktop integration, single process
HTTP transport: Remote access, multiple clients, network deployment, sample applications

Analyze by model:

Use get_llm_usage to see which models are costing the most

Investigate specific traces:

Use get_trace with the trace_id to see exact prompts/responses

Performance Debugging

Find slow operations:

Use get_llm_slow_traces to identify latency issues

Check for errors:

Use find_errors to see failure patterns

Analyze finish reasons:

Use get_llm_model_stats to see if responses are being truncated

Model Adoption Tracking

Discover models in use:

Use list_llm_models to see all models being called

Compare model statistics:

Use get_llm_model_stats for each model to compare performance
