• Use curated tracing examples and best practices

• Direct connection to Arize support through natural language queries

Installation

The Arize Tracing Assistant is distributed via uv, a fast Python package manager.

Manual MCP Config

Add this snippet to your mcpServers config section:

"mcpServers": {
  "arize-tracing-assistant": {
    "command": "uvx",
    "args": ["arize-tracing-assistant@latest"]
  }
}

Usage

Once the MCP server is running, you can ask your IDE or LLM natural-language questions like:

• “Instrument this app using Arize.”

• “Can you use manual instrumentation so that I have more control over my traces?”

• “How can I redact sensitive information from my spans?”

• “Can you make sure the context of this trace is propagated across these tool calls?”

• “Where can I find my Arize keys?”

Troubleshooting

• Ensure your JSON configs are properly formatted

• Run uv cache clean to reset any cached versions

• Confirm the uv path using:

  which uv

• Start the server manually by running:

  uvx arize-tracing-assistant@latest

• Use Anthropic's MCP inspector:

  npx @modelcontextprotocol/inspector uvx arize-tracing-assistant@latest
