Api Key

Arize AX is an AI engineering platform for tracing, evaluating, and improving AI applications. Use it to debug LLM behavior, compare experiments, and improve production AI quality.

24 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Arize AX account to Claude via Composio Connect, enabling it to summarize failed spans from latest traces, compare experiment results across prompt versions, create dataset from production traces, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting Arize AX to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Arize AX account

Back in Claude, ask it to connect to Arize AX or give it any Arize AX-related task.

For example, ask Claude to:

  • "Summarize failed spans from latest traces"
  • "Compare experiment results across prompt versions"
  • "Create dataset from production traces"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Arize AX account is ready to use.

What is the Arize AX Claude Connector, and what's possible with it?

The Arize AX MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Arize AX account. It provides structured and secure access so your agent can perform Arize AX operations on your behalf.

Troubleshooting

1. Why does Claude not use the Composio connector for Arize AX?

The connector can show as connected, but Claude must use it in each Arize AX conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Arize AX again.

2. Why does Claude show an MCP server error before Arize AX connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Arize AX.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Arize AX.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Arize AX authorization link not work?

The Composio connector is one server. Your Arize AX account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Arize AX connection.
  • Composio creates a fresh Arize AX authorization link.
  • Open that link in your browser and finish the Arize AX sign-in.

4. Why do Arize AX actions fail after they worked before?

The Arize AX connection can expire or lose permission.

  • Ask Claude to inspect the Arize AX connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Arize AX account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Arize AX.
  • If the action still fails with a permission error, check that the connected account has that permission in Arize AX itself.

5. How do I switch to a different Arize AX account?

Claude can manage the Arize AX connection for you.

  • Ask Claude to disconnect or delete the current Arize AX account.
  • Ask Claude to connect Arize AX again.
  • Open the new Composio authorization link for Arize AX.
  • Sign in with the other Arize AX account in the browser.
  • After the account connects, ask Claude to retry the Arize AX task.

6. Why is my Arize AX connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Arize AX connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Arize AX tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Arize AX.

FAQ

Frequently asked questions

With a standalone Arize AX MCP server, the agents and LLMs can only access a fixed set of Arize AX tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Arize AX and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Arize AX tools.

Yes, absolutely. You can configure which Arize AX scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Arize AX data and credentials are handled as safely as possible.
