Xata is a serverless, scalable, branchable cloud database platform. It streamlines modern app development with hassle-free, developer-focused data management.

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 Xata account to Claude via Composio Connect, enabling it to list all records from the customers table, insert a new order with status pending, update the email field for customer 101, 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.

Add to Claude

Add manually

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

3. Connect your Xata account

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

For example, ask Claude to:

  • "List all records from the customers table."
  • "Insert a new order with status pending."
  • "Update the email field for customer 101."

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

  • 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 Xata.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Xata authorization link not work?

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

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

4. Why do Xata actions fail after they worked before?

The Xata connection can expire or lose permission.

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

5. How do I switch to a different Xata account?

Claude can manage the Xata connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Xata 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 Xata.

FAQ

Frequently asked questions

With a standalone Xata MCP server, the agents and LLMs can only access a fixed set of Xata tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Xata 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 Xata tools.

Yes, absolutely. You can configure which Xata 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 Xata data and credentials are handled as safely as possible.
