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 Sanity account to Claude via Composio Connect, enabling it to list recent Sanity posts needing review, create draft product page in Sanity, update author bio across Sanity articles, 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.

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 Sanity account

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

For example, ask Claude to:

  • "List recent Sanity posts needing review"
  • "Create draft product page in Sanity"
  • "Update author bio across Sanity articles"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Sanity authorization link not work?

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

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

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

The Sanity connection can expire or lose permission.

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

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

Claude can manage the Sanity connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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