Api Key

Retable is a collaborative spreadsheet and database platform for organizing workspaces, tables, and files. Use it to manage projects, structure data, and collaborate with teammates in flexible tables.

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 Retable account to Claude via Composio Connect, enabling it to list all tables in Marketing workspace, create a new row in Campaigns, upload file to Campaigns table row 12, 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.

3. Connect your Retable account

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

For example, ask Claude to:

  • "List all tables in Marketing workspace"
  • "Create a new row in Campaigns"
  • "Upload file to Campaigns table row 12"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Retable authorization link not work?

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

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

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

The Retable connection can expire or lose permission.

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

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

Claude can manage the Retable connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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