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 Basin account to Claude via Composio Connect, enabling it to create a new form for event signups, delete an old feedback form from project, get details of your contact form, 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 Basin account

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

For example, ask Claude to:

  • "Create a new form for event signups"
  • "Delete an old feedback form from project"
  • "Get details of your contact form"

It will prompt you to authenticate and authorize access.

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

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

The Basin MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Basin account. It provides structured and secure access to your projects, forms, submissions, domains, and webhooks, so your agent can create forms, manage projects, review submissions, configure webhooks, and inspect form activity on your behalf.

  • Project and form management: Have your agent create, update, list, inspect, or delete Basin projects and forms.
  • Submission review and cleanup: Instruct your agent to search, filter, sort, review, and permanently delete form submissions.
  • Webhook configuration: Let the agent create, inspect, update, list, or delete webhooks associated with your forms.
  • Form configuration and activity: Direct your agent to retrieve form settings, notification and security options, branding details, submission counts, and form views.
  • Custom domain lookup: Have your agent list the custom domains associated with your Basin account.

Troubleshooting

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

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

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

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

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

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

3. Why does the Basin authorization link not work?

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

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

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

The Basin connection can expire or lose permission.

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

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

Claude can manage the Basin connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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