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 Onepage account to Claude via Composio Connect, enabling it to search for companies in the fintech sector, find user profiles mentioning 'AI research', get details for your current API token, 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 Onepage account

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

For example, ask Claude to:

  • "Search for companies in the fintech sector"
  • "Find user profiles mentioning 'AI research'"
  • "Get details for your current API token"

It will prompt you to authenticate and authorize access.

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

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

The Onepage MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Onepage account. It provides structured and secure access to your Onepage data, so your agent can perform actions like running advanced searches, retrieving content, validating tokens, and managing access metadata on your behalf.

  • Advanced content and user search: Let your agent search across all available user and company data within Onepage, using custom queries, filters, and output formats.
  • Detailed token validation: Have your agent check the status, permissions, and expiration details of any Onepage token to ensure secure and compliant workflows.
  • Customizable language and output: Enable your agent to tailor search results by language preference and choose between structured JSON or plain text formats for seamless integration.
  • Metadata retrieval for audit and compliance: Automatically fetch comprehensive token metadata to support security audits and access reviews within your organization.

Troubleshooting

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

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

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

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

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

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

3. Why does the Onepage authorization link not work?

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

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

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

The Onepage connection can expire or lose permission.

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

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

Claude can manage the Onepage connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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