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 Bigpicture io account to Claude via Composio Connect, enabling it to find company details for apple.com, identify companies using this IP address, suggest domains for 'Acme Corporation', 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 Bigpicture io account

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

For example, ask Claude to:

  • "Find company details for apple.com"
  • "Identify companies using this IP address"
  • "Suggest domains for 'Acme Corporation'"

It will prompt you to authenticate and authorize access.

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

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

The Bigpicture io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bigpicture io account. It provides structured and secure access to comprehensive company and domain data, so your agent can perform actions like finding company profiles, mapping company names to domains, and discovering company info from IP addresses—all on your behalf.

  • Company domain lookup by name: Instantly find up to three likely company domains when you provide a business name, making it easy to identify and validate organizations.
  • Detailed company profile by website domain: Retrieve rich and up-to-date company information by specifying a company's website domain, perfect for enrichment or qualification workflows.
  • IP address to company matching: Uncover the company behind any IP address, helping with cybersecurity, analytics, or lead identification tasks.
  • Data enrichment for sales and marketing: Supercharge your prospecting and market research by letting your agent fetch background details for millions of businesses.

Troubleshooting

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

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

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

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

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

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

3. Why does the Bigpicture io authorization link not work?

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

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

4. Why do Bigpicture io actions fail after they worked before?

The Bigpicture io connection can expire or lose permission.

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

5. How do I switch to a different Bigpicture io account?

Claude can manage the Bigpicture io connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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