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 Api labz account to Claude via Composio Connect, enabling it to validate this IBAN before making payment, add a new deal record to CRM, list all Airtable tables in your project base, 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 Api labz account

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

For example, ask Claude to:

  • "Validate this IBAN before making payment"
  • "Add a new deal record to CRM"
  • "List all Airtable tables in your project base"

It will prompt you to authenticate and authorize access.

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

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

The Api labz MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Api labz account. It provides structured and secure access to a suite of AI-driven APIs, so your agent can validate IBANs, manage deals, search Trello boards, and retrieve Airtable tables on your behalf.

  • IBAN validation for finance workflows: Instantly check and verify international bank account numbers to ensure they are correctly formatted before processing transactions.
  • Automated deal integration: Seamlessly push new or updated deal records into your Api labz system, making it easy to automate CRM or sales processes.
  • AI-powered Trello board search: Leverage AI-driven queries to quickly find relevant Trello boards, lists, or cards, streamlining project management and task tracking.
  • Airtable table discovery: Effortlessly retrieve and list all tables within a specified Airtable base, enabling dynamic data access and management for your applications.

Troubleshooting

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

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

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

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

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

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

3. Why does the Api labz authorization link not work?

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

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

4. Why do Api labz actions fail after they worked before?

The Api labz connection can expire or lose permission.

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

5. How do I switch to a different Api labz account?

Claude can manage the Api labz connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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