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 Knack account to Claude via Composio Connect, enabling it to find all overdue tasks in Knack, create a new project record, update status for order #1023 to shipped, 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.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Knack account

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

For example, ask Claude to:

  • "Find all overdue tasks in Knack"
  • "Create a new project record"
  • "Update status for order #1023 to shipped"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Knack authorization link not work?

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

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

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

The Knack connection can expire or lose permission.

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

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

Claude can manage the Knack connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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