Api Key

0CodeKit is a utility API platform for AI, document, image, and data workflows. Use it to convert, validate, generate, store, and automate data without custom backend code.

8 Tools

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 0CodeKit account to Claude via Composio Connect, enabling it to convert JSON data into CSV file, generate QR code for checkout link, extract text from uploaded PDF, 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.

Connecting 0CodeKit to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

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

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

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 0CodeKit account

Back in Claude, ask it to connect to 0CodeKit or give it any 0CodeKit-related task.

For example, ask Claude to:

  • "Convert JSON data into CSV file"
  • "Generate QR code for checkout link"
  • "Extract text from uploaded PDF"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your 0CodeKit account is ready to use.

What is the 0CodeKit Claude Connector, and what's possible with it?

The 0CodeKit MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your 0CodeKit account. It provides structured and secure access so your agent can perform 0CodeKit operations on your behalf.

Troubleshooting

1. Why does Claude not use the Composio connector for 0CodeKit?

The connector can show as connected, but Claude must use it in each 0CodeKit conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to 0CodeKit again.

2. Why does Claude show an MCP server error before 0CodeKit connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for 0CodeKit.

  • 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 0CodeKit.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the 0CodeKit authorization link not work?

The Composio connector is one server. Your 0CodeKit account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the 0CodeKit connection.
  • Composio creates a fresh 0CodeKit authorization link.
  • Open that link in your browser and finish the 0CodeKit sign-in.

4. Why do 0CodeKit actions fail after they worked before?

The 0CodeKit connection can expire or lose permission.

  • Ask Claude to inspect the 0CodeKit connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the 0CodeKit account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in 0CodeKit.
  • If the action still fails with a permission error, check that the connected account has that permission in 0CodeKit itself.

5. How do I switch to a different 0CodeKit account?

Claude can manage the 0CodeKit connection for you.

  • Ask Claude to disconnect or delete the current 0CodeKit account.
  • Ask Claude to connect 0CodeKit again.
  • Open the new Composio authorization link for 0CodeKit.
  • Sign in with the other 0CodeKit account in the browser.
  • After the account connects, ask Claude to retry the 0CodeKit task.

6. Why is my 0CodeKit connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your 0CodeKit connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If 0CodeKit 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 0CodeKit.

FAQ

Frequently asked questions

With a standalone 0CodeKit MCP server, the agents and LLMs can only access a fixed set of 0CodeKit tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from 0CodeKit 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 0CodeKit tools.

Yes, absolutely. You can configure which 0CodeKit 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 0CodeKit data and credentials are handled as safely as possible.
