Api Key

Starton is an all-in-one Web3 API platform for deploying and interacting with smart contracts, storing files on IPFS, and tracking blockchain events. It unifies Web3 operations for developers with a single, easy-to-use API.

6 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 Starton account to Claude via Composio Connect, enabling it to list all smart contracts in your project, upload this PDF to IPFS storage, show all blockchain event watchers, 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 Starton 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 Starton account

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

For example, ask Claude to:

  • "List all smart contracts in your project"
  • "Upload this PDF to IPFS storage"
  • "Show all blockchain event watchers"

It will prompt you to authenticate and authorize access.

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

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

The Starton MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Starton account. It provides structured and secure access to your Web3 projects, so your agent can perform actions like managing smart contracts, uploading files to IPFS, monitoring blockchain events, and handling webhooks on your behalf.

  • Smart contract management and discovery: Retrieve lists of your deployed or imported smart contracts, browse contract templates, and explore contract details for seamless project oversight.
  • Blockchain event monitoring: List, review, and manage watchers to keep tabs on critical blockchain events and get notified about on-chain activity relevant to your contracts.
  • IPFS file uploads: Effortlessly upload files to your project's IPFS storage, enabling decentralized file hosting directly from your agent.
  • Webhook oversight and configuration: Fetch and review all webhook watchers set up in your Starton project, making it simple to manage integrations and monitor workflows.
  • Event watcher lifecycle management: Retrieve, update, or delete specific smart contract event watchers by their ID, giving you fine-grained control over how your agent tracks blockchain activity.

Troubleshooting

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

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

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

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

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

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

3. Why does the Starton authorization link not work?

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

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

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

The Starton connection can expire or lose permission.

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

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

Claude can manage the Starton connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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