Api Key

Smartproxy is a robust proxy and web scraping platform offering residential, datacenter, ISP, and mobile proxies plus scraping APIs. It enables fast, reliable, and scalable access to public web data for developers and businesses.

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 Smartproxy account to Claude via Composio Connect, enabling it to show all available proxy endpoints, list residential proxy ports right now, how do I get your Smartproxy API key?, 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 Smartproxy 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 Smartproxy account

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

For example, ask Claude to:

  • "Show all available proxy endpoints"
  • "List residential proxy ports right now"
  • "How do I get your Smartproxy API key?"

It will prompt you to authenticate and authorize access.

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

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

The Smartproxy MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Smartproxy account. It provides structured and secure access to your proxy network and scraping tools, so your agent can perform actions like listing proxy endpoints, managing ports, and guiding you through API key setup—streamlining automated data collection and proxy management.

  • Proxy endpoint discovery: Instantly fetch a comprehensive list of all available proxy endpoints and their corresponding ports for streamlined integration into your workflows.
  • Automated proxy inventory management: Let your agent help you view and organize the full range of Smartproxy’s residential, datacenter, ISP, and mobile proxies—making it easy to select the right resource for any task.
  • Guided API key setup: Ask your agent to walk you through the steps to obtain or manage your Smartproxy API key, ensuring seamless authentication for all automated actions.
  • Centralized proxy access for scraping: Enable your AI agent to leverage Smartproxy’s infrastructure for web scraping and data collection, all while managing endpoints securely.

Troubleshooting

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

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

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

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

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

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

3. Why does the Smartproxy authorization link not work?

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

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

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

The Smartproxy connection can expire or lose permission.

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

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

Claude can manage the Smartproxy connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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