## 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 Polar account to Claude via Composio Connect, enabling it to list all products in your Polar account, review active Polar subscriptions this month, show recent Polar orders and customer details, 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.

## What is the Polar MCP server, and what's possible with it?

The Polar MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Polar account. It provides structured and secure access to Polar's merchant-of-record tools, so your agent can create products and checkout sessions, manage customers and subscriptions, issue refunds, and handle customer portal and licensing tasks on your behalf.
- Products and checkout management: Have your agent create products, checkout sessions, checkout links, discounts, and customer orders for your Polar storefront.
- Customer and subscription operations: Let the agent create customers, add customer members, create subscriptions, cancel portal subscriptions, and manage customer payment methods.
- Benefits and license keys: Direct your agent to create benefits such as license keys or file downloads, activate or deactivate license key instances, and manage customer seats.
- Payments, refunds, and disputes: Instruct your agent to create refunds, accept disputes, retry customer payments, or create orders for off-session charges against saved payment methods.
- Account configuration and reporting: Have your agent create organizations, custom fields, files, meters, metric dashboards, and webhook endpoints for your Polar operations.

## Troubleshooting

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

The connector can show as connected, but Claude must use it in each Polar conversation.
- Click + at the lower left of the chat, or type /.
- Hover Connectors.
- Turn on Composio.
- Ask Claude to connect to Polar again.

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

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Polar.
- 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 Polar.
- If it fails again, send the error and the ofid_ reference id to support@composio.dev.

### 3. Why does the Polar authorization link not work?

The Composio connector is one server. Your Polar account connects separately when Claude asks for it.
- If the browser does not open, or the link expires, ask Claude to retry the Polar connection.
- Composio creates a fresh Polar authorization link.
- Open that link in your browser and finish the Polar sign-in.

### 4. Why do Polar actions fail after they worked before?

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

### 5. How do I switch to a different Polar account?

Claude can manage the Polar connection for you.
- Ask Claude to disconnect or delete the current Polar account.
- Ask Claude to connect Polar again.
- Open the new Composio authorization link for Polar.
- Sign in with the other Polar account in the browser.
- After the account connects, ask Claude to retry the Polar task.

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

The connector belongs to your Claude account, so your Polar connection works in Claude Web, Desktop, and Cowork.
- In Claude Desktop, open Customize > Connectors.
- Next to Composio, click ⋮ and click Clear cache.
- If Polar 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 Polar.

## Creating MCP Server - Stand-alone vs Composio SDK

The Polar MCP server connects Claude Web, Desktop, and Cowork to your Polar account through Composio. Once connected, Claude can use the available Polar tools and triggers to complete tasks on your behalf.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Polar MCP?

With a standalone Polar MCP server, the agents and LLMs can only access a fixed set of Polar tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Polar and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

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 Polar tools.

### Can I manage the permissions and scopes for Polar while using Tool Router?

Yes, absolutely. You can configure which Polar 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.

### How safe is my data with Composio Tool Router?

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 Polar data and credentials are handled as safely as possible.
