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 PayChasers account to Claude via Composio Connect, enabling it to send payment reminder for invoice INV-123, list overdue invoices older than 30 days, create follow-up sequence for overdue accounts, 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.

For example, ask Claude to:

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the PayChasers authorization link not work?

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

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

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

The PayChasers connection can expire or lose permission.

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

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

Claude can manage the PayChasers connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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