Freeagent is a cloud-based accounting platform designed for freelancers and small businesses. It simplifies bookkeeping, invoicing, and expense management in one place.

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 Freeagent account to Claude via Composio Connect, enabling it to list overdue invoices for this month, create a new expense for office supplies, summarize all unassigned transactions, 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.

3. Connect your Freeagent account

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

For example, ask Claude to:

  • "List overdue invoices for this month"
  • "Create a new expense for office supplies"
  • "Summarize all unassigned transactions"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Freeagent authorization link not work?

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

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

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

The Freeagent connection can expire or lose permission.

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

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

Claude can manage the Freeagent connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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