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 Parseur account to Claude via Composio Connect, enabling it to list all documents in your invoices mailbox, create a webhook to send parsed receipts, pause the outgoing webhook for orders mailbox, 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 Parseur 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 Parseur account

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

For example, ask Claude to:

  • "List all documents in your invoices mailbox"
  • "Create a webhook to send parsed receipts"
  • "Pause the outgoing webhook for orders mailbox"

It will prompt you to authenticate and authorize access.

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

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

The Parseur MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Parseur account. It provides structured and secure access to your Parseur data extraction workflows, so your agent can perform actions like managing mailboxes, handling documents, configuring webhooks, and automating template operations on your behalf.

  • Mailbox management and discovery: Let your agent list, browse, and filter all Parseur mailboxes to keep tabs on your parsing operations and document streams.
  • Document listing and retrieval: Effortlessly fetch documents from specific mailboxes, enabling automated sorting, searching, or pagination of your parsed files.
  • Template and parsing rule automation: Ask your agent to list templates within any mailbox, so you can quickly inspect or update parsing rules as your data extraction needs evolve.
  • Webhook configuration and control: Enable your agent to create, update, pause, enable, or delete webhooks, making it easy to automate real-time data delivery to your other systems.
  • Comprehensive webhook inspection: Retrieve detailed webhook information or list all webhooks for a mailbox, ensuring you always know how and where your parsed data is flowing.

Troubleshooting

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

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

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

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

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

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

3. Why does the Parseur authorization link not work?

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

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

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

The Parseur connection can expire or lose permission.

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

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

Claude can manage the Parseur connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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