ONLYOFFICE DocSpace is a tenant-hosted document collaboration platform for rooms, files, folders, users, groups, sharing, and portal settings. It helps teams manage secure document workflows in one shared workspace.

10 Tools

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 ONLYOFFICE DocSpace account to Claude via Composio Connect, enabling it to list documents in project rooms, create folder for vendor contracts, share finance room with auditors, 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 ONLYOFFICE DocSpace account

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

For example, ask Claude to:

  • "List documents in project rooms"
  • "Create folder for vendor contracts"
  • "Share finance room with auditors"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the ONLYOFFICE DocSpace authorization link not work?

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

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

4. Why do ONLYOFFICE DocSpace actions fail after they worked before?

The ONLYOFFICE DocSpace connection can expire or lose permission.

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

5. How do I switch to a different ONLYOFFICE DocSpace account?

Claude can manage the ONLYOFFICE DocSpace connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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