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 Documenso account to Claude via Composio Connect, enabling it to send a contract to client for signature, download the latest signed NDA document, list all templates for onboarding paperwork, 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 Documenso account

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

For example, ask Claude to:

  • "Send a contract to client for signature"
  • "Download the latest signed NDA document"
  • "List all templates for onboarding paperwork"

It will prompt you to authenticate and authorize access.

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

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

The Documenso MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Documenso account. It provides structured and secure access to your electronic signature workflows, so your agent can create documents, distribute them for signing, manage templates, and download signed files automatically on your behalf.

  • Automated document creation and duplication: Prompt your agent to generate new documents or make exact copies of existing ones for rapid workflow setup.
  • Seamless document distribution for signatures: Let your agent send documents to one or more recipients, kicking off secure e-signature flows without manual intervention.
  • Template management and retrieval: Ask your agent to list, fetch, or delete document templates, keeping your signing processes organized and up-to-date.
  • Download and access signed documents: Have your agent retrieve finalized, signed PDFs automatically for seamless archiving or sharing.
  • Streamlined document organization: Direct your agent to move documents between personal and team spaces, or remove unnecessary fields to keep everything tidy and current.

Troubleshooting

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

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

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

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

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

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

3. Why does the Documenso authorization link not work?

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

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

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

The Documenso connection can expire or lose permission.

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

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

Claude can manage the Documenso connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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