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 Signaturely account to Claude via Composio Connect, enabling it to show all documents I sent for signature, list templates for non-disclosure agreements, find signed contracts from last month, 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 Signaturely account

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

For example, ask Claude to:

  • "Show all documents I sent for signature"
  • "List templates for non-disclosure agreements"
  • "Find signed contracts from last month"

It will prompt you to authenticate and authorize access.

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

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

The Signaturely MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Signaturely account. It provides structured and secure access to your Signaturely workspace, so your agent can perform actions like listing documents, retrieving templates, managing agreements, and streamlining your signature workflows on your behalf.

  • Comprehensive document retrieval: Quickly list and view all documents in your Signaturely account, making it easy to track agreements, contracts, and signed files.
  • Template management: Let your agent fetch and organize reusable document templates, streamlining the process of preparing new signature requests.
  • Automated document discovery: Effortlessly filter and search for specific documents based on status, type, or other criteria, so you always find what you need.
  • Workflow optimization: Use AI to surface relevant templates or documents for various business scenarios, helping you automate signature processes and reduce manual work.

Troubleshooting

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

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

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

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

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

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

3. Why does the Signaturely authorization link not work?

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

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

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

The Signaturely connection can expire or lose permission.

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

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

Claude can manage the Signaturely connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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