Signpath is a code signing service that automates the secure signing of your software artifacts. It ensures authenticity and integrity for every release, right from your CI/CD pipeline.

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 Signpath account to Claude via Composio Connect, enabling it to list all available code signing certificates, show all projects for your organization, get details of current signing policies, 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 Signpath 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 Signpath account

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

For example, ask Claude to:

  • "List all available code signing certificates"
  • "Show all projects for your organization"
  • "Get details of current signing policies"

It will prompt you to authenticate and authorize access.

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

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

The Signpath MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Signpath account. It provides structured and secure access to your code signing workflows, so your agent can list certificates, retrieve project details, access signing policies, and check system metadata automatically on your behalf.

  • Certificate management and discovery: Quickly list all available code signing certificates within your organization, making it easy for your agent to select the right certificate for each workflow.
  • Automated project listing and tracking: Let your agent fetch and paginate through all Signpath projects, helping you organize, monitor, and automate signing across multiple software projects.
  • Signing policy insights and selection: Effortlessly retrieve detailed information about your organization’s signing policies, so your agent can ensure every artifact is signed according to security best practices.
  • System information and environment awareness: Instantly access Signpath system details, including product info, API version, and environment metadata, to keep your agent up to date with the latest platform capabilities.

Troubleshooting

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

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

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

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

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

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

3. Why does the Signpath authorization link not work?

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

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

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

The Signpath connection can expire or lose permission.

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

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

Claude can manage the Signpath connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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