What is MCP?

MCP (Model Context Protocol) is an open standard that lets AI assistants connect to external tools. Instead of copy-pasting document links or manually checking signature status, your AI does it all — directly from the chat.

Before MCP

Manual copy-paste hell. Navigating menus, downloading PDFs, and tracking statuses across multiple browser tabs.

Recommended

With MCP

Natural language workflow. "Send the NDA", "Is it signed yet?", "Invite John". Your AI assistant executes instantly.

Frequently Asked Questions

What is an MCP server?

MCP (Model Context Protocol) is an open-standard protocol designed to allow AI models to interact with external tools, APIs, and data sources securely. Zignature's MCP server exposes 57 specific document and contract management tools to your favorite AI assistant.

Does Zignature support MCP?

Yes, Zignature is a first-class citizen in the MCP ecosystem. We provide a fully featured MCP server that works across all major MCP-compatible clients like Claude, Cursor, and Windsurf.

How do I connect Claude to Zignature?

For Claude.ai web, go to Settings → Integrations → Add Custom Integration and paste our MCP URL. For Claude Desktop, you'll need to add our server configuration to your `claude_desktop_config.json` file. See our Claude guide for details.

How do I connect ChatGPT to Zignature?

You can use Zignature with ChatGPT in two ways: by creating a Custom GPT and adding our API as an Action, or by using the ChatGPT Desktop app which now supports the Model Context Protocol directly.

Is the Zignature MCP server free?

Yes. Access to the MCP server is included in Zignature's free plan. You only need a free account to generate an API key and start connecting your AI assistants.

What documents can I sign via MCP?

Any template you've created or uploaded to Zignature can be triggered via MCP. This includes NDAs, MSAs, SOWs, employment contracts, and custom forms.

Is MCP secure? Does Zignature use OAuth?

Security is our priority. Zignature supports OAuth 2.0 with PKCE for remote web-based connections and secure API tokens (X-Auth-Token) for local desktop configurations.

What's the difference between API Token and OAuth authentication?

OAuth allows you to grant access to an AI service (like Claude.ai) by logging in with your Zignature credentials, without ever exposing your API key. API Tokens are static keys you generate in our Developer Portal, which are useful for local apps like Cursor where you manage your own configuration file.
