Common questions

Is Signforge safe?

It passed 1 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SIGNFORGE_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 7 months ago, and the latest version (1.2.2) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@signforge/mcp-server

Send documents for e-signature directly from Claude Desktop, Claude Code, Cursor, and other AI agents — powered by SignForge, the free e-signature platform.

What It Does

This MCP server connects AI agents to SignForge's e-signature API. Your AI assistant can:

Send documents for signature — upload a PDF, specify a signer, and send in one step
Manage envelopes — send, void, delete, and check status
Download documents — signed PDFs, audit certificates, and ZIP archives
Use templates — create envelopes from reusable templates with pre-filled fields
Manage webhooks — subscribe to real-time envelope events
Generate embed URLs — create embeddable signing experiences

Quick Start

1. Get Your API Key

2. Configure Your AI Client

Choose your client below and add the configuration:

Claude Desktop

Add to your claude_desktop_config.json:

"mcpServers": { "signforge": { "command": "npx", "args": ["-y", "@signforge/mcp-server"], "env": { "SIGNFORGE_API_KEY": "your-api-key-here" } } } }

Config file location:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Claude Code

claude mcp add signforge -- npx -y @signforge/mcp-server

Then set the environment variable in your shell:

export SIGNFORGE_API_KEY="your-api-key-here"
