PenlyDoc MCP server

Let an AI assistant send documents for e-signature with PenlyDoc and follow them: "Send the lease to Mia Novak from the Residential lease template, rent 950 EUR", "Who still has to sign order 42?", "Save the signed contract to ./signed".

It is a Model Context Protocol server that runs on your computer (stdio) and talks to the PenlyDoc REST API with your organisation's API key. Works with any MCP client.

Setup

  1. Create an organisation at penlydoc.com (free) and copy an API key from Console → Developers.
  2. Add the server to your MCP client's configuration:
{
  "mcpServers": {
    "penlydoc": {
      "command": "npx",
      "args": ["-y", "penlydoc-mcp"],
      "env": { "PENLY_API_KEY": "sk_…" }
    }
  }
}

Node.js 18.17 or newer is needed. PENLY_URL points the server at another PenlyDoc instance (default https://penlydoc.com).

Treat the API key like a password: it can send documents in your organisation's name. Give the assistant a key of its own, so you can revoke it in the console without touching your other integrations.

The server tells the assistant to confirm people, e-mail addresses and documents with you before anything is sent. Most MCP clients also ask you before each tool call; keep that on for the tools that e-mail people.
