Signature MCP

Signature MCP lets your AI agent ask you for a signature. When a contract, offer or form needs signing, a window opens on your Mac: you see the document, draw your signature and confirm. Your agent gets the signed PDF back and carries on.

NOTHING IS SIGNED WITHOUT YOU Every request opens a window that names the AI app, says what it's for and shows the document. You draw the signature each time and click Sign. If you cancel, your agent is told you didn't sign.

SIGN ON THE DOCUMENT • See the whole PDF: scroll through the pages and pinch to zoom • Draw your signature on the trackpad without pressing, or with the mouse • Drag the signature to where it belongs, on any page • Signature MCP writes it into the PDF, so your agent doesn't have to place anything • Sign several documents in one window with one signature

FOR YOUR COMPANY • Add your name, role and company once; they're printed under the signature when you sign for the company • Add your company stamp from an image; a white background is removed • Your agent asks for them per document, and you can untick either one each time

DISPOSABLE BY DESIGN • A signature is drawn fresh for every request and never kept for reuse • The files your agent receives are deleted after ten minutes, and when the app quits • Your company stamp stays in the app; your agent only gets a temporary copy after you approve

WORKS WITH ANY AI AGENT Signature MCP is a Model Context Protocol (MCP) server that lives in your menu bar. Copy the setup prompt, paste it into your AI agent, and it connects itself. For apps that can't change their own settings, ready-made settings for popular AI apps are one click away.

PRIVATE • The server only listens on your Mac, and requests need your personal access token • No account, no tracking, no analytics. Signature MCP collects no data When your AI uses Signature MCP, the signed documents it receives go to your AI app's provider, just like anything else you share with it.

GOOD TO KNOW A signature drawn in Signature MCP is a simple electronic signature. Some documents need a handwritten or a qualified electronic signature instead, and a company stamp has no legal force of its own. Signature MCP doesn't check who signs and gives no legal advice; check what your document requires.

Requirements: an AI app that supports MCP servers.
