Propper AI Launches Open-Source Claude Plugin for Agreement Preparation and Tracking

The open-source bundle from Propper AI gives your assistant 13 skills for preparing documents, sending agreements for signature, and checking statuses after.

PropperDocs, Inc. (Propper AI) today announced the release of the Propper plugin for Claude Code and Claude Cowork. The plugin has passed Anthropic’s plugin review and is available as an open-source bundle of 13 skills under the Apache 2.0 license.

Agreement work breaks down in the gaps between systems, the blank nobody caught, the signer nobody chased. These skills put that work where people are already working.”

— Jack Berube, Founder and CEO

The bundle gives an AI assistant packaged instructions for preparing documents, sending agreements for signature, and tracking what happens after they go out. Users can start with a contract they already have, asking Claude to find unfilled blanks, compare a returned version clause by clause, or extract renewal and notice dates, and connect a Propper account when they are ready to create drafts, place signature fields, route agreements, and check who still needs to sign.

“Agreement work breaks down in the gaps between systems, the blank nobody caught, the signer nobody chased,” said Jack Berube, Founder and CEO of Propper AI. “These skills put that work where people are already working, with a stop-and-confirm step before anything is sent.”

What the skills cover.

The 13 skills span five kinds of work: checking a document before it leaves your desk; generating recurring documents from templates with Propper Gen; creating drafts, adding recipients, and placing fields with Propper Sign; tracking recipient progress and retrieving completed documents; and auditing a DocuSign^® template export or building embedded signing into your own application. Eleven skills handle tasks directly, while two shared skills supply the authentication, recipient-role, and confirmation instructions the others rely on.

Several tasks require no Propper account at all. Local document checks, version comparisons, date extraction, template-export audits, and the included nine-template starter pack, covering mutual and unilateral NDAs, a consulting agreement, a statement of work, and an employment offer letter, all work before connecting.

“I spent years watching agreements move through systems that could store a contract but couldn’t reason about one,” said Grant Peterson, Chief Strategy Officer at Propper and former Chief Technology Officer of Docusign. “What excites me here is where this lands us. Preparation, execution, and tracking are the center of intelligent agreement management, and these skills put Propper squarely in the middle of that workflow rather than at the end of it. Thirteen skills is a starting position, not a finish line, we are just getting started!”

Built on the Model Context Protocol

Propper shipped Model Context Protocol (MCP) support in March 2026. This release adds the packaged workflow instructions on top of it. The connection uses OAuth 2.0 with PKCE, so users authenticate through the browser rather than pasting credentials into a conversation. Permissions are split by action, separate scopes govern reading agreements, editing drafts, and sending or voiding them, and the skills instruct the assistant to request explicit confirmation before any send, void, or delete.
