Open-source legal template filling CLI and library

OpenAgreements

English | Español | 简体中文 | Português (Brasil) | Deutsch

Fill standard legal agreement templates and get signable DOCX files. OpenAgreements includes 40+ templates across NDAs, cloud service agreements, employment docs, contractor agreements, SAFEs, and NVCA financing documents.

Works with Claude Code, Gemini CLI, Cursor, and local MCP or CLI workflows.

Who this is for

OpenAgreements starts with standard forms teams already recognize: Common Paper, Bonterms, NVCA model documents, and YC SAFE templates. It is for small-business legal teams, founders, and the agents helping them who need repeatable agreement filling with source, license, and validation context kept close to the document.

Demo: Claude fills a Common Paper Mutual NDA in under 2 minutes. Sped up for brevity.

Cursor

This repository includes a Cursor plugin manifest at .cursor-plugin/plugin.json with MCP wiring in mcp.json.

Local Vs Hosted Execution

Local: npx, global install, or stdio MCP. Processing happens on your machine.
Hosted: https://openagreements.org/api/mcp. Template filling runs server-side for faster setup.

Choose based on document sensitivity and internal policy. See the trust checklist below for the data-flow summary.

Quick Start

With Claude Code

Ask Claude:

Fill the Common Paper mutual NDA for my company

Claude can discover templates, interview you for field values, and render a signed-ready DOCX.

With the CLI

# See all available templates
open-agreements list

# Fill a template from a JSON data file
open-agreements fill common-paper-mutual-nda -d values.json -o my-nda.docx

# Fill with inline values
open-agreements fill common-paper-mutual-nda --set party_1_name="Acme Corp" --set governing_law="Delaware"

Example Prompts

"Draft an NDA for our construction subcontractor"
"Create a consulting agreement for our insurance agency"
"Fill the independent contractor agreement for a freelance designer"
"Generate a SAFE with a $5M valuation cap"

What Happens

The agent runs list --json to discover templates and their fields.
It interviews you for field values grouped by section.
It runs fill <template> to render a DOCX preserving the source formatting.
You review and sign the output document.
