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

Fill standard legal agreement templates and get signable DOCX files. 41 templates covering NDAs, cloud service agreements, employment docs, contractor agreements, SAFEs, and NVCA financing documents.

Works with Claude Code, Gemini CLI, and Cursor.

Install

npm install -g open-agreements

Or run directly with zero install:

npx -y open-agreements@latest list

Quick Start

With Claude Code (zero install)

Just ask Claude:

> Fill the Common Paper mutual NDA for my company

Claude discovers templates, interviews you for field values, and renders a signed-ready DOCX. No install needed — Claude runs npx on demand.

With Gemini CLI

gemini extensions install https://github.com/open-agreements/open-agreements

Then ask Gemini to draft an agreement.

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, a few at a time)
• It runs fill <template> to render a DOCX preserving all original formatting
• You review and sign the output document

Local vs. Hosted Execution

OpenAgreements supports two execution modes:

• Local (npx, global install, or stdio MCP): all processing happens on your machine. No document content leaves your machine.
• Hosted (https://openagreements.org/api/mcp): template filling runs server-side for fast setup. No filled documents are stored after the response.

Choose based on document sensitivity and workflow needs. See docs/trust-checklist.md for a 60-second data-flow summary.

Privacy

• Local mode (npx, global install, stdio MCP): all processing happens on your machine. No document content is sent externally.
• Hosted mode (https://openagreements.org/api/mcp): template filling runs server-side. No filled documents are stored after the response is returned.

See our Privacy Policy for details.
