Or run directly with zero install:

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

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

Available Templates

The Source column links to the upstream standard, source document, or canonical project page (varies by publisher). The License column shows redistribution terms. Repo links point to the GitHub content directory for each template or recipe.

• 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.
