What can you do with this server?

This server allows you to discover, retrieve, and fill legal agreement templates (40+ across NDAs, cloud service agreements, employment docs, SAFEs, NVCA financing documents, etc.) to produce signable DOCX files. * List templates (list_templates): Browse all available templates in compact or full metadata mode (includes fields, licenses, sources). * Get template details (get_template): Fetch a single template's full definition and field metadata by ID (e.g., common-paper-mutual-nda), so you know exactly what values are needed. * Fill a template (fill_template): Render a filled, signable DOCX by providing a template ID and required field values. Output can be returned as a local file path or inline base64-encoded string.

Which integrations are available for this server?

Provides automated filling and generation of standard Y Combinator (YC) SAFEs as part of its external template library.

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.

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

Gemini CLI

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.
