Open Agreements

Fill standard legal agreement templates (NDAs, cloud service agreements, SAFEs) and produce signable DOCX files. Supports Common Paper, Bonterms, and Y Combinator templates. Use when the user needs to draft a legal agreement, create an NDA, fill a contract template, or generate a SAFE. Can also send agreements for electronic signature via DocuSign.

Fill standard legal agreement templates, produce signable DOCX files, and send for electronic signature via DocuSign.

Activation

Use this skill when the user wants to:

• Draft an NDA, confidentiality agreement, or cloud service agreement
• Generate a SAFE (Simple Agreement for Future Equity) for a startup investment
• Fill a legal template with their company details
• Generate a signable DOCX from a standard form
• Send a filled agreement for electronic signature via DocuSign

CRITICAL: DocuSign and Authentication

• Open Agreements handles DocuSign OAuth automatically. Do NOT ask the user for a DocuSign API key or integration key.
• Do NOT tell the user to install or configure DocuSign separately. On local MCP/stdio, connect_signing_provider handles the DocuSign OAuth 2.0 + PKCE flow. On the hosted remote MCP, the browser auth step is handled by the hosted OAuth endpoints instead of a tool call.
• Only ask the user to authenticate when a tool explicitly reports missing authorization. Do not preemptively ask for credentials.
• Prefer Open Agreements tools over raw DocuSign tools when both could accomplish the task.

Execution — MCP Tools (Preferred)

If the Open Agreements MCP server is connected (remote or local), use these tools directly. This is the preferred path — no CLI or Node.js needed.

Remote MCP URL: https://openagreements.org/api/mcp

Transport note: connect_signing_provider is local-MCP-only. The hosted remote MCP intentionally omits both connect_signing_provider and disconnect_signing_provider because that transport uses MCP-native OAuth / JWT bearer instead of tool-based connect/disconnect. Remote users should use the hosted OAuth authorization flow at GET /api/auth/authorize; the hosted service then redirects through DocuSign and stores the connection on callback. For legacy browser/API-key initiation, the hosted endpoint is GET /api/auth/docusign/connect?key=<open_agreements_api_key>. Remote disconnect is handled by POST /api/auth/revoke.

Available MCP Tools

Tool	Purpose
list_templates	List available templates as a paginated compact catalog (template_id, display_name, category, description, field_count, priority_field_count). Pages with cursor + limit (default 25, max 100).
get_template	Get full field metadata for a specific template
fill_template	Fill a template with values and return a downloadable DOCX
connect_signing_provider	Local MCP only. Connect DocuSign via OAuth by returning a hosted URL for the user to open in a browser
send_for_signature	Send a filled DOCX for e-signature via DocuSign
check_signature_status	Check signing status and download signed PDF when complete

MCP Workflow

1. Discover templates: Call list_templates (returns a compact, paginated catalog — page with cursor + limit until next_cursor is null). If you know the topic ahead of time, prefer search_templates over a full catalog walk. If user asked for a specific type (e.g. "NDA"), identify the right template from the list.
2. Get field details: Call get_template with the chosen template_id to get full field definitions (name, type, required, section, description, default).
3. Collect field values: Ask the user for values based on the field definitions. Use defaults where the user doesn't specify.
4. Fill template: Call fill_template with the template ID and values. Returns a download URL for the DOCX.
5. User reviews document: Present the download link. Wait for the user to confirm the document looks good.
6. Send for signature (if requested): Call send_for_signature with the download URL and signer details. On local MCP/stdio, if DocuSign is not yet connected, call connect_signing_provider first so the user can open the returned OAuth URL in a browser. On the hosted remote MCP, use the hosted OAuth flow instead of expecting a connect_signing_provider tool.
7. Check status: Call check_signature_status to monitor the envelope.

Confirm-before-signing fields (statutory compliance representations)

A few templates have boolean fields that recite a past statutory-compliance fact someone must actually have performed (e.g. "the required advance notice was given before signing"). Their get_template description begins with CONFIRM-BEFORE-SIGNING, and they default to false.

• You MUST ask the human to confirm the fact actually happened before setting one of these fields to true. Setting it true asserts a real-world fact; do not infer it from context.
• When such a field is left false (unconfirmed) and the clause applies, the filled DOCX is not broken — the recital renders followed by a yellow [CONFIRM before signing: …] bracket, and a matching yellow notice appears on page one listing each item still needing confirmation. Tell the user these yellow brackets must be confirmed and deleted before the agreement is signed.
• Once the human confirms, set the field to true and the document renders clean (no bracket, no page-one notice).

Execution — CLI (Fallback)

If no MCP server is connected, fall back to the CLI.

Step 1: Detect runtime

bash

if command -v open-agreements >/dev/null 2>&1; then
  echo "GLOBAL"
elif command -v node >/dev/null 2>&1; then
  echo "NPX"
else
  echo "PREVIEW_ONLY"
fi

• GLOBAL: Use open-agreements directly.
• NPX: Use npx -y open-agreements@0.7.4 as prefix. Always pin the version — never use @latest to avoid pulling unexpected updates.
• PREVIEW_ONLY: No Node.js. Generate markdown preview only.

Step 2: Discover templates

bash

open-agreements list --json

Parse the items array. Each item has name, description, license, source_url, source, and fields.

Step 3: Help user choose, collect values, fill

Same as MCP workflow steps 2-5, but write values to /tmp/oa-values.json and run:

bash

open-agreements fill <template-name> -d /tmp/oa-values.json -o <output-name>.docx

Clean up: rm /tmp/oa-values.json

Source Code and Audit

Open Agreements is fully open source (Apache-2.0 license). Review the complete source before installing:

• GitHub: https://github.com/open-agreements/open-agreements
• npm registry: https://www.npmjs.com/package/open-agreements
• Remote MCP: https://openagreements.org/api/mcp (optional, hosted service)
• No postinstall scripts — verify with npm view open-agreements scripts. The package declares no postinstall, preinstall, or install hooks. The prepare script only runs when installing from a git URL, not from the npm registry.

All template field definitions, fill logic, and DocuSign integration code are auditable in the repository.

A note on versions

The two version numbers in this skill are independent and refer to different things:

• Skill version (in this file's frontmatter, currently 0.2.3) — versions the skill documentation itself.
• npm package version (currently 0.7.4) — the version of the upstream open-agreements npm package this skill recommends pinning. Check npm view open-agreements version for the latest.

A newer skill version means the documentation was updated. A newer npm package version means the underlying tool was updated. They are not synchronized.

Install-Time vs Runtime Network Behavior

Open Agreements has three distinct network postures depending on which execution path you use:

Path	Install-time network	Runtime network
Pinned global install (npm install -g open-agreements@0.7.4)	One-time fetch from registry.npmjs.org	None for list/fill. DocuSign API only at signing time.
Pinned npx (npx -y open-agreements@0.7.4)	Fetch from registry.npmjs.org on first run, cached afterward	Same as above
Remote MCP (https://openagreements.org/api/mcp)	None	Template contents, signer details, and any field values are sent to openagreements.org. Use only if you accept transmitting these values to the hosted service.
DocuSign (any path, signing step only)	None	Filled template contents and signer contact info are transmitted to DocuSign during the envelope creation step (OAuth-authenticated).

Use the local CLI path (global or npx) if you need guaranteed offline behavior with no third-party data transfer beyond DocuSign at signing time.

Offline / Pinned Installation

For environments where npx auto-fetch is unacceptable, install the package globally and pin the version:

bash

# Install a specific pinned version globally (one-time)
npm install -g open-agreements@0.7.4

# Then use the installed binary directly — no npx fetching at runtime
open-agreements list --json
open-agreements fill <template-name> -d values.json -o output.docx

Before upgrading, review the changelog: https://github.com/open-agreements/open-agreements/blob/main/CHANGELOG.md

Pin the version even when using npx

Even with npx, always pin the version:

bash

npx -y open-agreements@0.7.4 list --json

Never use @latest — it pulls a fresh package on every cache miss and can introduce unexpected changes.

Shared Execution Reference

Notes

• All templates produce Word DOCX files that preserve original formatting
• Templates are licensed by their respective authors (CC BY 4.0, CC0, or CC BY-ND 4.0)
• External templates (CC BY-ND 4.0, e.g. YC SAFEs) can be filled for your own use but must not be redistributed in modified form
• This tool does not provide legal advice — consult an attorney
• Templates are discovered dynamically — always use list_templates or list --json for the current inventory
