Open Agreements

open-agreements

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

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.

Execution — CLI (Fallback)

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

Step 1: Detect runtime

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

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:

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 (MIT 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:

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:

# 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:

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.

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
