open-agreements
Fill standard legal agreement templates and produce filled DOCX files.
Route to the narrowest skill
Use open-agreements as the hub when a request spans agreement types, starts
with template discovery, or does not yet identify a specific agreement. When
the request is precise, route to the narrowest spoke:
| User’s task | Route to |
|---|---|
| NDA, confidentiality agreement, mutual or one-way NDA | nda |
| SaaS agreement, MSA, cloud contract, order form, pilot agreement | cloud-service-agreement |
| Consulting contract, contractor agreement, services agreement, SOW | services-agreement |
| Offer letter, employment agreement, PIIA, employee onboarding documents | employment-contract |
| DPA, GDPR addendum, HIPAA BAA, data-processing or AI addendum | data-privacy-agreement |
| YC SAFE, valuation cap, discount, MFN, or pro-rata side letter | safe |
| NVCA or Series A financing documents | venture-financing |
| Explain non-compete or restrictive-covenant law | non-compete-contract-explainer |
| Explain U.S. state consumer-privacy law | data-privacy-law-explainer |
The spoke names are routing targets, not separate brands. They install from the
same open-agreements/open-agreements bundle. Keep this hub as the fallback for
mixed or ambiguous agreement work.

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 filled DOCX from a standard form
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
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 |
MCP Workflow
- Discover templates: Call
list_templates(returns a compact, paginated catalog — page withcursor+limituntilnext_cursorisnull). If you know the topic ahead of time, prefersearch_templatesover a full catalog walk. If user asked for a specific type (e.g. “NDA”), identify the right template from the list. - Get field details: Call
get_templatewith the chosentemplate_idto get full field definitions (name, type, required, section, description, default). - Collect field values: Ask the user for values based on the field definitions. Use defaults where the user doesn’t specify.
- Fill template: Call
fill_templatewith the template ID and values. Returns a download URL for the DOCX. - User reviews document: Present the download link. Wait for the user to confirm the document looks good.
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
trueand 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
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-agreementsdirectly. - NPX: Use
npx -y open-agreements@0.7.4as prefix. Always pin the version — never use@latestto 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 (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 nopostinstall,preinstall, orinstallhooks. Thepreparescript only runs when installing from a git URL, not from the npm registry.
All template field definitions and fill logic 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 upstreamopen-agreementsnpm package this skill recommends pinning. Checknpm view open-agreements versionfor 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. |
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 and any field values are sent to openagreements.org. Use only if you accept transmitting these values to the hosted service. |
Use the local CLI path (global or npx) if you need guaranteed offline behavior with no third-party data transfer.
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_templatesorlist --jsonfor the current inventory
