Q&A

Quick answers for teams evaluating Open Agreements.

What is Open Agreements? ▾
Open Agreements is an open-source CLI and library for filling standard legal agreement templates (DOCX) with structured inputs. It is designed to work directly with coding agents across hosted and local workflows.
Does Open Agreements send agreement data to remote servers? ▾
In local package mode, template fill runs on your machine and writes local files. If you use the hosted connector at https://openagreements.ai/api/mcp, request/response content passes through that hosted service.
What templates are supported today? ▾
The project includes internal templates (Common Paper, Bonterms, and employment packs), external vendored templates (YC SAFEs), and recipe-driven templates (NVCA Series A documents) downloaded from official sources at runtime. Browse the full catalog.
Can I use Open Agreements with Claude? ▾
Yes. Add https://openagreements.ai/api/mcp as a connector in Claude (Settings → Connectors → Add custom connector) and you can list templates, fill agreements, and download DOCX files directly from the chat.
How is template licensing handled? ▾
Licensing is enforced by template metadata and validation rules. Non-derivative sources are kept unchanged, and non-redistributable sources are handled through recipe instructions and runtime download.
Can Open Agreements generate .docx NDAs and Cloud Services Agreements? ▾
Yes. Open Agreements can generate editable .docx agreements from template inputs, including Non-Disclosure Agreements (NDAs) and Cloud Services Agreements (CSAs), with workflow options for hosted connector use or local package execution.
Can I use Open Agreements as an AI contract generator for startups? ▾
Yes. Open Agreements is built for agent-assisted contract drafting from structured prompts and form inputs. Startup teams can generate first-pass agreements in .docx, then review and negotiate them with counsel.
How can I verify Open Agreements is actively maintained and tested? ▾
Public trust signals include passing CI checks, Codecov coverage with patch/project gates, Vitest-based test runs, and scenario-to-test traceability checks that map canonical scenarios to executable tests.
Can I generate employment offer letters and IP assignment agreements? ▾
Yes. Open Agreements includes employment templates for offer letters, IP/inventions assignments, and confidentiality acknowledgements. The fill pipeline can also generate a jurisdiction-aware employment memo with compliance notes and disclaimers.
Does Open Agreements replace legal counsel? ▾
No. Open Agreements automates document assembly and workflow structure. Teams should still involve qualified legal counsel for legal advice, negotiation strategy, and jurisdiction-specific interpretation.
