The record

Purpose: OpenTakeoff is a construction takeoff engine for measuring quantities from building plans, with a browser canvas for people and an MCP server for AI agents.
Plan files: The browser app opens PDF plan sets, images and ZIP plan sets, processing them locally without an account or plan upload.
Measurement outputs: It reports quantities including square feet, square yards, linear feet and each, with waste-adjusted order quantities, supporting-materials lists and roll-goods cuts.
Exports: The app exports CSV, Excel and marked PDF files.
Agent integration: The MCP server runs through `npx -y opentakeoff-mcp` and supports Claude Code, Claude Desktop, Cursor and other stdio MCP clients.
Agent review: Agent measurements remain pending proposals until a person approves them in the browser canvas.
Default feature limit: One-Click Area is temporarily gated while its flood engine is re-validated; the default MCP build does not register its room-detection verbs.
Local privacy: In the default browser workspace, plans, measurements, annotations, materials and project settings are processed on the device and stored in browser storage.
Optional integrations: Optional connections include Google Drive and Microsoft 365 cloud storage, configured AI providers, and a scanned-schedule service that can send a selected image to Google Gemini.
Security and compliance: The privacy policy says no storage or transmission method is risk-free; it does not state a security certification or compliance standard.
Platforms: The browser canvas runs on Windows, macOS, ChromeOS and Linux in current Chrome, Edge, Firefox or Safari; the MCP server runs on Windows, macOS and Linux.
Self-hosting: The project is Apache-2.0 licensed and says users can fork it to run their own instance on their own URL.
Support: Users can contact Michael Edlin by email or open a support issue; the policy notes that GitHub issues are public.
Intended users: The privacy policy says the service is intended for construction professionals and developers, not children under 13.
