• Show HN: SolidCraft – Open-Source Parametric CAD in Rust (With MCP Support) · score 8.0

  SolidCraft is a pure-Rust parametric 3D CAD application with a constraint solver, feature timeline, assemblies, sheet metal, and file format support, available as desktop, web, CLI, and MCP server. It stands out for its unified command-based architecture and AI-agent integration, offering a credible open-source alternative to established CAD tools.

• Show HN: Hackerscad – Code-first CAD with MCP server for AI agents · score 7.8

  Hackerscad is a code-first parametric CAD tool where models are written in a small D-like scripting language, with mouse interaction that writes code back, and an MCP server enabling AI agents to create and manipulate 3D models. It combines OpenCascade B-rep solids, a custom language with sandboxing, bidirectional code/GUI editing, and AI-agent integration into a single desktop application. The project is technically ambitious and fills a gap for AI-assisted parametric CAD.

• Show HN: WhatsApp MCP running free on Cloudflare · score 7.8

  A serverless MCP server running on Cloudflare Workers that lets AI agents read and search your personal WhatsApp messages by linking as a device. It uses Durable Objects and SQLite for storage, runs Baileys in workerd, and handles OAuth and QR pairing. The project is notable for its clever adaptation of WhatsApp Web protocol to a serverless edge environment and its pragmatic agent-driven contact naming.

• Show HN: OpenComputerUse – Background computer use for agents, as an MCP server · score 7.8

  OpenComputerUse is an MCP server that enables AI agents to control GUI applications in the background without disturbing the user's pointer, keyboard focus, or frontmost app. It provides a rich set of tools for session management, screenshots, UI tree access, and element interactions, with cross-platform support and innovative features like recipes and extraction via Cloudflare models.
