Openroad Mcp
Brings OpenROAD, the open source RTL-to-GDS digital design tool, into your AI coding environment through persistent PTY sessions. You can run OpenROAD commands interactively, manage multiple sessions, pull command history, and access performance metrics without leaving your editor. It also integrates with OpenROAD Flow Scripts to visualize report images from full chip builds. Requires OpenROAD in your PATH and Python 3.13+. The server works over stdio with uvx, so setup is a one-liner in most MCP clients. Reach for this if you're doing chip design work and want to iterate on floorplans, timing analysis, or placement runs conversationally instead of jumping between terminals and GUIs.

OpenROAD MCP Server
A Model Context Protocol (MCP) server that provides tools for interacting with OpenROAD and ORFS.
About OpenROAD MCP
New here? Check out the Quick Start Guide to get your AI assistant analyzing designs in 5 minutes.
OpenROAD MCP eliminates the barrier between your AI assistant and physical design by connecting Claude, Cursor, and other MCP-compatible clients directly to the OpenROAD layout tools.
OpenROAD is the leading open-source, foundational application for semiconductor digital design, delivering an Autonomous, No-Human-In-Loop (NHIL) flow from RTL-GDSII. OpenROAD-flow-scripts (ORFS) is the fully autonomous flow built around it.
