TOOL
autocad-plant3d-mcp lets Claude Code, Claude Desktop or another MCP client build, check and renumber P&IDs in AutoCAD Plant 3D through its .NET API, so lines carry real connections and pass validation. It also runs read-only checks on the project database for duplicate tags, orphan objects and open line ends. A chemical engineering student built it from a two-semester plant design project.
For process design engineers and EPC tool builders: on AutoCAD Plant 3D.

smt-floor-mcp simulates a three-line SMT electronics floor with injected anomalies and keeps the answer key separate, so you can score whether an agent finds the real cause of a slowdown. The simulator and a read-only OPC UA server are done; the MCP server itself is still in progress.
For electronics manufacturing engineers: testing agents on line data.
TOOL
multi-plc-agent runs one MCP server that lets an AI agent write ladder logic in nine PLC tools, including GX Works2, TIA Portal V20, CX-Programmer, Sysmac Studio and CODESYS. A tool is checked off only after a real program built with 0 errors and read back matched. Tools that act on a live PLC or delete project content are not exposed, so the agent writes and compiles offline.
For controls and automation engineers: testing AI-written ladder logic offline.

TOOL
ethercat-mcp is an MCP server that lets an AI assistant scan EtherCAT slaves, step the state machine, read and write CoE objects and PDO data, and diagnose bus health. It ships with a five-slave virtual bus of Beckhoff and Inovance devices, so it can be tested without hardware. It also exposes CiA 402 servo commands like enable, jog and positioning, so keep it on the simulator and away from a live line.
For controls engineers: who want to test agent tooling against a simulated EtherCAT bus.
