PLECS MCP servers and AI agent skills
Two community MCP servers drive PLECS Standalone through its built-in XML-RPC/JSON-RPC server, which must be switched on in Preferences and only accepts connections from the same computer. PLECS-MCP wraps all 22 RPC methods of PLECS 5.0 and adds model checks, plots and FFT/THD analysis; a smaller server maps 11 calls for PLECS 4.7. Neither covers PLECS Blockset in Simulink, and Plexim has announced no AI features.
- No official Plexim server yet.
- 2 MCP servers listed.

How AI connects to PLECS
An MCP server or skill can only do what PLECS lets programs do. PLECS exposes 2 automation interfaces:
- RPC interface (XML-RPC and JSON-RPC) (Other): PLECS Standalone can act as an HTTP server for XML-RPC or JSON-RPC requests, off by default and enabled in the preferences with a TCP port (1080 by default). Clients must run on the same computer. Simulations and analyses block, and only one runs at a time, so MCP servers queue them or use the parallel-execution option. Python's standard xmlrpc client is enough to connect, as Plexim's own controller-design tutorial shows. Documentation
- Simulation scripts and Blockset command line (Other): Inside PLECS Standalone, simulation scripts run in GNU Octave to set parameters, run simulations and analyses in parallel, and control scopes. PLECS Blockset is scripted from MATLAB instead, with Simulink handling simulation control and a plecs() command for parameters and scope data. The RPC interface, and so the MCP servers, apply to Standalone only. Documentation
What Plexim offers
Plexim's PLECS documentation and site describe scripting through Octave, MATLAB and the RPC interface, and no Plexim announcement of an AI assistant, LLM feature or MCP server turned up as of this check. The PLECS MCP servers are community projects built on the documented RPC interface.

What you can do with PLECS and AI
- Load a .plecs model, set parameters such as input voltage or load resistance, run a simulation and report min, max, mean and RMS per output.
- Run an AC sweep or loop-gain analysis and report gain crossover and phase margin.
- Check a model's connections and layout before simulating, and return scope captures or Bode plots as images.
- Compute FFT and THD from saved results, or run pass/fail checks on signals for a converter design.
- Trigger code generation or export an atomic subsystem as an FMU.

Installing
The listings here document setup for Claude Code, Claude Desktop, Codex, Cursor and VS Code (GitHub Copilot). Install steps, copied from each project's own documentation, are on each listing's page. Most PLECS integrations run on your own computer next to PLECS, so you need PLECS installed and licensed on the same machine unless the listing says otherwise.

Questions
Is there an official PLECS MCP server?
No. Plexim documents the RPC interface the community servers use, but it hasn't announced an AI or MCP product.
Can Claude run PLECS simulations?
Yes, with PLECS Standalone open on the same computer, RPC enabled in Preferences, and one of the two servers installed there. PLECS-MCP can also start PLECS for you when the RPC port is closed.
Does this work with PLECS Blockset in Simulink?
No. Plexim's documentation says Blockset is scripted from MATLAB and has no built-in RPC interface, so both servers need PLECS Standalone.
Which PLECS versions do the servers support?
PLECS-MCP was checked against PLECS 5.0.7, where it covers all 22 RPC methods. The haitangccy server was written for PLECS 4.7 Standalone over XML-RPC on port 1080. Both expect a valid PLECS licence on the machine.
AI-generated models, drawings and results must be checked by a qualified engineer before use.
