Aspen Plus MCP servers and AI agent skills

How AI connects to Aspen Plus

An MCP server or skill can only do what Aspen Plus lets programs do. Aspen Plus exposes 2 automation interfaces:

• COM automation (Aspen Plus as an ActiveX automation server) (COM automation): The Aspen Plus user interface registers itself as a COM automation server, so any Windows language with COM support (Python with pywin32, VBA, MATLAB, C#) can open a simulation and walk its variable tree. Inputs and results sit at backslash paths such as \Data\Streams\FEED\Input\TEMP, which you find with the Variable Explorer. Every MCP server below is built on this route. AspenTech's reference for it is in the product help and the AspenTech Support Center, which needs a customer login; the public product page doesn't document it. Documentation
• Input files (.inp) and backup files (.bkp) (Input files): A case can also be described as a keyword input file and loaded into Aspen Plus, which is how the aspen-assistant skill turns a JSON flowsheet into a runnable model. The servers below mostly open and save .bkp or .apw files, and some export the .rep report as well. Documentation

What AspenTech (Emerson) offers

AspenTech, now an Emerson company, offers the Aspen Virtual Advisor (AVA) generative AI assistant; the V15 release expanded it to help users understand model results inside the product. In May 2026 Emerson described AVA as an industrial AI platform with agentic advisors for operations software. Neither announcement mentions MCP or outside agents driving Aspen Plus, so every server listed here is a community project.

What you can do with Aspen Plus and AI

• Open an existing .bkp or .apw case, change a feed temperature or a RadFrac reflux ratio, rerun and report the product stream table and block duties.
• Build a flowsheet from a brief or a JSON spec, including components, a property method such as NRTL or PENG-ROB, blocks, streams and port connections.
• Find out why a run failed by scanning for missing inputs, reading block status and searching a convergence knowledge base, then set tear-stream estimates and retry.
• Run a sensitivity sweep or a multi-objective optimisation (NSGA-II in one server) over block inputs and collect the results in a table.
• Size column internals with RadFrac Column Internals, or estimate capital and operating cost, through the servers that add those tools.

Installing

The listings here document setup for Claude Code, Claude Desktop, Codex, Cursor, DeepSeek Harness, Gemini CLI, OpenClaw, Reasonix and VS Code. Install steps, copied from each project's own documentation, are on each listing's page. Most Aspen Plus integrations run on your own computer next to Aspen Plus, so you need Aspen Plus installed and licensed on the same machine unless the listing says otherwise.
