NeqSim MCP servers and AI agent skills

How AI connects to NeqSim

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

• Java library (Java): NeqSim is a Java library for fluid behaviour, phase equilibrium and process simulation, published to Maven Central. You define a fluid with an equation of state, add components, run flashes, then connect streams, separators, compressors and other equipment into a process system and run it. The MCP server is a Quarkus application built on this library, so every tool call is a Java calculation, not a lookup. Documentation
• Python package (neqsim) (Python): pip install neqsim gives Python access to the same Java engine, which suits notebooks and the task-solving agents. Many of the community skills ship small Python packages that call it, and fall back to placeholder logic if the package is missing, so confirm it is installed before you rely on a skill's numbers.

What Equinor (open source) offers

Equinor runs NeqSim as an agentic engineering project: the main repository contains the MCP server with three tool tiers and four deployment profiles, core skills and agents under .github, a neqsim CLI to install community and private skill catalogues, and a task solver that writes Word and HTML reports. These are first-party releases, not a separate product.

What you can do with NeqSim and AI

• Ask for a dew point, hydrate temperature or density at given conditions and get a NeqSim flash result with the equation of state and convergence status attached.
• Draw a phase envelope for a natural gas composition, or a property table across a pressure range.
• Simulate a short process such as separation and compression to export pressure from a JSON definition, and read back stream conditions and compressor power.
• Screen TEG dehydration, hydrate margin, produced-water scale or vacuum collapse with the community skills, then hand the result to an engineer for review.
• Run the server in an advisory-only profile for operators, so tools that change sessions or write variables are blocked.

Installing

The listings here document setup for Claude, 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 NeqSim integrations run on your own computer next to NeqSim, so you need NeqSim installed and licensed on the same machine unless the listing says otherwise.
