Code_Aster MCP servers and AI agent skills

How AI connects to Code_Aster

An MCP server or skill can only do what Code_Aster lets programs do. Code_Aster exposes 3 automation interfaces:

• Python command files (.comm) (Python): A code_aster study is a command file in Python: a sequence of commands, each documented in the user manual under its own number (DEFI_MATERIAU, for example, is U4.43.01). Because the file is plain Python, an agent can write or edit it like any script, then hand it to the solver. The test-case base on the project site is the usual starting point for a new study. Documentation
• run_aster and the code_aster Python package (Command line): Recent versions are run through the run_aster script, and the developer documentation describes the code_aster and run_aster Python packages, including helpers for temporary folders and copying data and result files. A future MCP server that runs solves would most likely wrap run_aster. Documentation
• MED result files (Input files): code_aster writes results in the MED format. Aster View reads these files directly with the h5py library, so results can be inspected on machines without code_aster or salome_meca, and exported to VTU for ParaView builds that lack a MED reader.

What EDF (open source) offers

code_aster is EDF's open-source finite element solver for mechanics, thermal analysis and dynamics, used alongside the salome_meca platform and developed in the open on GitLab. The project site announces user meetings and releases but no AI assistant or MCP server as of this check, so the only integration listed here is a community viewer.

What you can do with Code_Aster and AI

• List the meshes, groups, fields and time steps in a .rmed file and flag a truncated result.
• Report the maximum von Mises stress over a named group, with its location and percentiles, using Gauss-point values.
• Extract a time history at a node or a stress profile along a line, with a journal-ready plot.
• Render a cut plane or threshold view to PNG and convert results to VTU for ParaView.
• Build a journal-quality figure of a field on the deformed shape from a saved recipe, so the same view can be regenerated after each new run.

Installing

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