Itasca FLAC, 3DEC and PFC MCP servers and AI agent skills

How AI connects to Itasca FLAC, 3DEC and PFC

An MCP server or skill can only do what Itasca FLAC, 3DEC and PFC lets programs do. Itasca FLAC, 3DEC and PFC exposes 2 automation interfaces:

• Embedded Python (itasca module) (Python): Each ITASCA engine embeds Python with an itasca module (imported as it) that reads and changes zones, gridpoints and structural elements and sends ordinary commands through it.command(). Start scripts with python-reset-state false, or Python variables vanish on model new or model restore. The MCP bridges run inside this embedded interpreter, which is why they must be started from the engine's own console. Documentation
• FISH and data files (Other): FISH is ITASCA's built-in scripting language, and data files of commands and FISH functions can be executed from the engine's editor. The documentation tools in itasca-mcp and 3dec-mcp index commands, FISH intrinsics and the Python API per engine and version, so an agent can check syntax before running anything. Documentation

What Itasca offers

ITASCA offers GeoBOT, an AI assistant trained on its software documentation for technical support questions; it answers questions but does not control the software. ITASCA has not released an MCP server, so the servers that run FLAC, 3DEC or PFC from an agent are community projects.

What you can do with Itasca FLAC, 3DEC and PFC and AI

• Run a biaxial compression test on a dense PFC specimen and plot the stress-strain curve.
• Build a FLAC3D slope model and find its factor of safety, checking command syntax against the documentation first.
• Check the unbalanced force of a long FLAC or 3DEC run while it is still cycling, without interrupting it.
• Model a tunnel in jointed rock in 3DEC and report block displacements around the opening.
• Calibrate PFC 5.0 asphalt-mixture specimens and run Marshall or wheel-tracking tests with FISH.

Installing

The listings here document setup for Claude Code, Codex, Codex CLI, Gemini CLI, GitHub Copilot CLI, OpenCode and VS Code (Codex). Install steps, copied from each project's own documentation, are on each listing's page. Most Itasca FLAC, 3DEC and PFC integrations run on your own computer next to Itasca FLAC, 3DEC and PFC, so you need Itasca FLAC, 3DEC and PFC installed and licensed on the same machine unless the listing says otherwise.
