PLAXIS · MCP

Drive PLAXIS 2D from any MCP client.

Geometry, staged construction, meshing, calculation and results — exposed as tools, over a hardened Windows-local stdio server.

Quickstart · Tools · Clients · Security model · Architecture

mcp-name: io.github.yixuanzhong/plaxis-mcp

▸ v0.3 — set up once, launch from anywhere

Client-neutral by design: Codex, Claude Code, Cursor, VS Code/Copilot and any other conforming local stdio MCP client connect to the same unprefixed server tools.

Quickstart

1 — Set up the machine, once.

plaxis-mcp.exe setup

Profiles land in %LOCALAPPDATA%\Caros\PLAXIS-MCP\profiles (override with --profile-dir). Add --skip-credentials to generate profiles now and store passwords later with plaxis-mcp.exe credentials set --profile .

The directory name is historical — it is where the first supported installer wrote —

and is kept because credential_target is derived from it.

2 — Run each role as its own process.

plaxis-mcp.exe serve --role input
plaxis-mcp.exe serve --role output

--config names a profile explicitly and is equivalent. Either way serve takes every endpoint setting from the profile and the password from Windows Credential Manager, and it fails to start if any PLAXIS_* endpoint environment override is present — so a client cannot silently redirect an endpoint or inject a password.

3 — Point a client at it. See Clients; the host never connects at startup, so call the connect tool once PLAXIS is running.

PLAXIS: common questions

Is PLAXIS MCP server safe?
Yes, by our scan: it is graded A (88/100). Read the PLAXIS safety report
How do I install PLAXIS?
It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
Does PLAXIS need an API key?
Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is PLAXIS maintained?
The last commit was 90 days ago (2026-08-06). The latest release is v0.3.5.
How does PLAXIS compare with other MCP servers?
safety score 88/100 (higher than 75% of 48,255 servers); tools 37 (the typical server has 7); tools that change things 24% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
