SalomeMCP

SALOME Model Context Protocol for agentic use

Overview

This repository provides three components:

1. SALOME GUI plugin to start/stop the local bridge port.

2. SALOME-side bridge (salome_bridge.py) that executes GEOM/SMESH operations.

3. MCP server (salome-mcp) that agent clients connect to.

Related MCP server: COMSOL MCP Server

Requirements

1. SALOME 9.x

2. Python 3.10+

3. uv

Setup

1) Install Python dependencies

cd /path/to/salome-mcp
uv sync

2) Install SALOME plugin files

mkdir -p ~/.config/salome/Plugins   # or wherever your plugins folder is located
cp salome_plugin/*.py salome_bridge.py ~/.config/salome/Plugins/

Configure MCP Client

It is recommended that you set up the MCP server inside a particular project instead of globally.

Claude Code CLI (from inside your project root)

claude mcp add --scope project salome -- uv run --directory /path/to/salome-mcp salome-mcp

Codex CLI (from inside your project root)

mkdir -p .codex && cat > .codex/config.toml <<'EOF'
[mcp_servers.salome]
command = "uv"
args = ["run", "--directory", "/path/to/salome-mcp", "salome-mcp"]
EOF

Custom Host and Port

By default, the bridge uses localhost:1234. You can set your custom host/port in the SALOME GUI bridge settings, then simply prompt your agent to connect to that.

Usage

1. Start SALOME and start: Tools -> PLugins -> MCP Bridge -> Start (default)

2. Open your agent and prompt it to "ping salome". The agent should be able to use check_salome_status and return success

3. The agent should now be able to make tool calls based on your prompts. Check samples

4. End session with MCP Bridge -> Stop

Tool Coverage

These are the tool calls that can be used by your agent. You probably don't need to know this

General

• ping_salome, check_salome_status, get_study_info, get_scene_summary, list_study_objects: Session and study status/overview

Geometry (GEOM)

• create_box, create_cylinder, create_sphere, create_naca4_airfoil: Primitive creation

• translate_object, rotate_object, copy_object, duplicate_object, rename_object, delete_object: Transforms and object lifecycle

• boolean_operation, fuse_objects, cut_objects, common_objects: Boolean operations (fuse, cut, common)

• create_group, create_groups, create_surface_group, create_volume_group: Group creation

• make_partition, explode_shape, import_geometry, export_geometry, get_object_info, list_subshapes: Partition, explode, I/O, and inspection

Mesh (SMESH)

• import_mesh, export_mesh: Mesh I/O

• create_mesh: Standard mesh setup with hypotheses

• create_mesh_with_hypotheses: Explicit algorithm + detailed hypotheses meshing

• compute_mesh, get_mesh_info: Mesh compute and statistics

Advanced

• execute_salome_code (raw Python code)

Samples

Prompt 1

lets do these step by step: 1. make a cylinder r = 4 h =8 and place it along x axis 2. make two more cylinders of r = 2 and h = 4 3. place these cylinders on either of the circular ends 4. carve a cylinder out of these smaller ones to make two shells of rout = 2 and rin = 1 5. fuse all 6. create the single vol group 7. make surface groups inlet outlet and walls 8. make a mesh with netgen 1d 2d 3d very fine mesh. 9. compute mesh and report its stats

Prompt 2

1.make a naca 4412 airfoil 2. create a fluid box region around it for wind tunnel testing 3. cut the region for the air 4. make a partition and name all surface and vol groups 5. generate a netgen 1d2d3d coarse mesh 6. report mesh stats
