Loadbench
MCP server for structural load & stability math: tipping, support reactions, beam checks.
Runs on your machine from its package; the steps are below.
What it does
- Reads
- Writes
- High impact
At most: only reads or looks up information.
What it costs
FreeOdel charges nothing per call. The publisher may charge for its own service.
Runs locally over stdio
This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).
Run
uvx loadbench-mcp
MCP client config
{
"mcpServers": {
"loadbench": {
"command": "uvx",
"args": [
"loadbench-mcp"
]
}
}
}loadbench-mcp
An MCP server that does the structural load & stability math language models get wrong. AI assistants call it instead of guessing.
| Tool | Question it answers |
|---|---|
check_tipping | Will these weights topple over their footprint? |
solve_supports | How much load does each leg / bracket carry? |
beam_check | Will this beam or shelf hold the load? (stress + deflection) |
All math is verified against hand-computed answers (tests/test_physics.py).
Install & run
Once published to PyPI, any MCP client can launch it with no install step:
uvx loadbench-mcp
Or install it:
pip install loadbench-mcp
loadbench-mcp
Use it in Claude Desktop
Add to your claude_desktop_config.json:
{
"mcpServers": {
"loadbench": {
"command": "uvx",
"args": ["loadbench-mcp"]
}
}
}
Restart Claude Desktop, then ask things like "A 2 m pine shelf on two brackets 0.3 m from each end — will it hold 40 kg in the middle?"
Local development
uv run --with mcp --with numpy python -m load_solver.server # run from source
python -m pytest tests # verify the math
Inputs are SI units (metres, kilograms, newtons; 1 kg ≈ 9.81 N). Tool docstrings carry the full argument details, which the model reads automatically.
Estimates for planning, not certified engineering. For loads where a failure could cause injury or real damage, have a qualified engineer check the result.
