Documentation Overview

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:

Code

uvx loadbench-mcp

Or install it:

Terminal

pip install loadbench-mcp
loadbench-mcp

Use it in Claude Desktop

Add to your claude_desktop_config.json:

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

Code

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.
