MCP 服务器

loadbench-mcp

An MCP server that provides structural load and stability math (tipping, support reactions, beam checks) that language models often get wrong, enabling AI assistants to compute accurate engineering estimates.

README

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.
