MCP server for structural load & stability math: tipping, support reactions, beam checks.

VerifiedSTDIODesktop onlyDeveloper Tools

Overview

AI-generated overview

Local MCP server that runs structural load and stability calculations — tipping, support reactions, and beam stress and deflection — for an AI assistant.

What you can do
  • Check whether a set of weights will tip over their footprint
  • Work out how much load each leg or bracket carries
  • Check whether a beam or shelf holds a given load, including stress and deflection
  • Return SI-unit results (metres, kilograms, newtons) from arguments described in the tool docstrings
When to use it
Useful when an assistant is asked planning-style questions about shelves, brackets, stands or other simple structures and would otherwise guess the physics. Good for quick sanity checks on tipping, support loads and beam capacity.
Requirements
Runs as a local process over stdio, launched with uvx or installed via pip; needs Python and the numpy dependency. No accounts, API keys or environment variables are declared. Inputs are expected in SI units.
Before you install
Results are planning estimates, not certified engineering; the README says loads where failure could cause injury or damage should be checked by a qualified engineer. It only computes numbers and does not modify data.

Installation

In SourceWeft

  1. Open Loadbench in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

loadbench-mcp

An MCP server that does the structural load & stability math language models get wrong. AI assistants call it instead of guessing.

ToolQuestion it answers
check_tippingWill these weights topple over their footprint?
solve_supportsHow much load does each leg / bracket carry?
beam_checkWill 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-mcploadbench-mcp

Use it in Claude Desktop

Add to your claude_desktop_config.json:

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 sourcepython -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.

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
