# FERS Cloud

> FERS Cloud is browser-based finite-element structural analysis: 3D beams,
> frames and trusses, linear & nonlinear, Eurocode EN 1993-1-1 (EC3) steel
> checks with a transparent hand-calc trace. AI agents connect via the remote
> MCP server at https://ferscloud.com/api/mcp (streamable HTTP; OAuth 2.1 or
> X-API-Key header; 100 free solves/week, then €0.01/solve). Results are
> validated against closed-form solutions.

## AI & API

- [MCP server for AI agents](https://ferscloud.com/mcp): connect Claude, ChatGPT, Cursor or VS Code; 37 tools incl. solve_model, check_beam, build_model, set_analysis (modal/buckling/seismic), add_load, add_plate_surface and get_schema; only the 3 solve tools are metered. Also in [Spanish](https://ferscloud.com/es/mcp), [German](https://ferscloud.com/de/mcp), [Dutch](https://ferscloud.com/nl/mcp), [French](https://ferscloud.com/fr/mcp) and [Romanian](https://ferscloud.com/ro/mcp)
- [OpenAPI spec](https://ferscloud.com/api/openapi.json): REST twin of the MCP tools, for ChatGPT Custom GPT Actions and OpenAPI toolkits
- [Ask FERS demo](https://ferscloud.com/ask): plain-English beam check in the browser, no install

## Docs

Every page below also has a plain-Markdown twin at the same URL with `.md`
appended (e.g. https://ferscloud.com/docs/javascript.md), and the whole set is
available in a single fetch at https://ferscloud.com/llms-full.txt

- [Getting started](https://ferscloud.com/getting-started): hub — what FERS is, and which route (browser, Python, JavaScript, REST, agent) fits
- [Quickstart](https://ferscloud.com/docs/quickstart): build and solve a 3D frame in the browser, no install
- [Install the Python package](https://ferscloud.com/docs/installation): pip install FERS, verify, optional API-key auth
- [Python API](https://ferscloud.com/docs/python-api): core objects, geometry, solve, read results
- [Python examples](https://ferscloud.com/docs/python-examples): cantilever, simply supported beam, portal frame, EN 1993-1-1 check — each with its closed-form hand check
- [JavaScript / WebAssembly](https://ferscloud.com/docs/javascript): npm install @ferscloud/fers-calculation-web, bundler setup for Vite and Next.js, the result envelope, TypeScript types, Pro solve tokens
- [REST API reference](https://ferscloud.com/docs/rest-api): every SDK endpoint with request and response payloads
- [Keyboard shortcuts](https://ferscloud.com/docs/keyboard-shortcuts): the modelling workspace
- [Modeling conventions & units](https://ferscloud.com/conventions): axes, sign conventions, SI units

## Libraries

- [Structural analysis in Python](https://ferscloud.com/structural-analysis-python): `pip install FERS` — build models as objects, solve locally, no account needed
- [Structural analysis in JavaScript](https://ferscloud.com/structural-analysis-javascript): `npm install @ferscloud/fers-calculation-web` — the solver compiled to WebAssembly, runs client-side with no server round-trip
