Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command fers_core/run_examples.py:45, fers_core/cli.py:594 
    proc = subprocess.run(
Dumps the whole environment fers_core/cli.py:593 
    env = dict(os.environ, PYTHONIOENCODING="utf-8")

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

FERS — structural FEM — questions

Answers built from our own checks of this server.

Why is there no tool list for FERS — structural FEM?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is FERS — structural FEM working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 162 ms. The bar chart above shows every period we have measured.
How do I connect FERS — structural FEM?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to FERS — structural FEM?
No API key is involved. FERS — structural FEM answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is FERS — structural FEM?
It answers our handshake in 162 ms on average, which is faster than 79% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use FERS — structural FEM?
The npm package @ferscloud/fers-mcp was installed 972 times in the last week. Week over week that is +69%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is FERS — structural FEM open source?
No, and the distinction matters: it ships its own licence file rather than a standard open-source licence. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
