Each quoted sentence is the first sentence of the publisher’s own description. The kind of tool and the “changes data” mark are our AI model’s reading of that description, not something we tested: two differently worded runs had to agree, otherwise no label is shown, and nobody has checked them by hand. A tool without the “changes data” mark is described as only reading, searching or calculating, or the two runs did not agree. No tool was called. Read the publisher’s full description before relying on it. “Publisher declares” lists the hints the server itself sends with the tool (MCP annotations: read-only, destructive, idempotent, open-world); they are the publisher's claims, not checked by us. Inputs are the parameters in the tool's own input schema: name, declared type, whether it is required, and the first sentence of its description. Read 2026-10-23.

How well are its tools described?

Features #4 and #5

How clearly this server's own tool descriptions say what a tool does, and how consistent its tool list is. The first part is an AI model's yes/no reading of each description; the second part is counted. We do not turn it into a grade.

Descriptions

AI reading of each description

Says what the tool does: 100% of 36 tools
Says what it returns: 100% of 36 tools
States limits, defaults or errors: 100% of 3 tools
Says when to use it: 100% of 36 tools
Items covered per tool: 4.0 of 4 on average

Counted from the listing

Parameters with a description: 100% of 278
Tools with a description: 100% of 36
Typical description length: 1,048 characters

The tool set

Counted from the listing

Tools: 36
Size of the list: about 21,504 tokens for an agent to load (characters ÷ 4)
Naming: 36 of 36 names use snake_case

AI reading: easy to mix up

No pair found.

The AI items cover 36 of 36 tools: for a tool where two differently worded runs disagreed, that item is left out. They were not checked by hand, and no tool was called. “Easy to mix up” means two tools whose names or descriptions overlap without saying how they differ; the AI found none. We do not rate whether the tool set is complete or whether side effects are spelled out, because our AI reading of those was not reliable enough.

How do I add it to my client?

Common questions about com.ferscloud/fers

Answered from the data above

Is com.ferscloud/fers safe to install?

We do not rate servers as safe or unsafe. 6 of its 9 applicable record checks are met (facts from public records, each listed on this page). What the records show: Its source repository opens publicly. Its repository had a push in the last 90 days. The listed version is the latest stable release. The package itself has no known vulnerability (OSV.dev). Its full dependency tree has no known advisory. 23 of its tools describe changing data (our AI model's reading of the descriptions). These are facts with their sources on this page, not a safety guarantee, and we did not run its tools.

Is com.ferscloud/fers free to use?

Its website (ferscloud.com/mcp) describes a freemium pricing model. This is an AI-classified reading of the page on 2026-10-23, so check the page itself before relying on it.

Has com.ferscloud/fers been security tested?

Partly. 4 of the 13 checks that apply to it were exercised. We started the package in an isolated sandbox and read what it declares, but this test round was read-only, so its tools were not called. No security verdict is published before verification.

What can com.ferscloud/fers do?

It lists 36 tools. In our AI model's reading of their descriptions (two runs had to agree, nobody checked it by hand), they include tools that read or search, create or change data, run code or commands and generate content. We did not call any tool, so this describes the text, not the behaviour.

Can com.ferscloud/fers change or delete data?

23 of its tools say in their description that they create, edit, delete, send or run something (our AI model's reading). We did not call any tool, so we cannot say what actually happens.

Does com.ferscloud/fers publish a security policy?

We found no SECURITY.md in its repository (root, .github/ or docs/) or in its owner's .github repository.

Is the listed version current?

Yes. The registry lists 2.1.0, the latest stable release on npm.

Where is the source code of com.ferscloud/fers?

In github.com/Jeroen124/FERS_core, which opens publicly.

Not probed (read-only run)

We started the package in an isolated sandbox and read what it declares, but this test round was read-only, so its tools were not called. No security score is given; a check we did not run is never counted as passed.
