Observed fact
This server accepted a session without any credential and lists 11 tools whose name or declaration suggests they change data (ezrentout_create_customer, ezrentout_create_order, ezrentout_add_assets_to_order, ezrentout_book_order, ezrentout_add_order_custom_entry and 6 more). That is our reading of the names; we did not call them. Source: our connection, 2026-11-03.

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 2026-11-03.
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.

AI reading: easy to mix up
No pair found.
The AI items cover 0 of 59 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, comparing tools within groups of 40. 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.

- The server runs on the operator's infrastructure; it may ask you to sign in when you first connect.
- Zed's docs we read on 2026-10-26 describe remote servers by URL and do not name the transport.
- The MCP Inspector lists the server's tools, resources and prompts; a tool you call there runs for real.

Does the registry listing match what we found?
Feature #6The registry checks an entry when it is published (each new version), and nothing re-checks it on a schedule. A difference below is about the listing, not a judgement of the publisher.

Tool list changes
Our reads compared · no tool calledHosted endpoint ezrentout.usefulapi.io/mcp
No change in the tool list across 4 reads (2026-10-31 to 2026-11-03; versions 1.1.0 to 1.6.0).
Compared from the tool lists our read-only connection recorded, separately for each hosted endpoint and each package: each tool's name, title, description, input schema and annotations (the order of keys and of tools is ignored). We see a list only when we read it: a change is shown between the two reads where we first saw it, and anything after 2026-11-03 is not known yet. No tool was called. How it is compared

Read from public records only: the registry entry, npm/PyPI, GitHub and advisory databases, checked 2026-11-03 (security policy 2026-11-01). No tool was called. Only “met” and “not met” are counted, so the total differs between servers; a check that does not apply or that we could not run is listed, never counted against it. It is not a safety rating, and the same rules apply to every server. How each check works · Leaderboards · How we stay neutral
Common questions about io.usefulapi/ezrentout
Answered from the data aboveWho publishes io.usefulapi/ezrentout?
The registry ties the namespace io.usefulapi to the domain usefulapi.io; only its owner can publish under it. Its linked repository is github.com/m190/usefulapi-mcp; GitHub reports its owner as m190, a personal account. These are facts from the registry and GitHub, not a rating.
Is io.usefulapi/ezrentout safe to install?
We do not rate servers as safe or unsafe. 4 of its 5 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. These are facts with their sources on this page, not a safety guarantee, and we did not run its tools.
Does io.usefulapi/ezrentout need an API key or sign-in?
It opened a session without any credential on 2026-11-03. The registry entry declares no required credential; no declaration is not a guarantee.
Has io.usefulapi/ezrentout been security tested?
Partly. 3 of the 16 checks that apply to it were exercised. It accepted a session without any credential and lists tools whose names suggest they change data. We did not call them. ProtocolProbe publishes no security verdict for a named server.
Does io.usefulapi/ezrentout publish a security policy?
We found no SECURITY.md in its repository (root, .github/ or docs/) or in its owner's .github repository.
Where is the source code of io.usefulapi/ezrentout?
In github.com/m190/usefulapi-mcp, which opens publicly.

Reference
How is it classified?
18 fields
One value per field, each with its source. Fields written by AI models are marked. A field with no value says why.
“Not stated” means the source did not state it; “does not apply” means it does not apply to this kind of server; “our limit” means our own lookup failed. A linked value opens the directory filtered to the same value.

It shows this server's record-check count: facts from public records, no tool called. It is not a security rating or a pass. It links here and updates after each data reload.
Something wrong, or is this yours?
If a fact here is wrong, tell us and we will re-check it. If you operate this server, you can run our checks on it yourself with the free self-test command; we call no server’s tools ourselves for anything shown here.
