Looked for and not found: deprecated in the registry; repository link does not open; repository archived; no push in over 365 days. Does not apply: listed version cannot be installed or is withdrawn. Each line is a dated fact from a public record. It does not say whether the server still works, and a record can change after the date shown.

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 2026-10-27.

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 5 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.

Does the registry listing match what we found?

Feature #6

The registry verifies a package once, when it is published, and does not re-check it. A difference below is about the listing, not a judgement of the publisher.

No change in the tool list across 2 reads (2026-10-26 to 2026-10-27; versions 1.0.0 to 1.1.0).

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 2026-10-27 is not known yet. No tool was called. How it is compared

Common questions about io.usefulapi/ticketsauce

Answered from the data above

Who publishes io.usefulapi/ticketsauce?

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/ticketsauce safe to install?

We do not rate servers as safe or unsafe. 4 of its 4 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/ticketsauce need an API key or sign-in?

It opened a session without any credential on 2026-10-27. The registry entry declares no required credential; no declaration is not a guarantee.

Has io.usefulapi/ticketsauce been security tested?

Partly. 3 of the 16 checks that apply to it were exercised. We connected and read what the server declares, but did not call its tools: ProtocolProbe calls no server's tools for anything it publishes. This is our choice, not a block by the server. No security verdict is published before verification.

Where is the source code of io.usefulapi/ticketsauce?

In github.com/m190/usefulapi-mcp, which opens publicly.

Security testing

18 checks · features #1, #2

Not probed (we call no server's tools)

We connected and read what the server declares, but did not call its tools: ProtocolProbe calls no server's tools for anything it publishes. This is our choice, not a block by the server. No security score is given; a check we did not run is never counted as passed.

ProtocolProbe: 4 of 4 record checks met

[![ProtocolProbe](https://protocolprobe.com/api/v1/badge/io.usefulapi/ticketsauce)](https://protocolprobe.com/mcp/servers/io.usefulapi/ticketsauce)

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.
