Worth knowing before you connect it

3 tools are described as changing something (kv_put, buy_lead_list, buy_market_report): our AI model's reading of the descriptions, not something we tested, and the server opened a session without any credential. We did not call them.

Each line comes from a section below, with its source and date.

What it mainly works on, as our AI model read its tool descriptions: accounts and data in outside web services.

3 of 45 tools are described as changing something (creating, editing, deleting, sending or running). For 5 the reading was uncertain, so no mark is 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 2026-10-23.

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 40 tools
Says what it returns: 100% of 40 tools
States limits, defaults or errors: 93% of 40 tools
Says when to use it: 100% of 40 tools
Items covered per tool: 3.9 of 4 on average

Counted from the listing

Parameters with a description: 91% of 102
Tools with a description: 100% of 45
Typical description length: 446 characters

The tool set

Counted from the listing

Tools: 45
Size of the list: about 11,058 tokens for an agent to load (characters ÷ 4)
Naming: 45 of 45 names use snake_case

AI reading: easy to mix up

No pair found.

The AI items cover 40 of 45 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.
The MCP Inspector lists the server's tools, resources and prompts; a tool you call there runs for real.

Built from the server's registry entry with each client's documented format (checked 2026-10-14; the Cursor link and the VS Code command 2026-10-19; the MCP Inspector command 2026-10-21). Values in < > are yours to fill in; this page never contains a key. Where the server needs a setting the entry does not declare, it can still fail to start.

Does the registry listing match what we found?

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.

Read from public records only: the registry entry, npm/PyPI, GitHub and advisory databases, checked 2026-10-22. 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.

Common questions about dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank/x402-bazaar-rank

Answered from the data above

Is dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank/x402-bazaar-rank safe to install?

We do not rate servers as safe or unsafe. 1 of its 2 applicable record checks are met (facts from public records, each listed on this page). What the records show: 3 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 dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank/x402-bazaar-rank free to use?

Its website (x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/join) describes a usage-based pricing model. This is an AI-classified reading of the page on 2026-10-23, so check the page itself before relying on it.

Does dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank/x402-bazaar-rank need an API key or sign-in?

It opened a session without any credential on 2026-10-23. The registry entry declares no required credential; no declaration is not a guarantee.

Has dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank/x402-bazaar-rank been security tested?

Partly. 2 of the 14 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.

What can dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank/x402-bazaar-rank do?

It lists 45 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, move money and calculate or convert. We did not call any tool, so this describes the text, not the behaviour.

Can dev.workers.x402-bazaar-rank-worker.x402-bazaar-rank/x402-bazaar-rank change or delete data?

3 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.

Active servers whose topic is also “finance-and-payments” and that have at least one tool of the same kind; most kinds in common first, then most GitHub stars. The topic and the tool kinds are an AI model's reading of the publishers' descriptions, not checked by hand. Similar is not a recommendation.

Security testing

What did we test, and what did we leave out?

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.
