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. 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 2026-10-31.

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

No AI reading was available for this server's tools (the two runs did not agree, or the listing was not reviewed).

Counted from the listing

Parameters with a description: 88% of 97
Tools with a description: 100% of 26
Typical description length: 302 characters

The tool set

Counted from the listing

Tools: 26
Size of the list: about 5,658 tokens for an agent to load (characters ÷ 4)
Naming: 26 of 26 names use snake_case

AI reading: easy to mix up

No pair found.

The AI items cover 0 of 26 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?

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.

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?

Feature #6

The 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.

Common questions about io.github.BlackCat-cyber-creator/x402-agent-hub

Answered from the data above

Who publishes io.github.BlackCat-cyber-creator/x402-agent-hub?

The registry ties the namespace io.github.BlackCat-cyber-creator to the GitHub account BlackCat-cyber-creator; only its owner can publish under it. Its linked repository, github.com/BlackCat-cyber-creator/x402-agent-hub-mcp, belongs to the same GitHub account. These are facts from the registry and GitHub, not a rating.

Is io.github.BlackCat-cyber-creator/x402-agent-hub 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.github.BlackCat-cyber-creator/x402-agent-hub need an API key or sign-in?

It opened a session without any credential on 2026-10-31. The registry entry declares no required credential; no declaration is not a guarantee.

Has io.github.BlackCat-cyber-creator/x402-agent-hub 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. ProtocolProbe publishes no security verdict for a named server.

Where is the source code of io.github.BlackCat-cyber-creator/x402-agent-hub?

In github.com/BlackCat-cyber-creator/x402-agent-hub-mcp, which opens publicly.

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.

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.
