What the code does

A tool parameter reaches a dangerous call

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

A tool parameter here reaches a dangerous call

That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

Chp — questions

Answers built from our own checks of this server.

What can Chp do?
It exposes 9 tools, read directly from the server on our last check. Among them: define, explain, faq, get_capability, get_example, how_to_adopt and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Chp working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 27 of 91 checks got a reply (29.7%), average response time 405 ms. The bar chart above shows every period we have measured.
How do I connect Chp?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Chp need an API key?
No. Chp completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Chp?
It answers our handshake in 405 ms on average, which is faster than 31% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Chp open source?
The code is open source: it is published under the Apache-2.0 licence, written in Python and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at capabilityhostprotocol.com, which runs on its operator's own terms.
