Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

Skill Market — questions

Answers built from our own checks of this server.

What can Skill Market do?

It exposes 59 tools, read directly from the server on our last check. Among them: a2a_bridge_info, a2a_discover, a2a_message_send, a2a_tasks_cancel, a2a_tasks_get, bankr_quote and 53 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 →

What is Skill Market mostly used for?

Its tools cluster around sco, a2a and memory. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Skill Market working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 201 ms. The bar chart above shows every period we have measured.

Is Skill Market still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Skill Market?

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 Skill Market need an API key?

No. Skill Market completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 59 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Skill Market?

It answers our handshake in 201 ms on average, which is faster than 67% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
