Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

categories
list_categories
List the twelve skill categories (free) with a short introduction and how many skills are listed in each. Use a slug as the category filter of search_skills.
redownload
redownload_skill
Re-download the SKILL.md file you already bought (free), using the token from your purchase receipt. Always returns the current version of the skill.
skill
get_skill
Get one skill card (free) plus the exact x402 payment_required body for its one-time purchase of the SKILL.md file, and how_to_buy. Price is price_usd on the card. Buying is over HTTP; MCP does not take payments.
skills
search_skills
Search the tested agent skill files for sale (free). Give a plain-language query (for example: sound less like ChatGPT), or filter by category, tag or language, or combine them. With a query the results come ranked by relevance; without one you get the featured skills first. Each card has match_reason (the field that matched, or the filter), price_usd (a one-time purchase of the SKILL.md file, yours forever), what it is for, what it is not for, and how it was tested. limit is at most 24.

AISkills402 — questions

Answers built from our own checks of this server.

What can AISkills402 do?
It exposes 4 tools, read directly from the server on our last check. Among them: get_skill, list_categories, redownload_skill, search_skills. 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 AISkills402 working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 1258 ms. The bar chart above shows every period we have measured.
Did AISkills402 ever remove tools?
Yes. execute_humanize, execute_humanize_long are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect AISkills402?
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 AISkills402 need an API key?
No. AISkills402 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is AISkills402?
It answers our handshake in 1258 ms on average, which is faster than 2% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
