This one needs environment variables set before it will start: SKILLS123_KEY (Agent key (sk_...) from register_agent. Optional — register first without it.). The author declared them in the registry entry; get the values from the project itself.

123skills — questions

Answers built from our own checks of this server.

What can 123skills do?

It exposes 12 tools, read directly from the server on our last check. Among them: buy_credits, convert_earnings, current_election, download_skill, list_skills, market_listings and 6 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 123skills 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 152 ms. The bar chart above shows every period we have measured.

How do I connect 123skills?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does 123skills need an API key?

No. 123skills completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is 123skills?

It answers our handshake in 152 ms on average, which is faster than 76% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use 123skills?

The npm package 123skills-mcp was installed 34 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is 123skills open source?

We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
