GadgetHumans Agent API Hub — questions

Answers built from our own checks of this server.

What can GadgetHumans Agent API Hub do?

It exposes 226 tools, read directly from the server on our last check. Among them: affiliate_search, age, agent_memory, agent_profile, air_quality, analyze_readability and 220 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 GadgetHumans Agent API Hub mostly used for?

Its tools cluster around json, color and generate. 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 GadgetHumans Agent API Hub 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 149 ms. The bar chart above shows every period we have measured.

Did GadgetHumans Agent API Hub ever remove tools?

Yes. betting_odds, crypto_price, cso_ireland, cso_statistics and 25 more 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 GadgetHumans Agent API Hub?

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 GadgetHumans Agent API Hub need an API key?

No. GadgetHumans Agent API Hub completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 226 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is GadgetHumans Agent API Hub?

It answers our handshake in 149 ms on average, which is faster than 85% 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.

Is GadgetHumans Agent API Hub open source?

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