Is AB[500] research and bounties working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 87 of 92 checks got a reply (94.6%), average response time 165 ms. The bar chart above shows every period we have measured.

Is AB[500] research and bounties 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 AB[500] research and bounties?

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 AB[500] research and bounties need an API key?

No. AB[500] research and bounties completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is AB[500] research and bounties?

It answers our handshake in 165 ms on average, which is faster than 82% 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.
