TLDers Domain Prices missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Is TLDers Domain Prices 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 271 ms. The bar chart above shows every period we have measured.

How do I connect TLDers Domain Prices?

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 TLDers Domain Prices need an API key?

No. TLDers Domain Prices completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is TLDers Domain Prices?

It answers our handshake in 271 ms on average, which is faster than 51% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use TLDers Domain Prices?

The npm package @tlders/mcp was installed 93 times in the last week. Week over week that is +110%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is TLDers Domain Prices open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
