Hex color to RGB 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.

How MCP servers expose tools in the first place →
What is Hex color to RGB mostly used for?
Its tools cluster around status and agent. 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 Hex color to RGB 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 118 ms. The bar chart above shows every period we have measured.
How do I connect Hex color to RGB?
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 Hex color to RGB need an API key?
No. Hex color to RGB completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 31 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Hex color to RGB?
It answers our handshake in 118 ms on average, which is faster than 94% 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 Hex color to RGB 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.
