How MCP servers expose tools in the first place →
What is Atlarium Habitat Database MCP mostly used for?
Its tools cluster around calculate, plant and product. 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 Atlarium Habitat Database MCP 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 190 ms. The bar chart above shows every period we have measured.
How do I connect Atlarium Habitat Database MCP?
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 Atlarium Habitat Database MCP need an API key?
No. Atlarium Habitat Database MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 39 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Atlarium Habitat Database MCP?
It answers our handshake in 190 ms on average, which is faster than 70% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Atlarium Habitat Database MCP open source?
The code is open source: it is published under the MIT licence, written in TypeScript, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at mcp.atlarium.bio, which runs on its operator's own terms.
