Nothing serious here today

Today is the operative word: we check Graunt every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Graunt — questions

Answers built from our own checks of this server.

What can Graunt do?
It exposes 9 tools, read directly from the server on our last check. Among them: fetch, get_agent_commerce_manifest, get_asset, get_asset_manifest, get_bundle_manifest, meta_capabilities and 3 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 Graunt mostly used for?
Its tools cluster around asset and meta. 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 Graunt 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 462 ms. The bar chart above shows every period we have measured.
How do I connect Graunt?
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 Graunt need an API key?
No. Graunt completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Graunt?
It answers our handshake in 462 ms on average, which is faster than 34% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
