MCP.Pizza Chef: upstash
Coding assistants often answer from months-old memory, inventing functions that were renamed or never existed at all. Context7 pulls the real documentation and working examples for the exact library version you name, then drops them into the answer as it is written. Add the words 'use context7' to a prompt in Cursor, VS Code, Claude Desktop, Windsurf or Zed. There is a hosted address so nothing has to run on your machine, and a free key raises the usage limits.

Do I need an account or key?
You can start without one, but a free key from context7.com gives you higher usage limits.

Yes — ask your question and add 'use context7', and current examples come back with the answer.
How hard is setup?
You paste a short block of settings into your editor, or click the install button in Cursor or VS Code.
Does it cover the library I use?
It covers thousands of popular projects, and anyone can submit one that is missing.

No — you can point at the hosted address instead, though running it locally needs Node 18 or newer.
