Anyone using Context7 MCP to avoid outdated docs in Claude?

I’ve been running into the same issue repeatedly when using Claude for coding: the model knows the concept, but the docs it references are slightly outdated or version-mismatched.

Context7 MCP seems to solve this by pulling documentation directly from official sources instead of relying on training data.

I’ve seen a lot of people mention it as one of the few MCPs that’s actually “always on” and worth the context cost — especially compared to search-based MCPs.

I started documenting MCPs (including Context7) with setup steps and usage notes so I don’t have to re-discover this every time.

Curious: - Are you using Context7 regularly? - Does it noticeably improve accuracy for you? - Any downsides you’ve run into?

(If helpful, I’ve written up the setup + notes here: https://ai-stack.dev)
