r/cursor on Reddit: Unable to use context7 MCP in cursor, pls help
May 5, 2025 -

I have 2 mcp servers in cursor:

  • Seq Thinking

  • Context7

Seq Thinking works no problem, but Context7 fails to connect no matter if i use npx, bun, or deno.
My node version is: v22.14.0
I don't know if i need bun or deno installed to try them out, or if they use node as well.

Here are the logs when starting context7:

2025-05-05 16:52:27.628 [error] ext7: No server info found

What am I doing wrong?

try using this then restart and let me know if it fails, then send sc of mcp.json "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp@latest"] }

r/cursor on Reddit: Noob question about MCP (specifically Context7)
March 31, 2025 -

I understand that Context7 is an MCP that pulls in the latest documentation for any library. I've added it in the MCP settings and I've generated some code with it by prompting "use context7 for the latest documentations on X".

Questions:
- Do I constantly need to be explicitly asking it to use context7 for every prompt, whether it's adding in a new library or if it's continuing off of a previous prompt?
- If yes to above, can I just add it to a systems prompt to always use the context7 MCP in every prompt? Will that become more expensive?

Not sure honestly if you always have to specify it, but I have it in one of my cursorrules files. I would make your rule specify that when you specify it (Cursor chat) should look up the documentation for something, it should look it up using the context7 mcp server. That shouldn't be expensive. Now if you are specifying it to use the docs for library X on every request, then it could get more expensive. Albeit, this depends on how Cursor membership requests work exactly... I just roll with it. If using your own API key for a model, it definitely will use more tokens if adding docs on every request versus conditionally saying when to use documentation.
