How to run this locally with Claude? Error -32602

[palashkaria]

Hey everyone! I got the docker compose running and can access the server at http://0.0.0.0:23456/

the trouble is, when claude connects, it can find no tools. I went into the log & noticed an error code -32602 with the message Invalid request parameters.

Any clue what I might be doing wrong? I tried mcp-remote@latest in the claude config but no good.

Here's a snippet of the relevant part

What’s your Node version? I tried running it with version 18 and had the same issue. After updating to version 22, it worked fine. Let me know if it works for you.
