Claude Code HTTP transport

[timkjr]

HI all,

I have been trying and trying to get Claude Code to connect to this MCP via http transport, and no matter what I do I get "Cannot connect" and complaints about either tokens or "Method not allowed" in Claude's logs depending on what I'm trying with OAuth. I've tried with and without OAuth (I'd prefer without). I've tried with and without https. I've tried setting API_KEYs and OAUTH_KEYs and telling Claude to use an Authorization: Bearer header. Nothing and nothing are working.

I have scoured the Troubleshooting, FAQ, Claude Code WIKI, Issues, Integration Guide, Advanced Configuration, everything that seems to relate. Nothing is working. Please, please offer me a new direction to try!

And a second question -- I'm confused because running the MCP via systemd, it's not creating log files I can find, NOR putting anything into journalctl. Again -- what am I missing?

Discovered that Claude Code's MCP SDK barfs on the current version's returned JSON which included '"error": null' in successful responses. A simple fix to strip that out and it works! I'm submitting as a PR.
