stdio looked healthy. green badge in the IDE. tools/list was just [] . Agent kept calling search docs like it existed. I spent an hour chasing Cloudflare Workers cold starts before I noticed the hand…
put nightfall in front of cursor this week. $49/seat. first day it saved me — agent tried to cat a .env that was outside the docs allowlist and got a hard deny. second day it blocked a legit read on…
hit this thursday night. filesystem + github servers both "connected" in the UI. i opened the tools panel and got literally nothing. client still claimed handshake ok. restarted the app twice, nuked…
been running Nightfall MCP Gateway in front of Cursor + Claude Code for about a week. $20/mo out of pocket until the team notices. Tuesday it blocked notion.create page mid standup notes. fair. I had…

shipped a tiny internal MCP on friday so Claude Code could read Linear tickets. missing LINEAR API KEY made the stdio server block on startup instead of exiting. Claude sat on "calling tools…" for 22…
Had Nightfall MCP Gateway in front of Cursor + Claude Code since Tuesday. Mostly quiet. Friday 11pm our staging DB migration hung. Claude Code tried to call the shell MCP with psql ... DROP INDEX CON…
