Why Claude keeps telling me to connect MCP to Google Drive etc?
@levelsio
These are not three separate concepts.
@RhysSullivan
This agentic coding crack is dangerous 😂 I lost an entire weekend because “just one more prompt” turned into shipping 3 major features with Relay. The scary part? It feels like cheating until you realize the real game is building proper harnesses and MCP servers so your agents don’t hallucinate permissions or leak context in production. That’s when the addiction becomes actually useful instead of just fun dopamine. Who else is completely hooked but also lowkey terrified of how fast this is moving? 😅
@AniketVarshne
Introducing: @meetgranola CLI/Claude Code Skill/OpenClaw and Hermes skill from the @ppressdev printed by @damienstevens . - Cross-meeting SQLite search - MEMO pipeline runner - Attendee timelines - Stop the MCP logged-out pain Really excited about this one. I can't live without @meetgranola I may have told @damienstevens I loved him when he submitted the PR to the Printing Press.
@mvanhorn
Today’s Figma MCP update makes it one of the strongest integrations with Claude Code I’ve seen. You can now use Claude Code to design in Figma with the the full context of your design systems.
