4 MCP Tools That Make Claude Code 10x Smarter (Context7, Sequential Thinking, Superpowers, Plan Mode)

Exact instruction

1. 1Four Claude Code add-ons. Research each before installing — do NOT install until each has been reviewed and approved:
2. 2Context7 MCP — feeds current library docs on demand. It's in the official Claude Code plugin marketplace (/plugin -> search 'Context7'); still confirm what it is and that it's the official one before installing.
3. 3Sequential Thinking MCP — adds a reasoning/pause layer. Find its GitHub repo and research who publishes it and whether it's safe.
4. 4Superpowers MCP — forces Claude to back up work before claiming done. Same research-first flow via its GitHub repo.
5. 5Plan Mode — built-in, nothing to install (Shift+Tab until 'plan mode' shows).
6. 6For the three MCPs, present the findings for review and install ONLY after explicit approval.

Adopt?

Yes: Context7 and Plan Mode are immediately actionable. Context7 prevents outdated API usage (high value). Sequential Thinking MCP is worth trying for complex multi-step tasks. Comment 'BUILD' on @simon.saysai's post for the install guide.
