What Are the Best Cursor Plugins to Install in 2026?

Cursor’s plugin marketplace, launched in February 2026, extends its coding agent beyond repository-based code generation by bundling rules, skills, subagents, commands, MCP servers, and hooks that connect it to live web data, external services, browser tools, and persistent workflows. The featured plugins span research and documentation through Firecrawl, GitHub-based issue, pull request, and CI access, structured development methods from Superpowers and pstack, branch review through Thermos, browser debugging via Chrome DevTools, production monitoring with Sentry, database work with Supabase, Vercel deployment management, Linear ticket workflows, Figma design integration, and cross-session memory through Supermemory. Plugins may follow the portable Agent Plugins standard or Cursor’s own format, and can be installed from chat with `/add-plugin` or through the Customize panel at user or project scope. The text recommends keeping only a small set enabled because each adds instructions and tools that consume context and may complicate tool selection, while reserving service-specific plugins for applicable projects. Although official marketplace plugins are open source and manually reviewed, users are advised to inspect permissions, hooks, and especially write access to production services before approving actions.
