Once you know how to connect MCP, the next question is "what should I connect?" Here we organize the frequently recommended MCP servers of 2026 by use case. (These are examples, not a ranking; for the concept see What is MCP?)

Commonly used MCP servers by use case Dev • GitHub • Sentry • Supabase Database • PostgreSQL • SQLite Docs & PM • Notion • Linear • Jira Comms • Slack Browser & web • Playwright • Firecrawl Automation & pay • Zapier • Stripe Representative, frequently-recommended examples — not a ranking. The ecosystem changes fast (May 2026).

Representative servers by use case

  • Dev: GitHub (PRs, issues, code search), Sentry (error tracking), Supabase (DB/backend), Context7 (up-to-date library docs).
  • Database: PostgreSQL / SQLite connectors for direct queries.
  • Docs & project management: Notion (wiki/DB), Linear (issues/sprints), Atlassian/Jira (tickets).
  • Files & storage: Google Drive (cloud docs), Filesystem (local files).
  • Communication: Slack (summarize, search, post).
  • Browser & web scraping: Playwright (browser automation, Microsoft), Firecrawl (web scraping).
  • Business & payments: Stripe (payments), Shopify (commerce), HubSpot (CRM).
  • Automation: Zapier (hundreds of apps via one connection).

Many of these connect straight from the claude.ai connector directory (Google Drive, Slack, GitHub, Notion, etc.); the rest are added as custom connectors (Settings > Connectors) or in Claude Code (claude mcp add).

How to choose

  • Start with 2-3 you use daily. You don't need to add everything at once.
  • Don't add too many. Many note that going beyond 5-7 at once bloats the tool list and degrades the agent's decision quality.
  • Claude Code has built-in file tools, so a Filesystem MCP is usually redundant there.

Auth & security notes

  • Auth varies: OAuth login (Linear, Sentry), API key (Firecrawl), no-credential local (Playwright).
  • OAuth servers inherit your permissions — the agent can close real tickets or post messages as you, so start with read-only scopes.
  • Connect only trusted servers (official/verified). See the security check in the MCP connection guide.

Disclaimer: The MCP ecosystem changes very fast, and the list above is examples, not a ranking. A server's existence, name, features, pricing, and maintenance can change, so verify each server's official repo/docs and the claude.ai connector directory before installing.
