Useful MCP Servers

Purpose: identify the MCP server categories most useful to engineering teams

Official/source link: https://modelcontextprotocol.io/docs/getting-started/intro

Maintainer: category-level overview only

License: Varies by implementation

Last verified: 2026-07-14

Status: Documentation verified

Verification scope: protocol docs reviewed; category list is an editorial evaluation aid, not an approved implementation catalog

Category Typical value Main risk
GitHub PRs, issues, repo metadata, code review context repo write access and private code exposure
Browser / Playwright UI validation, screenshots, form flows account/session access and destructive clicks
Filesystem repo-local read/write workflows broad file access and shell-adjacent actions
Database / Postgres schema inspection and query help data leakage and destructive SQL
Jira / Bitbucket work tracking and SCM metadata token scope sprawl and ticket-data exposure
Slack / Teams alerting and collaboration context message history exposure and impersonation risk
Figma design context and handoff broad file and team access

Team Recommendation

Evaluate categories in this order:

  1. GitHub
  2. Filesystem
  3. Browser / Playwright
  4. Database or Postgres
  5. Ticketing and chat integrations

The first four categories usually provide the highest engineering value with the clearest approval questions.

What To Avoid Early

  • org-wide chat access
  • write-enabled production databases
  • MCP servers that proxy arbitrary shell execution
  • integrations with unclear maintainers or no revocation story

Verification Note

Use this page to prioritize evaluation, not to approve a server without implementation-level review.
