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

Verification scope: protocol docs reviewed; category list is an editorial evaluation aid, not an approved implementation catalog
Recommended Categories
| 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:
- GitHub
- Filesystem
- Browser / Playwright
- Database or Postgres
- 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.
