Evaluate MCP servers by workflow, official vs community, and transport. A free instant guide with trust and safety tips for granting access, no download required.

By 2026, hundreds of MCP servers exist — some official, many community. Picking the right ones for your setup is mostly about three questions: workflow, trust posture, hosting. Here’s the framework.

Question 1: what does your AI agent need to do?
- Coding: Filesystem, Git, GitHub, Sequential Thinking, Memory.
- Research: Brave Search, Fetch, Memory, Filesystem.
- Data analysis: Postgres, SQLite, Filesystem, Memory.
- Customer support: Slack, Notion, Linear, Memory.
- PM / ops: Linear, Notion, Slack, GitHub, Google Drive.
Question 2: official or community?
- Official (modelcontextprotocol/* + vendor-published): SOC 2 review usually possible, source maintained, breaks fixed.
- Community: often higher feature velocity, but vary in quality + abandon risk.
- Heuristic: use official for anything reading sensitive data; community is fine for additive tooling.
Question 3: stdio or HTTP?
- stdio: local-only, simpler, no network exposure. Default choice.
- HTTP/SSE: remote-deployable, multi-user. Required if your agent runs in cloud.
Trust + safety
- Read the source for any community server before granting filesystem or network access.
- Treat MCP servers as having user-level privileges. They CAN read your files.
- Use scoped credentials — tokens with minimal permissions.
- Audit access logs periodically (Anthropic + OpenAI both expose them).
