What are common MCP server examples?
Common server categories expose documentation, approved files, databases, code-hosting data, tickets, or narrow business actions. Treat catalog listings as discovery, not endorsement.
Decision rule: Select a server by required capability, data sensitivity, permission scope, maintenance evidence, and recovery—not popularity alone.
Use it in a real situation
A support assistant needs product documentation and ticket context but must not update or close a ticket.
- Name the observable outcome and the constraint that changes the decision.
- Choose the smallest action that can produce useful evidence.
- Keep permissions, uncertainty, and side effects visible before execution.
- Run a check that could disprove the approach, then record what remains unknown.
Original ClaudeQuest worked example
From vague request to reviewable result
Task or input
Connect a read-only documentation resource and a read-only ticket query with explicit tenant and field filters.
Better result
The assistant can cite relevant context while write operations remain absent rather than merely discouraged.
How to verify it
Test an unauthorized tenant, excessive result size, unavailable upstream, revoked credential, and requested write action.
Three mistakes to avoid
Copying without adaptation. Replace repository, data, user, and authority assumptions with facts from your environment.
Treating prose as enforcement. Use permissions, validation, tests, and human approval for boundaries that must hold.
Calling one success proof. Re-test the decision with a different input or context before treating it as a durable skill.
