Sequential Thinking is an unusual MCP server: it doesn't talk to any external service. Instead, it provides a single think tool that prompts the model to record a numbered sequence of intermediate thoughts before producing a final answer.
That sounds trivial, but in practice it meaningfully improves reasoning on hard tasks — debugging, planning, multi-step refactors — because the model can revise earlier steps and the chain of reasoning is explicit and inspectable.
It is a reference for what "thinking tools" look like in MCP. Worth pairing with task-execution servers when you want planned-then-executed behavior.
