このサーバーについて

Sequential Thinking is a reference MCP server in the modelcontextprotocol/servers repository, kept by the MCP steering group. It offers one tool that a model calls again and again to lay out its reasoning as numbered thoughts: it estimates how many steps it needs, can revise an earlier thought, branch into an alternative line, or raise the count when the problem turns out larger. The server keeps the thought history for as long as the client stays connected. The README suggests it for planning, analysis that may need correction and problems whose scope is unclear at the start. It runs locally over stdio through npx or Docker, with setup for Claude Desktop, VS Code and Codex CLI.

できること

  • Record numbered reasoning steps with an adjustable total
  • Revise an earlier thought
  • Branch into alternative lines of reasoning
  • Extend the number of steps when more are needed
