Sequential Thinking

By Anthropic

Lets the model log a chain of reasoning steps as tool calls. Useful for hard problems where you want the steps to be inspectable — and to give a non-thinking model a budget for thought.

Install

Run directly:
$ npx -y @modelcontextprotocol/server-sequential-thinking
Add to claude_desktop_config.json:
{
  "mcpServers": {
    "sequential-thinking": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
    }
  }
}

What you can do with it

  • Have a non-thinking model show its work on a logic puzzle.
  • Plan a multi-step task before executing it.
  • Debug agent reasoning by reading the step log.
