Structured step-by-step reasoning

The Sequential Thinking MCP server is an Developer Tools Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents structured step-by-step reasoning. It exposes Sequential Thinking's capabilities as tools the AI can call directly from your editor or CLI.
The fastest way is the MCPizy CLI: run `mcpizy install sequential-thinking` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y @modelcontextprotocol/server-sequentialthinking` and restarting Claude Code.
Yes. The Sequential Thinking MCP server is free and open source (see the GitHub repository linked on this page). You may still need a Sequential Thinking account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.
Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
Once installed, your AI agent can structured step-by-step reasoning directly inside your conversation. Typical use cases include asking Claude Code or Cursor to run Sequential Thinking operations, inspect results, chain Sequential Thinking with other MCP servers (see our Workflow Recipes), and automate repetitive developer tools tasks without leaving your editor.
