How to Set Up and Use Sequential Thinking Tools
mcp-sequentialthinking-tools is an MCP server that implements structured sequential reasoning for AI agents, helping them break complex problems into explicit, inspectable thought steps while receiving recommendations about which MCP tools to use at each stage. It exposes three tools — sequentialthinking_tools, get_thinking_history, and clear_thinking_history — that act as a scratchpad and validator for multi-step problem solving. Developers use it alongside other MCP servers to guide Claude through methodical workflows, validate tool selection, and maintain a reviewable reasoning history across a session.
Prerequisites
- Node.js 18+ installed
- npm or npx available on your PATH
- An MCP-compatible client such as Claude Desktop
- One or more other MCP servers installed (to benefit from tool recommendations)
Test the server with npx
You can run the server directly without installing it using npx. This is useful to verify it works before adding it to your client configuration.
npx -y mcp-sequentialthinking-toolsAdd to Claude Desktop configuration
Edit your Claude Desktop config file at ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%/Claude/claude_desktop_config.json (Windows) to add the server.
{
"mcpServers": {
"mcp-sequentialthinking-tools": {
"command": "npx",
"args": ["-y", "mcp-sequentialthinking-tools"],
"env": {
"MAX_HISTORY_SIZE": "1000"
}
}
}
}Restart Claude Desktop
Fully quit and relaunch Claude Desktop so the new server is loaded. You should see the sequential thinking tools available in your Claude conversations.
Use the sequential-thinking-guidance prompt
The server ships with a built-in prompt called 'sequential-thinking-guidance'. In Claude Desktop, invoke it to get instructions on how to use the tool as a reasoning scratchpad rather than an external engine.
Sequential Thinking Tools Examples
Client configuration
Claude Desktop configuration for mcp-sequentialthinking-tools with optional MAX_HISTORY_SIZE environment variable.

}
}
}
}Prompts to try
Use these prompts to engage the sequential thinking tools for complex multi-step tasks.
- "Use sequential thinking to plan how to migrate this PostgreSQL database to a new schema."
- "Break down the steps needed to implement OAuth2 authentication in this Node.js app, and suggest which tools to use at each step."
- "Show me your thinking history for the last problem we worked on."
- "Clear the thinking history and start fresh on this new debugging task."Troubleshooting Sequential Thinking Tools
sequentialthinking_tools tool not appearing in Claude
Ensure npx can resolve the package by running 'npx -y mcp-sequentialthinking-tools' manually in your terminal. If it fails, check your npm registry connection. Then fully restart Claude Desktop after updating the config.
Thinking history is lost between Claude Desktop sessions
The history is stored per-session in memory only. MAX_HISTORY_SIZE controls how many thoughts are kept within a session (default 1000) but history does not persist across app restarts — this is by design.
Tool recommendations seem irrelevant or generic
The tool works best when other MCP servers are also installed and active, so it has context about what tools are available. Ensure your other MCP servers are correctly configured and restart Claude Desktop to load all servers together.
