You have access to a streamable HTTP MCP server designed for step-by-step problem solving, where you can think through problems, revise previous thoughts, and explore multiple approaches while preserving context across steps. This server is ideal for building AI-assisted workflows that require careful planning, revision, and branching as understanding deepens.

How to use

Connect your MCP client to the server to start a session and begin sending messages that represent your thinking steps. Use the main MCP endpoint to initialize sessions, call the dynamic thinking tool, and manage session lifecycle. While you work, you can revise earlier thoughts, branch into alternative approaches, and request additional thoughts as needed. The server streams notifications to you so you can observe progress in real time.

Practical usage patterns include starting with an initial plan, submitting a first thought, indicating whether more thoughts are needed, and then deciding whether to revise or branch based on how the problem unfolds. Maintain context across steps so that subsequent thoughts reference earlier conclusions. You can terminate a session when you have completed your process.

How to install

Prerequisites: Node.js and npm installed on your machine.

1. Set up the server locally by installing dependencies and starting it.

2. Optionally configure the port via the PORT environment variable if you need a non-default port.
