Thoughtbox

Overview

Thoughtbox is a Model Context Protocol (MCP) server: Extended reasoning with structured processes, persistence, and workflow guidance. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package @kastalien-research/thoughtbox speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v1.0.3, published under the MIT license, with source at Kastalien-Research/thoughtbox on GitHub, where it has earned 64 stars.

You'll find Thoughtbox in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
