Thoughtbox MCP Server

Multi-agent collaborative reasoning that's auditable. Thoughtbox is an MCP server for structured, multi-agent reasoning, with a companion web app for workspace and inspection flows. Every step is recorded as a structured thought in a persistent reasoning ledger that can be visualized, exported, and analyzed. It runs locally over stdio via the published package.

People connecting DevOps & monitoring tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
