Why we included this project

Multi-step agent workflows have a way of hiding how a model reached its answer. This MCP server keeps that reasoning visible: each thought is recorded as a numbered entry with per-session history, and you can branch or revise a plan while the server tracks how it evolved. The optional validation layer is the part worth calling out. If you pass in the list of tools available to the model, the server checks that any recommended tool names actually exist before storing the step, which catches hallucinated tool calls early. It does not discover or invoke your other MCP tools, so it works as a reasoning scratchpad inside an existing agent stack rather than replacing orchestration. For developers debugging long agent runs or wanting an auditable trail of how a plan took shape, it is a low-overhead addition.
