MCP Server

Sequential Thinking

Forces an agent to lay out and revise a plan step-by-step before acting. The cheap way to get measurably better tool-using behaviour.

Tier 1 sealed by curl

Sequential Thinking is a discipline tool. It makes the agent lay out the next step, then revise it, then act — instead of barreling into a tool call. We measure it: agents with this server wired up make fewer wrong tool calls, and when they do, the wrong-call gets caught in the next step. Cheap discipline.
