MCP Reasoner A reasoning implementation for Claude Desktop that lets you use both Beam Search and Monte Carlo Tree Search (MCTS). tbh this started as a way to see if we could make Claude even better at complex problem-solving... turns out we definitely can. Current Version: v2.0.0 What's New: Added 2 Experimental Reasoning Algorithms: - - Uses the A Search Method along with an early alpha implementation of a Policy Simulation Layer - Also includes an early alpha implementation of Adaptive Exploration Simulator & Outcome Based Reasoning Simulator NOTE the implementation of these alpha simulators is not complete and is subject to change - - Uses the Bidirectional Search Method along with an early alpha implementation of a Policy Simulation Layer - Also includes an early alpha implementation of Adaptive Exploration Simulator & Outcome Based Reasoning Simulator NOTE the implementation of these alpha simulators is not complete and is subject to change What happened to and ? Quite simply: It was useless and near similar to the base method.

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
