Active·★ 12·MIT·Updated 2026-10-03

@putervision/behavior-mcp is a high-frequency (~60Hz) in-browser tactical runtime engine designed for AI agents, executing deterministic behavior trees with reactive trigger preemption. It features a 5-layer safety guardrail stack, frame recordings, and SHA-256 Merkle audit chains to ensure robust and auditable agent behavior within browser environments.

Features

01High-Frequency In-Browser Execution: Runs deterministic behavior trees directly in browser runtimes at approximately 60Hz.
02Reactive Trigger Preemption: Supports configuring reactive interrupt triggers with priority preemption for dynamic behavior changes.
035-Layer Safety Guardrail Stack: Implements robust safety mechanisms including fail-closed evaluators, action rate limiting, and an emergency kill switch.
04SHA-256 Merkle Audit Chains: Provides frame recordings and a SHA-256 Merkle audit ledger for verifiable and auditable behavior sequences.
05Comprehensive Tooling: Offers 10 core MCP tools for loading, managing, inspecting behaviors, parameters, and runtime state.
