tap vs behavior-mcp

tap: Taprun is an AI-powered action layer that allows agents to drive your own logged-in browser for complex web interactions that clean APIs cannot reach. It compiles web interactions into deterministic .plan.json programs once, enabling subsequent replays at zero LLM tokens and ensuring local-first execution for privacy and security.; behavior-mcp: @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

tap logotap
01AI compiles web actions once into a deterministic plan, allowing infinite replays without consuming LLM tokens.
02Local-first architecture ensures cookies, login sessions, and data remain on your machine for enhanced privacy.
03Provides deterministic replay with `tap verify` to detect silent failures and drift over time.
04Seamlessly integrates with popular AI coding agents and IDEs like Claude Code, Cursor, and VS Code.
behavior-mcp logobehavior-mcp
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.
