codex-control-plane-mcp vs harvey
codex-control-plane-mcp: Codex Control Plane MCP transforms Codex Desktop and codex-app-server into a durable worker, enabling reliable automation for long-running tasks. It handles complex operations like retries, duplicate prompt protection, Plan Mode workflows, and approvals, abstracting away fragility from the client.; harvey: Harvey is an autonomous sales agent that finds businesses, learns something specific about each, writes and sends cold email, and works replies toward a meeting. It runs locally in a 15-minute loop using a Claude Code or Codex subscription instead of a per-token API bill, and by default every email waits for approval.
TL;DR
Automating long-running tasks with Codex Desktop without holding one MCP call open for hours.
Run outbound prospecting to small local businesses without Apollo or ZoomInfo
