SalaryNegotiationArena is an OpenEnv MCP environment where LLM agents learn salary negotiation by sparring with 5 AI hiring experts with hidden priorities and styles (analytical, aggressive, collaborative, bureaucratic, visionary). It runs on a Docker-isolated FastAPI MCP server exposing negotiation tools: propose, counter, accept, reject, walk_away. | Profile | Salary | Equity | Start | Priority | Balanced | 0.4 | 0.3 | 0.3 | Mix | Cash-heavy | 0.7 | 0.1 | 0.2 | Salary | Equity-heavy | 0.2 | 0.6 | 0.2 | Equity | Fast-start | 0.2 | 0.2 | 0.6 | ASAP Training uses GRPO (TRL) on Qwen2.5 with LoRA. Curriculum learning, self-play, and persona drift improve robustness, increasing deal success while reducing negotiation turns.
