Multi-LLM MCP server for Claude Code & Codex — route AI agent work across 20+ low-cost provider buckets with round-robin dispatch and quota-aware
Multi-LLM MCP server for Claude Code & Codex — route AI agent work across 20+ low-cost provider buckets with round-robin dispatch and quota-aware fallback.
Your Google + Groq + OpenRouter + Ollama Cloud free tiers, plus cheap direct APIs like DeepSeek, all have separate provider buckets. external-agents treats them as one pool: round-robin dispatch, cooldown-aware, auto-fallback on 429. Same agentic workload that used to cost $10-100/day on one premium model can often run at effectively $0-very-low-cost. Also the perfect substrate for LLM-Council-style multi-model panels — pick_agents gives you N distinct-provider picks in one call.
external-agents is one piece of Mrrlin — an AI orchestration platform for solo developers and small teams. If you like this package, you'll probably like the rest of Mrrlin.
