Mcp Server
Routes your AI agent's API calls to the cheapest available service for each task. Instead of hardcoding providers, your agent calls generic capabilities like geocoding or translation, and Hebline picks between free options (Nominatim, MyMemory) and paid ones (Google Maps, DeepL) based on weighted scoring. Supports BYOK for paid services via environment variables. Logs every call with cost and latency to a local JSONL file. Exposes three MCP tools: execute to route and call, compare to preview available services, and categories to list supported capabilities. Currently covers nine categories including LLMs, geocoding, translation, web scraping, and weather. Roadmap includes Hebbian learning to optimize routing based on historical performance.

Hebline MCP Server
Your agents overpay for every API call. We fix that.
Hebline routes every API call — including LLM calls — to the best service at the right price. Free when it's enough. Paid when it matters. It knows the difference.
Every other router earns a margin on your paid calls. Routing you to free alternatives kills their revenue. No margin on your API calls. Ever.
Why Hebline?
Your agents are bleeding money. One task triggers 5–10 paid API calls across different providers. No transparency, no cost control. Hebline fixes that:
