- Supports mainnets (Ethereum, BSC, Polygon, Arbitrum, Avalanche, Base, Fantom, Gnosis, Linea, Optimism, and more) and testnets (Sepolia, Holesky, Base Sepolia, Avalanche Fuji, etc.)
- Runs locally via SSE or as a remote server with per‑connection isolation
- Can be deployed and accessed via a URL with an API key for authentication

Local development
Install dependencies
pnpm i
Run local SSE server
export ANKR_API_KEY="YOUR-ANKR-KEY"
pnpm dev:sse
Remote server
In the remote mode service creates an isolated MCP Server instance for each connection, enabling secure and isolated access over the internet. Each connection requires an apiKey in the URL path for authentication with Ankr Advanced API.
