# Copy to .env and adjust as needed.

# --- MCP Server Mode ---
# "snapshot" = frozen archive DB (read-only tools only, runs locally)
# "tutorial" = live lightnet (read + write tools, all APIs)
# "live"     = read-only proxy to a public Mina network (no local infra)

# --- Live mode: which public Mina network to talk to ---
# Required when MINA_MCP_MODE=live. Stable: devnet, mainnet. Preflight: mesa.
# Preflight networks are not guaranteed to persist (may be reset/renamed without notice).
