# aldabra — Cardano lite wallet over MCP.
|
|
#
|
|
# Multi-stage:
|
|
# 1. builder — rust toolchain, cargo build --release
|
|
# 2. runtime — debian:bookworm-slim, just the binary + ca-certs.
|
|
#
|
|
# Produces an `aldabra/mcp` image with the MCP-server binary baked in.
|
|
# Pulled anywhere the MCP server is needed — usually as a sidecar
|
|
# spawned by an MCP client (Claude Code, etc).
|
|
#
|
|
# Required env at runtime:
|
|
# ALDABRA_DATA directory containing mnemonic.age (must
|
|
# already exist; bootstrap separately on
|
|
# first install)
|
|
# ALDABRA_NETWORK mainnet | preview | preprod (default preprod)
|
|
# ALDABRA_KOIOS_BASE defaults to public Koios for the network
|
|
# ALDABRA_PASSPHRASE unlocks mnemonic.age. Source from a docker
|
|
# secret or systemd EnvironmentFile — never
|
|
# commit it.
