# MemPalace via Docker Compose.
#
# The MCP server speaks JSON-RPC over stdio, so the `mcp` service is meant to
# be driven interactively (`docker compose run`), not left running detached:
#
#   docker compose build
#   docker compose run --rm mcp                       # MCP server over stdio
#   docker compose run --rm mcp cli search "GraphQL"  # one-off CLI command
#
# The named volume `mempalace-data` is mounted at /data and holds the palace,
# config, and the cached embedding model across runs.
