Lakexpress Mcp

arpe-io/lakexpress-mcp

This server wraps LakeXpress, a database export tool that syncs relational data to Parquet files in cloud storage. It exposes 14 subcommands through two main tools: preview_command for building CLI invocations with parameter validation, and execute_command with confirmation guards. You can initialize log databases, create sync configs, trigger exports, and check status across five source databases (SQL Server, PostgreSQL, Oracle, MySQL, MariaDB) and six storage backends including S3, GCS, and Azure. It also suggests workflows based on your source and destination, validates auth files, and reports capabilities. Reach for this when you need Claude to orchestrate database-to-lake pipelines with LakeXpress without manually constructing shell commands.
