Features and capabilities supported by this server

Functions exposed to the LLM to take actions

Name	Description
connect_sourceA	Register a data source (CSV file, Postgres database, or REST API). Credentials must be in environment variables or a YAML config file — never pass connection strings directly.
list_sourcesA	List all registered data sources and their connection status.
list_tablesA	List available tables across all sources, or just the named source.
get_schemaA	Return the column names and types for a specific table.
queryA	Execute a SQL query against a registered data source using DuckDB. Returns up to --max-rows rows (default 1000). In read-only mode (default), only SELECT statements are allowed. Use source='_all' to query across all CSV sources with cross-source joins. Supports limit and offset for pagination.
transformB	Apply aggregations, filters, renaming, or column selection to a source table and return or save results.
check_healthA	Check whether registered data sources are still reachable and responsive.
