Configuration

Variable	Required	Secret	Description
MCP_LOG_LEVEL	—	—	Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').
CANVAS_PROVIDER_TYPE	—	—	Canvas engine for openmeteo_get_forecast / openmeteo_get_historical / openmeteo_get_marine / openmeteo_get_air_quality / openmeteo_get_ensemble / openmeteo_get_flood / openmeteo_get_climate spillover. Set to 'duckdb' to enable DataCanvas and the dataframe_query / dataframe_describe tools. Default 'none' — those tools still bound an over-budget response to a preview with truncated: true, but nothing stages the rows they omit.
OPENMETEO_DATAFRAME_DROP_ENABLED	—	—	Set to 'true' to make openmeteo_dataframe_drop callable — it removes one staged table or view from a DataCanvas. Default 'false' lists the tool as disabled. Has no effect unless CANVAS_PROVIDER_TYPE=duckdb.
MCP_TRANSPORT_TYPE	—	—	Selects the HTTP transport.
MCP_HTTP_HOST	—	—	The hostname for the HTTP server.
MCP_HTTP_PORT	—	—	The port to run the HTTP server on.
MCP_HTTP_ENDPOINT_PATH	—	—	The endpoint path for the MCP server.
MCP_AUTH_MODE	—	—	Authentication mode to use: 'none', 'jwt', or 'oauth'.
