What the sources write about this name

What the sources write about this name
MCP server in namespace io.githubSet to 'duckdb' to enable the bioactivity DataCanvas spill and the chembl_dataframe_* SQL tools. When 'none', large bioactivity sets inline a preview but never spill.
MCP server in namespace io.githubSet to 'duckdb' to enable DataCanvas (Node.js only). Registers the three eia_dataframe_* tools and lets eia_query_route stage rows when called with stage: true.
MCP server in namespace io.githubSet to 'duckdb' to enable DataCanvas spillover for large query result sets (Node.js only).
MCP server in namespace io.githubSet to 'duckdb' to enable the dataframe canvas, which lists the eurostat_dataframe_describe and eurostat_dataframe_query tools, lets eurostat_query_dataset stage a match larger than its 5,000-row inline cap as a SQL table, and lets eurostat_download_dataset retain a whole bulk download instead of only its inline preview. The DuckDB binding ships with the server, so this variable is the only switch.
MCP server in namespace io.githubSet to 'duckdb' to enable the DataCanvas SQL surface (default), or 'none' to disable analytical staging.
MCP server in namespace io.githubCanvas 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.
MCP server in namespace io.githubSet to 'duckdb' to enable DataCanvas SQL over large measurement series.
MCP server in namespace io.githubCanvas engine for DataCanvas SQL tools. Set to 'duckdb' to enable treasury_dataframe_* tools. Set to 'none' to disable.
