Credentials it needs

CANVAS_PROVIDER_TYPESet 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.
CHEMBL_API_BASE_URLBase URL for the ChEMBL REST data API. Override for a private mirror or pinned host.
CHEMBL_REQUEST_TIMEOUT_MSPer-request timeout in milliseconds for upstream ChEMBL fetches.
CHEMBL_MAX_PAGE_SIZEChEMBL per-page cap when streaming activity pages for the bioactivity spill (max 1000).
CHEMBL_DEFAULT_LIMITDefault result limit applied when callers omit it.
CHEMBL_MAX_SPILL_ROWSCeiling on rows chembl_get_bioactivities stages to a DataCanvas table, and so on the upstream page drain behind it. Over the cap the response reports truncated: true.
