Environment Variables

CANVAS_PROVIDER_TYPE(str)

Default:none

Set 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_URL(str)

Default:https://www.ebi.ac.uk/chembl/api/data

Base URL for the ChEMBL REST data API. Override for a private mirror or pinned host.

CHEMBL_REQUEST_TIMEOUT_MS(str)

Default:30000

Per-request timeout in milliseconds for upstream ChEMBL fetches.

CHEMBL_MAX_PAGE_SIZE(str)

Default:1000

ChEMBL per-page cap when streaming activity pages for the bioactivity spill (max 1000).

CHEMBL_DEFAULT_LIMIT(str)

Default:25

Default result limit applied when callers omit it.

CHEMBL_DATAFRAME_DROP_ENABLED(str)

Default:false

Set to 'true' to register the opt-in chembl_dataframe_drop tool (absent from tools/list when off).

MCP_LOG_LEVEL(str)

Default:info

Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').
