Eurostat

Host a copy with our keys and logs.

• EUROSTAT_CLAMP_LIMITS — Clamp positive integer preview/search/dimension limits to 500/100/1000 with a notice. False restores schemas rejecting over-cap inputs.
• MCP_LOG_LEVEL — Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').
• EUROSTAT_BASE_URL — Eurostat API base URL. Override when using a mirror or proxy.
• EUROSTAT_COMEXT_BASE_URL — Base URL of the Comext dissemination host, which serves every DS-* dataset code (detailed trade and PRODCOM). Override when using a mirror or proxy.
• EUROSTAT_REQUEST_TIMEOUT_MS — Total allowance for one Eurostat request across retries, backoff and body consumption, in milliseconds.
• EUROSTAT_METADATA_TIMEOUT_MS — Total allowance for one dataset's SDMX dataflow structure across retries, backoff and body consumption, in milliseconds. Defaults to 120000; separate from EUROSTAT_REQUEST_TIMEOUT_MS for large structures.
• EUROSTAT_TOC_CACHE_TTL_MS — How long a fetched catalogue TOC stays usable before the next catalogue call refreshes it, in milliseconds. Defaults to 12 hours.
• EUROSTAT_BULK_TIMEOUT_MS — Total allowance for one eurostat_download_dataset transfer across request retries, backoff and streaming body consumption, and for each download that builds the dimension value index, in milliseconds. Defaults to 120000.
• EUROSTAT_BULK_MAX_BYTES — Byte budget for one eurostat_download_dataset transfer, counted on the decoded TSV rather than on the wire. Eurostat sends the body chunked with no Content-Length, so the budget is enforced while streaming and the transfer is aborted when it is reached. Defaults to 50 MiB.
• CANVAS_PROVIDER_TYPE — Dataframe canvas backend. The default, 'duckdb', lists eurostat_dataframe_describe and eurostat_dataframe_query, stages query matches with stage=true or above 5,000 observations, and retains bulk downloads beyond their previews. Set to 'none' to disable the canvas and those tools. The DuckDB binding ships with the server.
• CANVAS_TEMP_PATH — Parent directory for DuckDB canvas spill files: a private 'mcp-canvas-XXXXXX' directory is created inside it, so it must be writable by the server process. Defaults to the OS temp directory.
• CANVAS_TTL_MS — Sliding lifetime of a staged dataframe canvas in milliseconds; every call against it extends the window. Defaults to 24 hours.
• CANVAS_DEFAULT_ROW_LIMIT — Maximum complete rows a single eurostat_dataframe_query returns before reporting truncated.
• EUROSTAT_DATAFRAME_DROP_ENABLED — Set to 'true' to list eurostat_dataframe_drop, which removes one staged table from a dataframe canvas and leaves its other tables in place. Off by default because a drop cannot be undone; staged tables expire with their canvas either way. Has no effect with CANVAS_PROVIDER_TYPE=none.
