• OSM_NOMINATIM_BASE_URL — Nominatim API base URL. Override to use a private or mirror instance.
• OSM_USER_AGENT — User-Agent sent to Nominatim and Overpass. Required by usage policy.
• OSM_OVERPASS_BASE_URL — Overpass API endpoint URL. When set, pins every query to this one endpoint and disables mirror failover; OSM_OVERPASS_MAX_CONCURRENCY sizes it and a |N suffix is rejected. Leave unset to use OSM_OVERPASS_ENDPOINTS.
• OSM_OVERPASS_ENDPOINTS — Comma-separated ordered list of Overpass endpoints. A failure advances to the next entry within the same tool call; a single entry means no failover. An entry written url|N gets N slots of its own and adds capacity, for an instance whose operator allows parallel queries, never a public instance such as the FOSSGIS servers, maps.mail.ru, or overpass.private.coffee; an unsuffixed later entry is failover only. Write a | inside a URL as %7C. Verify a mirror's usage policy, data coverage, and freshness before adding it. Ignored when OSM_OVERPASS_BASE_URL is set.
• OSM_OVERPASS_MAX_CONCURRENCY — Concurrent Overpass queries per endpoint: OSM_OVERPASS_BASE_URL, and every OSM_OVERPASS_ENDPOINTS entry not sized with |N. With no |N entry it is also the most queries in flight across all endpoints. A query waits at most 30 seconds in total for a slot, then fails with pacer_shed and a retryAfter. The default of 1 follows the public FOSSGIS instances, which allow one query in flight per user; raise it only for an instance whose operator allows parallel queries, such as a private or paid one.
• MCP_LOG_LEVEL — Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').
