Environment / auth

MCP_LOG_LEVEL
Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').
INATURALIST_USER_AGENT
User-Agent sent on every request to api.inaturalist.org. Defaults to the package name, its version, and the repository URL. Keep a contact URL in any override — the published terms ask for identifiable clients.
INATURALIST_MIN_REQUEST_INTERVAL_MS
Minimum spacing between outbound request starts, in milliseconds. The default holds the sustained rate near 54 requests per minute, under the 60 the upstream asks for and well under its 100 ceiling.
INATURALIST_MAX_CONCURRENT_REQUESTS
Maximum outbound requests in flight. Separate from the start interval: spacing bounds the sustained rate, this bounds the burst so one slow call does not stall the lane.
INATURALIST_DAILY_REQUEST_BUDGET
Outbound requests allowed per UTC day, counted in-process. The default sits under the 10,000 per day the upstream asks for, and exhaustion fails loudly rather than degrading silently.
MCP_HTTP_HOST
The hostname for the HTTP server.
MCP_HTTP_PORT
The port to run the HTTP server on.
MCP_HTTP_ENDPOINT_PATH
The endpoint path for the MCP server.
MCP_AUTH_MODE
Authentication mode to use: 'none', 'jwt', or 'oauth'.
