Environment / auth

OPENSTATES_API_KEY
required
Open States API key from open.pluralpolicy.com. Required to make any API requests.
OPENSTATES_DAILY_REQUEST_BUDGET
Maximum upstream Open States requests per rolling 24 hours. Rejects before the request is issued once spent. Defaults to the v3 free-tier daily cap.
OPENSTATES_REQUEST_TIMEOUT_MS
Per-attempt upstream request deadline in milliseconds (minimum 1000). Expiry is non-retryable. Open States answers a scoped query in under a second to ~57s and its gateway gives up near 60s.
OPENSTATES_TOTAL_REQUEST_BUDGET_MS
Wall-clock ceiling in milliseconds for one call across every retry attempt and the backoff between them. Bounds a slow upstream that keeps failing retryably. Must be at least OPENSTATES_REQUEST_TIMEOUT_MS; startup rejects a lower value.
MCP_LOG_LEVEL
Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').
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'.
