Credentials it needs

NTFY_SERVERSJSON array of `{ baseUrl, authToken? | authUsername?+authPassword? }` entries — one per ntfy server. First entry is the default base. Auth is scoped to the entry's `baseUrl`; per-call `base_url` overrides that match a registered base forward that server's auth. Takes precedence over the single-server NTFY_BASE_URL / NTFY_AUTH_* shorthand.
NTFY_BASE_URLSingle-server shorthand — base URL of the ntfy server (no trailing slash). Used when NTFY_SERVERS is unset.
NTFY_DEFAULT_TOPICTopic used when a tool call omits `topic`. Treat the topic name as a secret — anyone who knows it can publish or subscribe.
NTFY_AUTH_TOKENBearer access token (`tk_…`) for the single-server shorthand. Mutually exclusive with NTFY_AUTH_USERNAME / NTFY_AUTH_PASSWORD.
NTFY_AUTH_USERNAMEBasic-auth username for the single-server shorthand — must be set together with NTFY_AUTH_PASSWORD.
NTFY_AUTH_PASSWORDBasic-auth password for the single-server shorthand — must be set together with NTFY_AUTH_USERNAME.
NTFY_REQUEST_TIMEOUT_MSPer-request HTTP timeout in milliseconds.
NTFY_MAX_RETRIESMax retry attempts for transient upstream failures (5xx, network, 429).
NTFY_BLOCK_PRIVATE_HOSTSWhen true, a per-call `base_url` override must resolve to a public address and its redirects are not followed. Servers registered under NTFY_SERVERS / NTFY_BASE_URL are exempt. Turn it on where callers you do not control can reach the server.
MCP_LOG_LEVELSets the minimum log level for output (e.g., 'debug', 'info', 'warn').
LOGS_DIRDirectory for file-based logs (Node only; ignored on Workers).
OTEL_ENABLEDEnable OpenTelemetry instrumentation (spans, metrics, completion logs).

MCP_SESSION_MODEHTTP session model: 'auto', 'stateful', or 'stateless'. This server requires 'stateful' over HTTP — the consent prompt on destructive and outbound calls is a multi-round-trip request that a 2025-era HTTP client can only complete over a live session — so an HTTP start with 'stateless' is refused. 'auto' resolves to 'stateful'; stdio ignores the setting.
MCP_HTTP_HOSTThe hostname for the HTTP server.
MCP_HTTP_PORTThe port to run the HTTP server on.
MCP_HTTP_ENDPOINT_PATHThe endpoint path for the MCP server.
MCP_AUTH_MODEAuthentication mode to use: 'none', 'jwt', or 'oauth'.
MCP_LOG_LEVELSets the minimum log level for output (e.g., 'debug', 'info', 'warn').
LOGS_DIRDirectory for file-based logs (Node only; ignored on Workers).
OTEL_ENABLEDEnable OpenTelemetry instrumentation (spans, metrics, completion logs).
