Usage of AI Gateway External Processor:
  -adminPort int
    	HTTP port for the admin server (serves /metrics and /health endpoints). (default 1064)
  -configBundlePath string
    	path to the sharded configuration bundle directory (index.yaml + parts).
  -enableRedaction
    	Enable redaction of sensitive information in debug logs.
  -endpointPrefixes string
    	Comma-separated key-value pairs for endpoint prefixes. Format: openai:/,cohere:/cohere,anthropic:/anthropic,typesafe:/typesafe.
  -extProcAddr string
    	gRPC address for the external processor. For example, :1063 or unix:///tmp/ext_proc.sock. (default ":1063")
  -logFormat string
    	log output format for the external processor. One of 'text' or 'json'. (default "text")
  -logLevel string
    	log level for the external processor. One of 'debug', 'info', 'warn', or 'error'. (default "info")
  -logRequestHeaderAttributes value
    	Comma-separated key-value pairs for mapping HTTP request headers to access log attributes. Format: agent-session-id:session.id,x-tenant-id:tenant.id. Default: agent-session-id:session.id (when unset). Set to empty to disable.
  -maxRecvMsgSize int
    	Maximum message size in bytes that the gRPC server can receive. Default is unlimited since the flow control should be handled by Envoy. (default 9223372036854775807)
  -mcpAddr string
    	the address (TCP or UDS) for the MCP proxy server, such as :1063 or unix:///tmp/ext_proc.sock. Optional.
  -mcpFallbackSessionEncryptionIterations int
    	Number of iterations used in the fallback PBKDF2 key derivation for MCP session encryption. (default 100000)
  -mcpFallbackSessionEncryptionSeed string
    	Optional fallback seed used for MCP session key rotation.
  -mcpSessionEncryptionIterations int
    	Number of iterations to use for PBKDF2 key derivation for MCP session encryption. (default 100000)
  -mcpSessionEncryptionSeed string
    	Seed used to derive the MCP session encryption key. This should be changed and set to a secure value. (default "default-insecure-seed")
  -mcpWriteTimeout duration
    	The maximum duration before timing out writes of the MCP response (default 2m0s)
  -metricsRequestHeaderAttributes value
    	Comma-separated key-value pairs for mapping HTTP request headers to otel metric attributes. Format: x-tenant-id:tenant.id,x-tenant-id:tenant.id.
  -requestHeaderAttributes value
    	Comma-separated key-value pairs for mapping HTTP request headers to otel attributes shared across metrics, spans, and access logs. Format: x-tenant-id:tenant.id.
  -rootPrefix string
    	The root path prefix for all the processors. (default "/")
  -spanRequestHeaderAttributes value
    	Comma-separated key-value pairs for mapping HTTP request headers to otel span attributes. Format: agent-session-id:session.id,x-tenant-id:tenant.id. Default: agent-session-id:session.id (when unset). Set to empty to disable.
