Instance Method Details

#authenticate(request) ⇒ Object, ...

Authenticate a request using the custom handler. The handler receives a RequestContext, which supports hash-style access (request[:headers], request[:params]) for compatibility with handlers written against the legacy request hash. If the handler returns a Hash with a :user key, the value is extracted so that AuthManager receives the user data directly.

Parameters:

Returns:

  • (Object, nil, false) —

    user data or false if authentication failed. A return of nil (from { user: nil }) signals "authenticated, no user object."

def authenticate(request)
  result = @handler.call(VectorMCP::RequestContext.coerce(request))
  return false unless result && result != false

  return result unless result.is_a?(Hash) && result.key?(:user)

  result[:user]
rescue StandardError, NoMemoryError
  false
end

#configured? ⇒ Boolean

Returns:

  • (Boolean) —

    true if handler is present
