 String logger,
 Object data)

Method Details

fromMap

public static McpLogMessage fromMap(Map<String,Object> params)

Parses a McpLogMessage from the contents of the 'params' object inside a 'notifications/message' message, presented as plain values.

level

public McpLogLevel level()

logger

public String logger()

dataAsJson

public String dataAsJson()

Returns the log payload as JSON text.

dataAsMap

public Map<String,Object> dataAsMap()

Returns the log payload as a plain map, so consumers do not need a JSON library.

Returns:

null when the payload is not a JSON object. MCP allows any JSON-serializable value here and a plain string is common, so use dataAsObject() to read those.

dataAsObject

public Object dataAsObject()

Returns the log payload as a plain JDK value: a String, a Map, a List, a boxed primitive, or null. MCP defines the payload as any JSON-serializable value, so this is the accessor that can represent all of them.
