MCP Router: maxJsonDepth

maxJsonDepth limits nesting in the parsed JSON-RPC request value.

• Type: Positive integer
• Default: 128

Arrays, objects, and scalar leaves each contribute to the recursive depth. A request exceeding the limit returns HTTP 400 and JSON-RPC code -32600. This protects runtime request parsing; schema-document complexity is governed separately by schema.maxDepth and schema.maxSubschemas.
