MODEL CONTEXT PROTOCOL (MCP) READINESS

⚠ Nemotron 3 Content Safety does not natively advertise tool-calling capabilities. When connecting to MCP servers, function calling must be handled via structured prompt injection.

MCP Context Window Recommendations

With a context capacity of 128,000 tokens, this model can handle moderately large MCP tool definitions and multi-turn conversation logs comfortably.
