Tool Overview¶

Nova ships with 26 built-in tools. The LLM decides which tools to call based on your request. You don't need to invoke them manually -- just describe what you want, and Nova handles the rest.

Connected MCP servers add more tools at runtime. Sub-agents receive neither MCP tools nor delegate_to_agent.
