search_and_generate · Doubao Seedream MCP: Risk & Policy

WHAT IT DOES

What search_and_generate does on Doubao Seedream

AI agents invoke search_and_generate to trigger actions in Doubao Seedream. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why search_and_generate needs a policy

This tool performs two external operations: it searches the internet and then triggers image generation. The internet search constitutes an external operation with unpredictable side effects (network calls, data retrieval from external sources), and the image generation produces an external artifact. This combination of triggering external operations classifies it as Execute.

From the tool's definition 'Generate image with web search enabled. Model searches internet for up-to-date info to improve generation.'
