What it does
This tool lets a Kimi-powered agent search the web when you add Kimi Web Search to the agent. Search only runs when the tool is enabled. Results are encrypted by Kimi so only the model can read them. Traces show that the search completed, but not the result list. The tool is available only with Moonshot models such askimi-k3 and kimi-k2.6.
Adding the tool to an agent
- Open an agent that uses a Kimi (Moonshot) model.
- Click the button with the tooltip Add MCP Tool or Sub Agent.
- In MCP Tools, click Kimi Web Search.
Billing
Kimi Web Search is billed as a hosted LLM tool completion (similar to Sonar Web Search and Anthropic Web Search), not against the provider-tool daily cap used by SERP API or Google Search. Each successful search costs a fixed web-search call fee plus the tokens used to read the search results.Related
