Type-safe Netease Yunxin / 网易云信 tools

Every response from the server is validated against Pydantic models. Use `create_account` and `update_account` knowing the data structure is verified at runtime. If the API returns a malformed payload, your agent raises an error immediately. You catch bad data before it hits your internal application logic.

Messaging with strict validation

Control your outgoing messages with precision. Your agent uses `send_p2p_message` to interact with users. The schema ensures your message format matches what the server expects. For large-scale alerts, `send_batch_message` behaves predictably. The runtime validation ensures your batch requests are formatted correctly every time.

Secure team management

Group operations are fully typed. Use `create_team` and `get_team_detail` to manage your chat structures. Your agent relies on the validated response to make its next move. Managing members with `add_team_member` or `kick_team_member` is straightforward. You get a clear result, and if anything fails, the agent knows why because of the strict validation.
