HTTP transport. Works with Claude.ai, Claude Code, Cursor, OpenClaw, Continue, Cline, Windsurf, Goose, n8n, and any HTTP-capable MCP client.
Batch operations. batch_update_events updates up to 50 events in one concurrent call.
Multi-account, one key. Connect any number of Google accounts (mix OAuth + service-account-shared calendars) under a single API key. Reading fans out across all of them.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
