Official Lark/Feishu integration for messaging, group management, multidimensional tables, document search, and knowledge base queries.

• Supports five capability areas: instant messaging, chat group creation and management, Bitable (multidimensional table) CRUD operations, document search and import, and wiki node retrieval
• Document and knowledge base search require OAuth configuration; otherwise returns error 99991663
• Tools use hyphenated naming convention (mcp__lark-mcp__tool_name) and require careful parameter structure: path for URL parameters, params for query strings, data for request body
• Content fields must be JSON strings (single-quoted), filter values must be arrays, and token types vary by operation (doxcn for documents, wikcn for wiki nodes)
• Use useUAT: true for user-initiated resource creation and private data access; false for public data queries
