Important Notes

Permission Boundaries (权限边界)

• All operations respect the user’s actual Lark permissions
• If a document is not accessible, you’ll receive a permission error
• Cannot access private documents or groups the user is not a member of

Document ID Extraction (文档ID提取)

Document URLs have this format:

• Docx: https://*.feishu.cn/docx/{document_id}
• Wiki: https://*.feishu.cn/wiki/{wiki_token}
• Sheets: https://*.feishu.cn/sheets/{spreadsheet_id}
• Bitable: https://*.feishu.cn/base/{app_token}

Extract the ID/token from the URL when accessing content.

Search Limitations (搜索限制)

• Maximum 50 results per search (count parameter)
• Use pagination (offset) for more results
• Search is case-insensitive
• Results are sorted by relevance

Content Format (内容格式)

• docx_v1_document_rawContent returns plain text (no formatting)
• @mentions are converted to display names based on lang parameter
• For rich formatted content, use the API to get structured data

Error Handling

Common errors and solutions:

1. “Permission denied” (权限被拒绝)

   • The user doesn’t have access to this document
   • Ask the document owner to grant permission

2. “Document not found” (文档未找到)

   • Document ID is invalid or document was deleted
   • Verify the document URL is correct

3. “Invalid token” (无效令牌)

   • MCP server authentication failed
   • Check LARK_APP_ID and LARK_APP_SECRET environment variables
   • Ensure OAuth token is valid

Tips for Effective Use

1. Start with search: Use keyword search before asking for specific documents
2. Be specific: Include relevant keywords to narrow down results
3. Use filters: Filter by document type or owner to find documents faster
4. Check permissions: Verify access before trying to read document content
5. Bilingual support: Works with both Chinese and English queries
