Tencent Drive MCP

Problem

When an agent needs to read, organize, or move files in Tencent Drive, raw web APIs usually lack a clean protocol and expose brittle details such as pdir_key, two-phase upload, chunked SHA1, and token authentication. Tencent Drive MCP wraps these operations into a set of weiyun.* MCP tools so higher-level skills can manage cloud drive files through structured requests.

How It Works

The skill exposes 14 tools for file management, including weiyun.list, weiyun.search, weiyun.download, weiyun.upload, weiyun.delete, weiyun.rename_file, weiyun.rename_dir, weiyun.create_dir, weiyun.move_file, weiyun.move_dir, and weiyun.gen_share_link. A typical flow is:
- Use weiyun.list first to get directory entries and the top-level pdir_key;
- Locate files with weiyun.search or weiyun.list_by_category;
- For downloads, fetch file_id and pdir_key, then call weiyun.download;
- For uploads, use the two-phase protocol, preferably with upload_to_weiyun.py for block_sha_list, chunked SHA1, and 50000 retries;
- Generate share links with weiyun.gen_share_link, which are intended to be opened in a browser.
Requests must include qua and version headers, and authentication is supplied via WyHeader: mcp_token=. The skill also includes check_skill_update for version checks.

Boundaries

This skill is scoped to Tencent Drive files only. It does not create or edit Tencent Docs, push files directly to WeChat/QQ, or support other cloud drives such as Baidu Netdisk or OneDrive. Upload requires Python; listing, downloading, sharing, deleting, renaming, moving, and searching generally do not. Directory deletion requires dir_name and should be reconfirmed by the user. Search results usually do not return pdir_key, so later operations may need to call weiyun.list again. Error codes such as 117402, 117407, 1192, and 50000 should be handled as token, authorization, directory-name, and service-retry issues respectively.
