When you pass a Google Drive /file/d/<id>/view URL to curl or aria2c, you download an HTML viewer shell instead of the file, and large files stop at Google's virus-scan confirmation page. On 2026-10-20 we benchmarked Share Link Resolver (MCP reference at https://sharelink.openkrill.app/mcp) on the public CelebA identity mapping file against gdown, WonderPlugin's converter and gdocs2direct. In 2,260 ms, resolve_share_link returned the exact file name (identity_CelebA.txt), byte size (3,424,458 bytes), direct drive.usercontent.google.com URL with confirm=t, and ready-to-run curl, aria2c and Aria2 JSON-RPC hand-offs.
13 supported providers across cloud drives and social links
Calling list_share_providers on https://sharelink.openkrill.app/mcp returns the 13 supported providers split into two categories:
- Google Drive (
google_drive,kind: "drive") acrossdrive.google.com,drive.usercontent.google.comanddocs.google.com. Public files get a directdrive.usercontent.google.com/download?id=<id>&export=download&confirm=tURL; public folders list one level viaembeddedfolderview; Google Docs, Sheets and Slides export as.docx,.xlsxand.pptx. - Baidu Netdisk (百度网盘,
baidu,kind: "drive") acrosspan.baidu.comandyun.baidu.com. Verifies optional 4-character extraction codes (?pwd=abcdor thepasswordargument) againstpan.baidu.com/share/verifyand lists the shared files and byte counts via/share/list(auth_need: "provider_sign_in"for downloading the bytes). - 11 social post canonicalizers (
kind: "social"): YouTube (youtube), X / Twitter (x), Reddit (reddit), TikTok (tiktok), Pinterest (pinterest), Instagram (instagram), Threads (threads), Facebook (facebook), LinkedIn (linkedin), Telegram (telegram) and Bilibili (bilibili). For these providers, the tool strips tracking parameters, expands shortener hosts and returns the clean canonical post URL withdownload: "none".
Step 1: Resolve a Google Drive file link and compare 3 rivals
We ran the same public Google Drive file link (https://drive.google.com/file/d/1_ee_0u7vcNLOfNLegJRHmolfH5ICW-XS/view) through Share Link Resolver and three rivals on 2026-10-20:
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "resolve_share_link",
"arguments": {
"url": "https://drive.google.com/file/d/1_ee_0u7vcNLOfNLegJRHmolfH5ICW-XS/view"
}
}
}The response in 2,260 ms includes the file metadata and three download hand-offs:
{
"status": "ok",
"provider": "google_drive",
"title": "identity_CelebA.txt",
"download": "direct",
"files": [
{
"name": "identity_CelebA.txt",
"is_folder": false,
"size_bytes": 3424458,
"open_url": "https://drive.google.com/file/d/1_ee_0u7vcNLOfNLegJRHmolfH5ICW-XS/view",
"direct_url": "https://drive.usercontent.google.com/download?id=1_ee_0u7vcNLOfNLegJRHmolfH5ICW-XS&export=download&confirm=t",
"handoff": {
"curl": "curl -L --fail -o 'identity_CelebA.txt' 'https://drive.usercontent.google.com/download?id=1_ee_0u7vcNLOfNLegJRHmolfH5ICW-XS&export=download&confirm=t'",
"aria2c": "aria2c -x 4 -s 4 -o 'identity_CelebA.txt' 'https://drive.usercontent.google.com/download?id=1_ee_0u7vcNLOfNLegJRHmolfH5ICW-XS&export=download&confirm=t'",
"aria2_rpc": {
"jsonrpc": "2.0",
"id": "openkrill-sharelink",
"method": "aria2.addUri",
"params": [
["https://drive.usercontent.google.com/download?id=1_ee_0u7vcNLOfNLegJRHmolfH5ICW-XS&export=download&confirm=t"],
{ "out": "identity_CelebA.txt" }
]
}
}
}
]
}Here is how Share Link Resolver compared against the three rivals on the same link:
| Tool | Wall time | Score | File name and size before download | Direct URL and CLI hand-off |
|---|---|---|---|---|
Share Link Resolver (resolve_share_link) |
2,260 ms | 9.6 / 10 | identity_CelebA.txt, 3,424,458 bytes |
drive.usercontent.google.com/download?...&confirm=t plus ready curl, aria2c and aria2.addUri JSON-RPC |
gdown CLI (uvx gdown <url> --json) |
3,866 ms | 8.2 / 10 | identity_CelebA.txt; no byte count without downloading |
Streams the file or writes drive.google.com/uc?id=... in --json; no aria2c or RPC hand-off |
| WonderPlugin Google Drive Converter | 2,615 ms | 7.6 / 10 | None (string regex only) | Rejected the plain /view URL until ?usp=sharing was appended; outputs drive.google.com/uc?export=download&id=... |
gdocs2direct (GitHub Pages widget) |
not run | not run | None | Client-side browser form only; no HTTP API or CLI mode |
Step 2: Strip tracking parameters and normalize social links
Pass any shared social URL to resolve_share_link to strip tracking query parameters and canonicalize legacy domains such as twitter.com:
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "resolve_share_link",
"arguments": {
"url": "https://twitter.com/OpenAI/status/1895186539732943114?s=20&utm_source=share"
}
}
}The tool returns provider: "x", canonical_url: "https://x.com/OpenAI/status/1895186539732943114" and download: "none".

Frequently asked questions
- How do I turn a Google Drive share link into a direct download URL for curl or aria2c?
- Paste the Google Drive link into tools.openkrill.app/sharelink or call resolve_share_link on https://sharelink.openkrill.app/mcp. For a public file, the tool returns the drive.usercontent.google.com/download URL with export=download&confirm=t alongside the file name, size in bytes, and ready curl -L, aria2c -x 4 -s 4 and aria2.addUri JSON-RPC payloads.
- How can I list the files inside a public Baidu Netdisk share link?
- Call resolve_share_link on https://sharelink.openkrill.app/mcp with the pan.baidu.com or yun.baidu.com share URL and pass the 4-character extraction code either in ?pwd=code on the URL or in the password argument. The resolver calls pan.baidu.com/share/verify and /share/list to return the file names, paths, byte sizes and modification timestamps.
- What is the clean canonical URL for a shared X, TikTok, or Instagram link without tracking parameters?
- Call resolve_share_link with a link from any of the 11 supported social platforms (YouTube, X, Reddit, TikTok, Pinterest, Instagram, Threads, Facebook, LinkedIn, Telegram or Bilibili). It strips tracking query parameters such as utm_source, s, si and igshid, expands short links like youtu.be or redd.it, and returns the canonical post URL.
- Does Share Link Resolver bypass private permissions or download social videos?
- No. It only resolves Google Drive and Baidu Netdisk links that the owner shared publicly, and for social links it returns only the clean canonical post URL (download: "none").
