io.vpndetection由 vpndetection.io 發布官方發布者v6.2.6更新於 Nov 6, 2026
VPN, proxy, Tor, hosting and CDN detection for any IP address, from the VPNDetection API.
VPNDetection 可判斷 IP 位址是否屬於 VPN、代理、Tor、主機代管或 CDN，並提供資料庫目錄與授權狀態查詢。
Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。
把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。
閱讀 https://sourceweft.com/mcp/io.vpndetection%2Fmcp/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。把它新增到你客戶端的 mcpServers 設定中。 客戶端會在首次連接時完成 OAuth 登入。

}The official Model Context Protocol server for the VPNDetection API.
It gives an AI agent seven read-only tools for anonymity detection: whether an address belongs to a VPN, a residential, datacenter, mobile or public proxy, a Tor node, a privacy relay or web gateway, a hosting provider or a CDN, plus the database catalog and where your organization's license for each one stands.
We host it at https://mcp.vpndetection.io/mcp, and you sign in to it with your VPNDetection account. It also runs on your own machine from npm.
In claude.ai, the desktop app or Cowork, add https://mcp.vpndetection.io/mcp as a custom connector and choose Use Claude's published identity when asked. In Claude Code, install our plugin, which adds the server with skills:
Either way you sign in with your VPNDetection account, and Claude never sees your API key. The steps, the skills and how to disconnect: docs.vpndetection.io/integrations/claude.
In ChatGPT on the web, add https://mcp.vpndetection.io/mcp as a custom MCP server under Plugins and choose OAuth. In Codex, install our plugin, which adds the server with skills:
Either way you sign in with your VPNDetection account, and neither sees your API key. The steps: docs.vpndetection.io/integrations/chatgpt and docs.vpndetection.io/integrations/codex. On the OpenAI API, the Responses API's mcp tool takes the server as its server_url and your key as its authorization.
Point it at https://mcp.vpndetection.io/mcp. A client that supports MCP authorization signs in the same way. One that doesn't can send a key instead, as Authorization: Bearer your-key.
No API key needed to start. Without a key, a lookup answers ip and is_vpn, up to 1000 a day per source address. A free key adds Tor and relay detection, where the address is and the AS that announces it, and every paid plan answers every field.
Add this to your MCP client's config:
Requires Node.js 22 or newer.
A key unlocks the provider name, the classification databases and the proxy families. Put it in the environment:
VPNDETECTION_BASE_URL overrides the endpoint if you need to point somewhere else.
The database tools need a key with the db.download scope, which your organization's Default key has.
Every tool is read-only. There is deliberately no download tool: the databases run to several GB, which is not something an agent should pull into a conversation. Fetch them with the client libraries or the API instead.
There is deliberately no my_ip tool, although every client library has one. Over a hosted transport the address our edge observes belongs to whatever proxied the call - Claude's infrastructure, not the person asking - so the tool would answer confidently and wrongly for the only reading anyone would put on it. my_entitlement has no such problem and is the same answer from any transport, because it describes the credential rather than the connection. A test pins the tool's absence so it cannot be added back by accident.
Usage counts against the anniversary of the subscription, not the calendar month and not the billing period. A null hard_limit means we never stop serving; it is not a limit of zero.
Each lookup comes back with a coverage block beside it:
This matters more here than in a normal client library. A field missing from a result means your plan doesn't include it, never "we checked and found nothing" - and a model reading the result on its own will otherwise treat the absence as a negative answer. coverage states the difference explicitly so it can't.
There are official VPNDetection client libraries available for many languages including PHP, Python, Go, Java, Ruby, and many popular frameworks such as Django, Rails, and Laravel. See our GitHub at https://github.com/vpndetection-io for more.

Look up an IP address
Classify a single IPv4 or IPv6 address: whether it belongs to a VPN, a residential, datacenter, mobile or public proxy, a Tor node, a privacy relay or web gateway, a hosting provider or a CDN, with the provider name where we have one. Private and reserved addresses are answered locally, without calling the API. Always read `coverage.note` before concluding anything from a field that is not in the result.
ip必填Look up several IP addresses
Classify a list of addresses in one call, returning a map keyed by address so duplicates collapse and the order you passed them stops mattering. Pass the whole list rather than splitting it yourself: a long one is batched for you. Prefer this over repeated `lookup_ip` calls when you already have the list, for example when triaging a log file. An address that fails carries its error in place of a result rather than failing the batch. Always read `coverage.note` before concluding anything from a field that is not in the result.
ips必填Plan and usage for this key
What this API key is entitled to and how much of it has been used: the plan, the field tier that decides how much of a lookup answer comes back, the requests counted so far, the allowance, and when it resets. Use it to explain why a field is missing from a lookup, or before a large batch. Usage counts against the anniversary of the subscription rather than the calendar month, and can lag a few seconds behind. A null `hard_limit` means we never stop serving - it is NOT a limit of zero.

List databases
The database catalog as this API key's organization may see it, one entry per database FAMILY, with `standing` saying where their license stands: `licensed` if the family is theirs today, `expired` if the term has ended, `unlicensed` if it is published but has never been bought. Each entry has a `base` ID, which is what the license names, and a `versions` array whose `id` is what the other database tools take - pass `versions[].id` (`cdn_ip_v1`), never the `base` (`cdn_ip`). Ask again rather than holding on to this: it is answered per key and is not the same for everyone.

Describe a database
What is inside one database before you fetch it: the columns in each published format with their types, a few sample rows, the row count, the build date and the file sizes. Use this to answer questions about what a database contains without downloading it - the files reach several GB - and to budget a transfer before starting one.
dataset_id必填Get a database's checksums
The published digests for one database file, for verifying a copy you already hold or deciding whether a build has changed since you last fetched it. It is licensed like the download itself, so a database this key cannot download is refused here too. Looking up a checksum is not a download and does not appear in `list_downloads`.
format必填dataset_id必填List recent download attempts
This organization's own recent download attempts, newest first, REFUSALS INCLUDED - a denial carries the `outcome` and `http_status` that answer "it stopped working", which nothing else here can. Use it to explain a failing fetch, to confirm a transfer ran, or to check whether a request was theirs. This is a bounded WINDOW of at most 200 rows, so a database missing from the answer means it is not in this window - never that it was never downloaded.
