dev.toolpin由 toolpin.dev 發布官方發布者v0.1.0更新於 Oct 25, 2026
Check whether an MCP server answers, what its tools claim, and whether that claim has changed.
一個遠端 MCP 伺服器，用來查詢其他 MCP 伺服器：可達性、所宣告的工具定義、雜湊值以及記錄到的變更。
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/dev.toolpin%2Ftoolpin/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。

}An MCP server that answers questions about other MCP servers: whether one answered when we last probed it, what its tools claimed to do, and whether that claim has changed since.
Useful when an agent is choosing which server to depend on, and useful in the moment something breaks and you want to know whether the tools moved under you.
https://toolpin.dev/mcp Streamable HTTP, stateless, no sign-up.
Full parameters and response shapes: https://toolpin.dev/api, or the machine-readable schema at https://toolpin.dev/openapi.json.
No key needed to read. Add one as an Authorization: Bearer header to raise the
limit, and to use watch_server, which acts on your account.
The limit counts distinct servers, not requests. Asking about the same servers all day costs one against the limit each, however often you ask, so watching your own dependencies never runs out. Never put a key in a URL.
No score, no grade, no rating, no safety judgment. Tool descriptions and annotations are reproduced exactly as the server published them: they are claims by that server's author, not anything Toolpin verified. A tool whose annotations say it only reads may do anything at all.
What Toolpin can tell you is whether the claim changed, because it hashes the fields the MCP specification defines and compares them daily. That is the whole product.
Methodology: https://toolpin.dev/methodology
Documentation and the published registry manifest. The service itself is closed source. Tool-definition changes are recorded in CHANGELOG.md, which is the same thing Toolpin watches for on everyone else.

Find MCP servers in the public registry by name or title. Returns the canonical name, description, and whether the server answered our last probe. Use this to turn a rough idea of a server into the exact name the other tools need.
limitquery必填Everything Toolpin has observed about one MCP server: reachability of each remote endpoint and when each was last checked and last verified, repository activity, the current tool-definition hash, and how many changes it has recorded in the last 90 days. The reply includes the catalog-wide drift rate so that count can be read against a baseline.
name必填The tool definitions one MCP server advertised when Toolpin last read them, each with a SHA-256 hash of the fields the MCP specification defines. Use this to see what a server's tools claim to do without connecting to it, or to compare a hash you pinned earlier.
name必填Changes Toolpin recorded for one MCP server: tool definitions changing, and endpoints going down or coming back. Each change says which tools moved and which of their fields differed, with the hash before and after. Includes the catalog-wide drift rate for comparison.
daysname必填The current MCP specification revision, which of its proposals Toolpin checks for, and how much of the catalog has migrated. Use this to find out what the current revision is and how unusual it is to still be on an older one.
無需輸入參數。
Start monitoring an MCP server on the caller's Toolpin account, so they are emailed when it changes or stops answering. Needs an API key. Says so plainly if the account is already at its plan limit rather than failing.
