已驗證Streamable HTTP可網頁執行雲端與基礎設施開發者工具

概覽

AI 產生的概覽

唯讀 MCP 伺服器，依實際運算成本排序 GitHub 組織的 Actions 工作流程與儲存庫，並提供修正 diff 建議。

可以做什麼
  • 依實際運算成本排序組織內的 GitHub Actions 工作流程與儲存庫
  • 取得可直接貼上的修正 diff，例如補上快取或 timeout-minutes，並以實際執行時間驗證
  • 每次呼叫可免費取得成本排名與一項已驗證的修正 diff
適用情境
當 GitHub Actions 的 CI 花費偏高或不清楚來源時，用來找出是哪個工作流程或儲存庫推高帳單，並取得具體的 workflow 修改建議，不必另開儀表板。
執行需求
遠端端點 spendtron.com，使用 streamable HTTP。需在 Authorization 標頭提供 bearer 權杖（spendtron API 金鑰，安裝 GitHub App 後僅顯示一次），並連接具備 Actions、Contents、Metadata 唯讀權限的 GitHub App。
安裝前請注意
API 金鑰是放在 Authorization 標頭中的機密。成本排名與一項修正 diff 免費，解鎖完整修正清單需透過 Stripe 一次性支付 39 美元。服務會透過 GitHub App 讀取組織的 Actions 執行紀錄與儲存庫內容，這些資料會傳送給第三方。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 spendtron，將其新增到工作區。
  2. 連接 Authorization token 憑證。它們會被私密儲存，絕不會在公開頁面上展示。
  3. 為需要使用其工具的對話啟用該服務。

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。

交給代理程式安裝

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.github.swantron%2Fspendtron/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。

README

spendtron

A read-only tool that finds which GitHub Actions workflow is eating your CI bill, ranks workflows and repos by real compute cost, and suggests pasteable fix diffs (missing cache, missing timeout-minutes) confirmed against real run timing — not estimates.

Delivered as an MCP server — call check_actions_cost from Claude, ChatGPT, or any MCP-compatible client, no dashboard required. Auth is a GitHub App (read-only: Actions + Contents + Metadata) plus a spendtron API key, passed as a bearer token. The cost ranking and one confirmed fix diff are free on every call. Unlocking the full fix list is a one-time $39 payment via Stripe — not a subscription.

The underlying audit logic started as ~/code/ci-audit/actions-teardown.sh (bash + gh api) — lib/auditActions.js is the same algorithm, ported to run per-installation against many customers' orgs instead of one local gh-authenticated user.

Status

Real product, not a waitlist — see HANDOFF.md/FINDINGS.md/CARRD.md in ~/code/ci-audit for the history of how this got here (an earlier waitlist-and-post-to-Reddit attempt correctly got abandoned; the audit logic itself was always real).

The GitHub App must be public (GitHub → spendtron-app → Advanced → Make this GitHub App public) so anyone can hit Connect GitHub. That toggle lives in the GitHub UI, not this repo.

Setup

  1. Copy .env.example to .env.local (or set these in Cloud Run's Secret Manager for prod).
  2. Create a GitHub App at github.com/settings/apps/new — slug spendtron-app, permissions: Actions: Read-only, Contents: Read-only, Metadata: Read-only. Callback URL: <your deployed host>/github/callback. Make the App public before sending customers to /github/install.
  3. Create a Neon Postgres database, run db/schema.sql against it.
  4. Create a one-time Stripe Price (not recurring) for the fix-diff unlock; put its ID in STRIPE_UNLOCK_PRICE_ID. Point a Stripe webhook at /stripe/webhook for checkout.session.completed. (STRIPE_PRICE_ID and the Customer Portal are legacy from an earlier $99/mo model — no longer wired into any live checkout flow.)
  5. Map both spendtron.com and www.spendtron.com to the Cloud Run service (www should CNAME to ghs.googlehosted.com at Squarespace). The app 301s www → apex.
  6. Privacy / terms for Stripe: https://spendtron.com/privacy and https://spendtron.com/terms.
  7. npm install && npm start.

Test

npm test — covers the cost-math port (must match actions-teardown.sh's bash/awk exactly) and API-key auth, against a mocked GitHub client (no live credentials needed for these).
