概覽

AI 產生的概覽

託管的 Trestle 伺服器，讓助理驗證電話號碼，並檢查美國號碼的 TCPA 訴訟風險。

可以做什麼
  • 驗證電話號碼，回傳是否有效、國家、電信業者、線路類型、是否預付及 0-100 活躍度分數
  • 檢查美國號碼的 TCPA 訴訟風險（付費附加項目）
  • 查看當月用量與免費額度
  • 提出功能需求、升級至 Pro 或 Pro+、取消 Pro 訂閱
適用情境
適合在撥打電話前篩選潛在客戶或聯絡人名單：確認號碼有效且較可能接通，或在聯繫前篩查美國號碼的 TCPA 訴訟風險。
執行需求
遠端 MCP 端點，無需本機安裝。透過 OAuth 登入，首次連線時需提供 Trestle 入口網站的 Trestle API 金鑰，伺服器會依使用者儲存。需要 Trestle 帳號。免費方案每月 50 次工具呼叫。
安裝前請注意
TCPA 訴訟檢查為付費附加項目，僅在 Trestle 帳號中啟用後才能使用。付費方案會產生費用，升級會回傳 Stripe 結帳連結；取消後服務持續到付費週期結束，當期不退費。送出的號碼會傳送給 Trestle 查詢。請勿在用戶端設定中填入 API 金鑰或 Authorization 標頭。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Trestle MCP by usefulapi，將其新增到工作區。
  2. 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.usefulapi%2Ftrestle/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

Trestle MCP by usefulapi

Use your Trestle account from Claude, Cursor, or any MCP client. Validate phone numbers and check US numbers for TCPA litigator risk. Hosted, no local install: connect with your own credentials.

Live endpoint: https://trestle.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://trestle.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http trestle https://trestle.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "trestle": {      "url": "https://trestle.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Trestle credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/trestle/

On first connect you provide a Trestle API key (copy it from the Trestle portal at portal.trestleiq.com). The server validates it and stores it per user. No keys go in config files.

trestle_validate_phone

Validate a phone number

Check a phone number with Trestle Phone Validation. Returns whether it is valid, its country and carrier, its line type (Mobile, Landline, FixedVOIP, NonFixedVOIP, TollFree and so on), whether it is prepaid, and a 0-100 activity score (70 or above: likely connected; 30 or below: likely disconnected or unanswered). Does not return the owner's name. Use only for identity or lead verification, or caller routing. Never use the result for credit, insurance, employment, housing or benefits decisions (FCRA), or for marketing. Trestle Phone Validation API: GET /3.0/phone_intel.

trestle_check_tcpa_litigator

Check a US number for TCPA litigator risk

Validate a US phone number and run Trestle's TCPA litigator check. Returns add_ons.litigator_checks['phone.is_litigator_risk']: true when the subscriber is a known TCPA litigator, null when the check could not finish. US numbers only. The check is a paid add-on and works only when it is enabled on the API key; otherwise add_ons is missing from the reply. Use it to verify leads before you call or text them. Use only for identity or lead verification, or caller routing. Never use the result for credit, insurance, employment, housing or benefits decisions (FCRA), or for marketing. Trestle Phone Validation API: GET /3.0/phone_intel with add_ons=litigator_checks.
