概覽

AI 產生的概覽

Relay 的遠端 MCP 伺服器，面向團隊商務電話與簡訊，讓助理查看通話、簡訊與逐字稿，管理聯絡人，發送簡訊並草擬來電流程。

可以做什麼
  • 列出團隊與電話號碼、最近的來電和簡訊，並讀取含 AI 摘要與待辦事項的通話逐字稿
  • 依名字、姓氏或公司搜尋聯絡人，新增或更新團隊通訊錄中的聯絡人，並列出組織成員
  • 以團隊號碼發送簡訊
  • 列出並讀取來電流程、查看流程結構說明、從範本建立流程、儲存或捨棄草稿，並在不寫入的情況下測試流程圖
適用情境
適合團隊以 Relay 處理電話與簡訊的情境：讓助理彙整近期通話、查詢或更新聯絡人、發送簡訊，或在人工上線前草擬並檢查來電轉接流程。
執行需求
遠端 streamable HTTP 端點 api.yesrelay.com，伺服器端無需安裝。需要 Relay 帳號，並在應用程式的管理、整合與 API 中建立 API 金鑰，以 Authorization Bearer 權杖方式送出。發送簡訊需付費方案，流程工具需 Business 或 Scale 方案。
安裝前請注意
API 金鑰只顯示一次，撤銷前同時授予 MCP 與 REST 存取權。發送簡訊是真實、計費且不可撤回的操作，並受退訂、每日上限、預算上限與發送暫停等檢查限制。建立與更新聯絡人會變更團隊資料。沒有工具能發布流程，草稿需由人工在應用程式中上線。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Relay，將其新增到工作區。
  2. 連接 所需的 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.yesrelay%2Frelay/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。

其他 MCP 客戶端

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。

README

Relay MCP server

Remote Model Context Protocol server for Relay, a business phone and SMS app for teams, built in Montreal.

It lets Claude, or any MCP client, work with your team's phone: list calls and texts, read call transcripts, search and update contacts, send an SMS from the team number, and draft call-routing flows.

Endpointhttps://api.yesrelay.com/api/mcp
TransportStreamable HTTP (spec 2025-06-18), stateless
AuthenticationAuthorization: Bearer <Relay API key>
Tools16
PlansEvery plan, free included
Documentationhttps://yesrelay.com/en/api-docs

This repository holds no server code: the server is hosted by Relay. Nothing to install on the server side.

Get an API key

  1. Create a free account at https://app.yesrelay.com.
  2. In the app, open Administration, then Integrations & API, and create a key.
  3. The key starts with rk_live_ and is shown once. Keep it in a secrets manager.

Revoking the key in the app cuts MCP and REST access at the same instant.

Connect a client

Claude Code

bash
claude mcp add --transport http relay https://api.yesrelay.com/api/mcp \  --header "Authorization: Bearer rk_live_..."

Claude Desktop

claude_desktop_config.json, through mcp-remote:

json
{  "mcpServers": {    "relay": {      "command": "npx",      "args": ["mcp-remote", "https://api.yesrelay.com/api/mcp",               "--header", "Authorization:${AUTH}"],      "env": { "AUTH": "Bearer rk_live_..." }    }  }}

Any other client

Point it at https://api.yesrelay.com/api/mcp with the Authorization header above.

Tools

Calls and messages

ToolWhat it does
relay_list_numbersLists the organization's teams and their phone numbers
relay_list_callsRecent calls of a team, newest first
relay_get_transcriptTranscript of a call, with the AI summary and action items
relay_list_messagesRecent texts of a team, newest first, filterable by contact
relay_send_smsSends a text from the team number. Real, billed and irreversible

Contacts and team

ToolWhat it does
relay_search_contactsSearches a team's address book by first name, last name or company
relay_create_contactAdds a contact to the team's address book
relay_update_contactReplaces the fields of an existing contact
relay_list_membersPeople in the organization and their identifiers

Flow (call routing, Business and Scale plans)

ToolWhat it does
relay_list_flowsLists the organization's call flows
relay_get_flowReads the live graph and the draft of a flow
relay_flow_schemaBlock types, expected fields and routing-engine rules
relay_create_flowCreates a number's flow from a template
relay_save_flow_draftReplaces the draft. Changes nothing callers hear
relay_check_flowTests a graph without writing anything
relay_discard_flow_draftThrows away the draft and returns to what is live

No tool publishes a flow. An agent can draft and check a call path; a person puts it live from the app.

Safeguards

A text sent through MCP goes through the same checks as a text sent from the app:

Refusal codeWhen
recipient_opted_outThe recipient replied STOP (or ARRET, UNSUBSCRIBE) to this team
daily_limit_reachedThe team's daily cap is reached (the customer's own limit, or the automatic one)
workspace_budget_reachedThe team's spending cap is reached
sending_suspendedOutbound sending is paused by the circuit breaker; receiving continues

What you can do also follows your plan: sending texts needs a paid plan, and the Flow tools need Business or Scale.

Limits

PlanRequests per minute per keyKeys
Free302
Paid1205

Each message in a JSON-RPC batch counts as one request.

Troubleshooting

The client shows a read error, or curl fails with error 56 ("chunk hex-length"). Some antivirus software that inspects HTTPS traffic corrupts MCP responses; we have seen it with Avast. The server answered correctly. Exclude api.yesrelay.com from your antivirus HTTPS scanning, then try again.

401 Invalid API key. The key is missing, revoked or expired. Create a new one in the app.
