Business phone and SMS for teams: calls, texts, transcripts, contacts and call flows.

已验证Streamable HTTP可网页运行效率与工作流沟通与协作

概览

AI 生成的概览

Relay 的远程 MCP 服务器，面向团队商务电话与短信，让助手查看通话、短信和转录，管理联系人，发送短信并起草呼叫流程。

可以做什么
  • 列出团队与电话号码、最近的呼叫和短信，并读取带 AI 摘要和待办事项的通话转录
  • 按名字、姓氏或公司搜索联系人，新增或更新团队通讯录中的联系人，并列出组织成员
  • 以团队号码发送短信
  • 列出并读取呼叫流程、查看流程结构说明、从模板创建流程、保存或丢弃草稿，并在不写入的情况下测试流程图
适用场景
适合团队通过 Relay 处理电话和短信的场景：让助手汇总近期通话、查询或更新联系人、发送短信，或在人工上线前起草并检查呼叫路由流程。
运行要求
远程 streamable HTTP 端点 api.yesrelay.com，服务器端无需安装。需要 Relay 账户，并在应用的管理、集成与 API 中创建 API 密钥，以 Authorization Bearer 令牌方式发送。发送短信需付费套餐，流程工具需 Business 或 Scale 套餐。
安装前请注意
API 密钥只显示一次，撤销前同时授予 MCP 和 REST 访问权限。发送短信是真实、计费且不可撤回的操作，并受退订、每日上限、预算上限和发送暂停等检查限制。创建和更新联系人会修改团队数据。没有工具能发布流程，草稿需由人工在应用中上线。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Relay，将其添加到工作区。
  2. 连接 所需的 凭据。它们会被私密存储，绝不会在公开页面上展示。
  3. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.yesrelay%2Frelay/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

其他 MCP 客户端

把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

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.
