EasyPost + ChatGPT
让你的 AI 用 EasyPost 发货：验证地址，比较你的承运商的实时运费，购买、转换、投保和退款运单标签，追踪包裹，准备海关申报单，并创建 scan form。测试密钥免费。
前提条件
完整的设置说明已内置在连接器中 (在 store 中选择连接器时可见)。所需环境变量:
EASYPOST_API_KEY
步骤 1 — 获取凭证
- 在
https://app.easypost.com/signup注册一个免费的 EasyPost 账号。在显示 API 密钥之前，EasyPost 会要求你设置钱包和发货地址；新账号可能还需要先填写一份包含公司信息的简短安全审核。EasyPost 通过审核后，密钥就会显示出来。 - 打开 API 密钥页面
https://app.easypost.com/account/settings?tab=api-keys（Account settings → API keys）。复制 Test 密钥（免费，标签无效）或 Production 密钥（购买真实标签）。 - 把它粘贴到
EASYPOST_API_KEY并安装连接器。 - 运行
easypost_list_addresses检查密钥。新账号的列表可能为空。
测试还是正式：由密钥决定。使用测试密钥时，标签不收费且无效，追踪只接受 EasyPost 的测试单号 EZ1000000001 到 EZ7000000007，每个单号对应一种状态（尚未揽收、已签收、退回寄件人等）。列出已连接的承运商账户（easypost_list_carrier_accounts）需要正式密钥。
购买要花钱，所以会先确认：使用正式密钥时，easypost_buy_shipment 和 easypost_insure_shipment 会立即从 EasyPost 钱包扣款。购买前，AI 会说明承运商、服务、价格和双方地址，并等待你确认。购买后追加的保险费用为投保金额的 1%，最低 1 USD。easypost_refund_shipment 会作废未使用的标签，作废后不能再使用；退款需要几天到几周（USPS 标签须在 30 天内申请，UPS 和 FedEx 在 90 天内）。
发货流程：easypost_create_shipment 接收收件人、发货地址和包裹，返回你的承运商的实时运费，附带价格和送达天数。你和 AI 一起选定一个运费后，AI 用 easypost_buy_shipment 购买标签，并获得标签链接（PNG，或通过 easypost_convert_label 获取 PDF 和 ZPL）、追踪单号和公开的追踪页面。用 easypost_get_tracker 跟踪包裹，或用 easypost_create_tracker 开始追踪任意单号，包括在别处购买的标签。AI 还可以验证地址，并创建 scan form，让承运商揽收时只扫描一张单据。
单位和国际发货：重量以盎司为单位，尺寸以英寸为单位（1 kg 为 35.27 oz，1 cm 为 0.394 in），未指定币种时金额为 USD。国际发货时，AI 会先创建报关物品和海关申报单，再把申报单附加到发货上。
常见错误：401 UNAUTHORIZED 或 403 APIKEY.INACTIVE：密钥缺失、错误或已停用。403 MODE.UNAUTHORIZED：该调用需要正式密钥。402 PAYMENT_REQUIRED：钱包中没有资金。ADDRESS.VERIFY.FAILURE、SHIPMENT.POSTAGE.FAILURE 或 SHIPMENT.CUSTOMS_INFO.REQUIRED 等 422 错误会指出地址、购买或缺少海关数据的问题。429：请求过多，请稍候重试。
该连接器不处理上门揽收、订单、退货、Webhook、用户和 API 密钥、报表，也不负责连接承运商账户。
步骤 2 — 安装 adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
步骤 3 — 在 ChatGPT 中添加连接器
你的服务器 URL： 在 AnythingMCP 中打开 MCP Servers → 此连接器所在的服务器，复制它的 URL（
https://cloud.anythingmcp.com/mcp/…）。本指南中出现YOUR_SERVER_ID的地方都用它替换。
ChatGPT 在网页版的 Plugins 页面把 MCP 服务器添加为插件，仅付费套餐可用，不再需要开发者模式。在 Business 工作区中只有管理员和所有者可以添加；在 Enterprise 和 Edu 中，管理员可以授予 Create plugins with MCPs 权限。
- 前往 chatgpt.com/plugins，点击 +，然后选择 Add custom MCP server。
- 填写名称，例如 Name:
EasyPost。 - 在 Connection 下的 Server URL 中填入
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID，Authentication 保持为 OAuth。 - 选择 I understand and want to continue，然后点击 Create as a plugin。ChatGPT 提示时，登录 AnythingMCP 并允许访问。
- 在个人插件中安装这个新插件，然后在对话中输入 @ 并选择它。

ChatGPT 免费套餐能用自定义 MCP 服务器吗? OpenAI 只为付费套餐提供自定义 MCP 服务器的说明，Free 套餐不在其列。
