概览

AI 生成的概览

将助手连接到 inv.bg 开票账户,可读取发票、客户、商品、付款与银行数据,并创建客户、商品和发票。

可以做什么
  • 读取账户、公司信息、单据类型、号码组、付款方式和免增值税原因
  • 列出并查看发票、客户与客户联系人、商品目录及计量单位
  • 查看付款、银行账户、用于对账的银行流水、钱箱和汇率
  • 创建和更新客户、创建商品,并创建草稿或已开具的发票
  • 将发票通过电子邮件发送给收件人,并为发票登记付款
适用场景
适合在 inv.bg 中管理开票、希望助手直接回答未付或应收发票问题、查询客户与付款,或在不打开应用的情况下起草发票和登记付款的场景。
运行要求
通过 URL 连接的远程 MCP 端点,无需本地安装。登录使用 OAuth,首次连接时需输入 inv.bg API 令牌(位于设置 > 关于公司 > API 访问),按用户存储。免费方案每月 50 次工具调用,付费方案可提高上限。
安装前请注意
写入类工具会改动真实账务数据:创建已开具发票会占用下一个法定编号,且无法通过该服务器撤销;发送发票邮件会立即发出且无法撤回。登记付款时即使分配失败,付款仍会被记录。inv.bg API 令牌属于凭据。付费方案需付费,通过结账链接订阅,取消后当期不退款。

  1. 打开 控制台中的 inv.bg MCP by usefulapi,将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

README

inv.bg MCP by usefulapi

Use inv.bg from Claude, Cursor, or any MCP client — work with your invoices, clients, items, payments and bank transactions. Hosted, no local install: connect with your own inv.bg credentials.

Live endpoint: https://inv-bg.usefulapi.io/mcp · Homepage: https://usefulapi.io/inv-bg

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://inv-bg.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http inv-bg https://inv-bg.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": {    "inv-bg": {      "url": "https://inv-bg.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 inv.bg credentials.

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

On first connect you'll enter your inv.bg API token (Settings > About the Company > API access). It is validated, stored per-user, and scoped to you — no keys in config files.
