SELL TO STATE.
立即开始
基于 HTTP 的 MCP · 26 个工具

你的智能体可自主使用的采购数据。

Point any MCP-capable client — Claude Desktop, Claude Code, Cursor, or your own agent — at our streamable-HTTP endpoint. It can search government tenders and contract awards from official sources, drill into buyers and suppliers, keep lists, and even self-register and pay for access with no human in the loop.

# 端点

https://staging-app.selltostate.com/api/mcp

# 列出工具（开放，无需认证）

curl -s https://staging-app.selltostate.com/api/mcp \
  -H "content-type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,
       "method":"tools/list"}'

tools/list is open; tools/call resolves your credential and 402s if un-entitled.

Add it to your client.

Clients with a browser sign you in with OAuth. Other clients send an API key from your account. The server is in the official MCP Registry as com.selltostate/mcp.

Claude

Customize, then Connectors. Select + Add, then Add custom connector. Paste the URL and select Connect.

Claude Code

Add the server, then run /mcp and choose Authenticate.

Gemini CLI

Install the extension. Gemini CLI opens your browser to sign in.

Step by step →

Cursor and other clients

Add the server to mcp.json with your API key in the x-api-key header.

{
  "mcpServers": {
    "selltostate": {
      "url": "https://staging-app.selltostate.com/api/mcp",
      "headers": { "x-api-key": "sts_..." }
    }
  }
}

连接流程。

  1. 1

    发现

    符合规范的客户端读取 /.well-known/oauth-protected-resource（RFC 9728）与 /.well-known/oauth-authorization-server（RFC 8414），以了解资源、颁发者与作用域。

  2. 2

    注册

    在没有预共享凭据的情况下，客户端通过 RFC 7591 DCR（POST /api/oidc/register）自助注册，获得一个数据作用域为零的 client_id 以及一个 payment_link。

  3. 3

    Authenticate

    Clients with a browser (Claude, ChatGPT, Cursor) run the OAuth 2.1 authorization-code flow with PKCE, and you sign in with your Sell to State account. An agent without a browser presents the issued client as Authorization: Bearer client:<client_id> on every tools/call.

  4. 4

    订阅

    在客户端的主体获得权限之前，每次 tools/call 都会返回与 REST 相同的 402 响应体 —— 一个面向人的 payment_link 和智能体原生的 machine_payment 能力。智能体调用 pay，在会话外（off-session）完成扣款，其下一次调用即返回数据。

26 个工具，与 REST 对等。

Every tool mirrors a REST endpoint 1:1. Owner-scoped list / saved-search tools require a user API key; an OIDC client token gets a requires_user_key result. Full schemas in the reference.

whoami data:read 身份 + 权限 + 作用域（不受限 —— 消费前先验证）。
search data:read 对单一作用域进行分面检索：tenders | buyers | suppliers | sectors。
search_awards data:read 授标浏览器（q、机构、供应商、类别、年份、金额区间）。
get_buyer data:read 采购方详情（get_buyer_detail 为保留别名）。
get_supplier_detail data:read 供应商详情，含主要采购方 + 行业分布。
get_sector / get_tender data:read 行业概览 · 单份授标 + 相关授标。
list_buyers / list_suppliers / list_sectors data:read 前 N 名机构、供应商及行业分类法。
get_lists / create_list / add_to_list … data:read 已保存授标列表的 CRUD —— 需要用户 API 密钥。
get_saved_searches / save_search … data:read 已保存检索的 CRUD —— 需要用户 API 密钥。
export data:export 将筛选后的授标集导出为 CSV。
pay billing:pay 使用 Stripe 令牌自主付款以解锁访问 —— 无需结账页面。

调用工具。

curl -s https://staging-app.selltostate.com/api/mcp \
  -H "Authorization: Bearer client:c_abc123" \
  -H "content-type: application/json" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call",
       "params":{"name":"search",
                 "arguments":{"scope":"tenders","q":"cloud","year_min":2024}}}'

连接后，直接提问

  • → “在 Sell to State 中检索 2024 年的网络安全授标，并总结排名前 5 的供应商。”
  • → “拉取教育部今年做出的每一份授标，并将其导出为 CSV。”
  • → “对相关机构使用 get_buyer —— 新加坡从谁那里采购建筑服务？”

连接你的智能体。
