Golddigger MCP Server

B2B Lead Intelligence API — search, enrich & score 10M+ global companies from any MCP-compatible client.

MCP Server License: MIT Data Sovereignty

What is this?

A Model Context Protocol (MCP) server that wraps the Golddigger API — giving AI assistants (Claude, Cline, Cursor, etc.) the ability to search, enrich, and score B2B leads in real time.

4 tools exposed:

Data Sovereignty

  • ✅ Report generation: 100% local (matplotlib + python-docx). No data leaves the user's machine.

  • ✅ Scoring: Pure local computation — six-dimension model runs on-device.

  • ⚠️ Search: Calls Golddigger API. Customer provides their own API key — costs borne by customer.

Installation

git clone https://github.com/SassumiX/golddigger-mcp.git
cd golddigger-mcp
pip install -r requirements.txt

Configuration

# Set your Golddigger API key (customer provides their own)
export GOLDDIGGER_API_KEY="gd_your_key_here"
export GOLDDIGGER_HOST="https://golddigger.gold"   # 可选
export GOLDDIGGER_DAILY_BUDGET=20     # 可选:本地软预算,默认 20
export GOLDDIGGER_QUOTA_RESERVE=2     # 可选:剩余低于此值不再自动搜

Token billing: The search_leads tool uses the customer's API key. Report generation is free (no external API calls).

Pricing

Plan

每日配额

Free

20 次/天(2026-10-06 由 GET /api/quota 实测得出,00:00 UTC 重置)

Paid

见 https://golddigger.gold

⚠️ 别信任何写死的配额数字,以 check_quota 的实时返回为准。 Get your key at https://golddigger.gold

search 每天只有 20 次,draft_outreach 不限次数、不耗配额 —— 因为找人的成本高, 开口的成本为零。所以工作流必须是:

check_quota → search_leads(dry_run) → search_leads → 对每条 lead 跑 draft_outreach → 进 outreach_queue.csv → 按 D0/D3/D7/D14 跟进

draft_outreach 会按公司描述自动识别角色(进口商 / 地产开发商 / 酒店 / 民宿)并切换话术, 支持 email / linkedin / whatsapp / wechat 与中英双语,队列按 company+channel 去重。

r = golddigger.draft_outreach(
    lead={"company": "Bin Harkil Group", "contact": "Procurement",
          "country": "SA", "industry": "real estate developer"},
    my_profile="smart lock factory, OEM/ODM, CE, MOQ 200, 7-day samples",
    channel="email", language="en",
)
# r["subject"], r["body"], r["followup_plan"], r["quota_cost"] == 0

已知问题 / 端点实测(2026-10-06)

端点

状态

GET /api/health

✅

GET /api/quota

✅ 真实配额端点(旧代码用的 /api/tenants/me 从未上线)

GET /api/leads

✅

POST /api/search

⚠️ 当前 500,站点侧故障,重试无用(5xx 不扣配额)

GET /api/leads/search

❌ 从未部署(旧 search_leads 打的就是这个,恒 404)

配额纪律(Agent 必读)

  1. 批量挖客前先调 check_quota,别让 Agent 自由发挥地循环搜索。

  2. search_leads(dry_run=True) 可以预演请求,不烧配额 —— 先批量预演,再挑着真跑。

  3. 本地预算账本写在 ~/.golddigger/search_budget.json,默认上限 20/天,按天重置。

  4. 剩余 ≤ 2 次(GOLDDIGGER_QUOTA_RESERVE)时 search_leads 直接拒绝发起,留额度给人工决策。

  5. 优先级:采购角色词 > 产品细分词 > 泛需求词。泛需求词最费额度、命中率最低。
