快速启动（地方发展）
# 1. Install dependencies
npm install
# 2. Build TypeScript
npm run build
# 3. Run with mock APIs (no real API keys needed)
npm start
# 4. Test with MCP Inspector
npm run inspect______________________________________________________________________
部署到AWS EC2
# On EC2 — install Node.js 20
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y nodejs
# Clone/upload project
scp -i your-key.pem -r ./loan-verification-mcp-server ec2-user@YOUR_EC2_IP:~/
# Install and build
cd loan-verification-mcp-server
npm install
npm run build
# Run as HTTP server (for Claude API integration)
TRANSPORT=http PORT=3001 npm start
# Keep alive with PM2
npm install -g pm2
pm2 start "TRANSPORT=http PORT=3001 npm start" --name loan-mcp
pm2 save
pm2 startupNginx反向代理配置

连接到Claude（Claude_desktop_config.json）
对于 本地克劳德桌面 （标准版本）：
{
"mcpServers": {
"loan-verification": {
"command": "node",
"args": ["/path/to/loan-verification-mcp-server/dist/index.js"],
"env": {
"USE_MOCK_APIS": "true"

}
}
}______________________________________________________________________
切换到真实API
设置环境变量并设置 USE_MOCK_APIS=false:
export USE_MOCK_APIS=false
export PAN_API_KEY=your_nsdl_key
export GST_API_KEY=your_gst_key
export AADHAAR_API_KEY=your_uidai_key
export FRAUD_API_KEY=your_internal_key
export OCR_API_KEY=your_aws_textract_key
export DENTAL_API_KEY=your_dci_key
# Set real endpoints
export PAN_VERIFY_URL=https://your-pan-api.com/verify
export GST_VERIFY_URL=https://api.gst.gov.in/commonapi
export OCR_URL=https://your-aws-textract-wrapper.com______________________________________________________________________
克劳德对话示例
User: I have a new dental clinic loan application.
Case ID: LOAN-2024-001
Applicant: Dr. Rajesh Sharma, PAN: ABCDE1234F
Loan type: clinic_setup
Uploaded docs: PAN_CARD, AADHAAR, DENTAL_DEGREE_BDS, ITR, BANK_STATEMENT
Claude: [calls orchestrate_stage2_verification]
→ Gets execution plan with 7 steps
[calls doc_validate_document_set] → PASS: PROJECT_REPORT and LEASE_AGREEMENT missing
[asks user for missing docs]
[calls kyc_validate_pan + fraud_query_registry in parallel]
→ PAN: PASS | Fraud: PASS
[calls kyc_verify_aadhaar + credential_verify_dental]
→ Aadhaar: PASS | Credential: PASS (9 years practice)
[calls orchestrate_generate_verification_summary]
→ Risk score: 10/100 (LOW) | PROCEED TO STAGE 3______________________________________________________________________
