Production deployment

The repository includes:

• GitHub Actions CI workflow: .github/workflows/ci.yml
• GitHub Actions deployment workflow for self-hosted runner label macmini: .github/workflows/deploy-macmini.yml
• launchd template: deploy/launchd/com.ctk03272.mcp-korean-stock.plist

Production runtime expects:

• MCP_TRANSPORT=http
• host-local .env
• deployment root under /Users/<runner-user>/services/mcp-korean-stock
• launchd starts the service through deploy/run_server.sh, which loads shared/.env before executing Python

Notes

• Intraday 10-minute data uses an unofficial Naver endpoint and may be delayed or subject to upstream schema changes.
• Profile fields are limited to what FinanceDataReader exposes in listing datasets.
