FAQ from TossInvest OpenAPI MCP

What happens if I start the server without credentials?

The server starts but reports missing configuration via auth_status instead of crashing. No tools fail unexpectedly.

Are my API credentials exposed to model providers?

No. OAuth tokens remain in memory only, and all secrets, bearer tokens, and account identifiers are redacted from tool output and errors.

Can I trade using this server?

Trading is disabled by default. Order tools default to dryRun=true. Real order create, modify, or cancel operations require explicit environment gates, confirmation text, and maximum order limits to be set.

What data can I access with read-only tools?

You can inspect account information, market data, holdings, orderbooks, candles, and order history.

What transport does the server use?

The server uses local stdio transport (no HTTP endpoints exposed).
