The server acts as a proxy for an external API. It utilizes robust JSON schema validation for all tool inputs, preventing common injection vulnerabilities. URL construction in the API client is safe, concatenating a fixed base URL with validated paths, mitigating SSRF risks. There are no direct usages of dangerous functions like `eval` or `child_process.exec` with user-controlled input in the main server logic. CORS headers are configured for public access in the Netlify deployment. The `generateCandlestickChart` function (present in the Netlify function but not `src/index.ts`) is safe, transforming numeric data into ASCII art within bounded dimensions. Overall, the implementation is solid for its purpose as a data proxy.
