Secret Handling

No auth is documented; HTTP/SSE exposure could enable unrestricted data access if bound publicly. TLS enforcement for HTTP/SSE is not specified in the README. Dependency hygiene cannot be verified from provided content; relies on several third-party libraries (mcp, fastmcp, vnstock, python-toon, pandas-ta).

Best When

Used by MCP-capable agents/clients that want to query Vietnam market data via MCP transports (especially stdio for desktop clients).

Avoid When

When you require strict guarantees about data provenance, availability SLAs, or strong access control; also avoid exposing HTTP transports to untrusted networks without additional security controls.

Use Cases

• MCP client access to Vietnam stock quotes and historical prices
• Retrieving company overviews, financial statements, and trading statistics
• Accessing fund NAV/holdings and market data
• Fetching gold prices and exchange rates

Not For

• Production systems requiring official/vendor-supported compliance guarantees
• Use cases needing built-in authentication/authorization per client
• Workloads that cannot tolerate potential upstream changes in vnstock or external data sources

Known Gotchas

⚠ SSE/HTTP transports require correct host/port/path configuration; mismatch can prevent clients from connecting.
⚠ If using stdio transport, ensure client config passes no extra stdio args and matches the command correctly.
⚠ Rate limiting/backoff behavior is not documented; agents may need to self-throttle.

Alternatives

Directly use the vnstock Python library in your own service Use other official/hosted market-data APIs (if available for Vietnam) Wrap vnstock yourself with an MCP server using a more security-focused reference implementation
