Secret Handling

README provides no security guidance (auth method, token handling, TLS expectations beyond general HTTPS conventions, logging/redaction, or scope restrictions). Dependencies include FastMCP and keyring, suggesting potential for credential storage, but specific secret-handling practices are not documented.

Use Cases

• Agent-assisted workflows for tracking Roblox friend presence
• Displaying a list of friends currently in-game
• Launching/joining a friend’s game via deep links from an agent tool call

Not For

• Production-grade, fully documented public SDK/API consumption without additional engineering
• Applications requiring strong enterprise auth, auditing, or compliance-ready security controls

Known Gotchas

⚠ Authentication requirements for Roblox are not documented; agent calls may fail without required credentials/config.
⚠ Tool outputs/schemas are not shown in README; agent may need to infer response formats.
⚠ Rate limits, backoff, and retry behavior are not documented.
⚠ Roblox presence/join operations may be subject to Roblox platform constraints (rate limiting, access permissions, session/state).

Alternatives

Using Roblox platform-native presence/inventory features directly (where applicable) Building a small custom MCP server around Roblox APIs with stricter auth/security and robust schema/contracts Using a community Roblox integration library with its own maintained SDKs (if available)
