Part of the AndroJack MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call kotlin_best_practices to retrieve information from AndroJack MCP without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though kotlin_best_practices only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Other tools in the Read risk category across the catalogue. The same policy patterns (rate-limit, allow) apply to each.
Returns official Kotlin and Android code patterns with ready-to-use snippets and explicit anti-patterns. All snippets are sourced from developer.android.com and kotlinlang.org. Call this when generating coroutine code, StateFlow/LiveData usage, Compose state, Room DAOs, Hilt injection, Navigation, or WorkManager tasks. Available patterns: coroutines-viewmodel, stateflow-ui, compose-state, room-dao, hilt-injection, navigation-compose, workmanager-task, sealed-result. Pass any topic keyword or call with no topic to list all patterns.. It is categorised as a Read tool in the AndroJack MCP MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for kotlin_best_practices. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AndroJack MCP MCP server.
kotlin_best_practices is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the kotlin_best_practices rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the Intercept policy for kotlin_best_practices. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
kotlin_best_practices is provided by the AndroJack MCP MCP server (androjack-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
