Part of the AndroJack MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call android_kmp_guide 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 android_kmp_guide 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.

Complete Kotlin Multiplatform reference — shares business logic across Android and iOS. CRITICAL: AI tools silently generate Android-only code for KMP projects. Retrofit cannot be used in KMP (use Ktor). Hilt cannot be used in commonMain (use Koin). Room 2.7+ has KMP support — use room-runtime + sqlite-bundled, NOT the Android-only Room. 900+ new KMP libraries in 2025. Room, DataStore, Ktor all have KMP variants. Topics: 'overview' (project structure, Gradle setup), 'libraries' (KMP catalogue — Ktor, Room KMP, DataStore KMP, Koin, Coil3, kotlinx-*), 'room' (Room KMP database setup), 'ktor' (Ktor HTTP client — replaces Retrofit), 'expect actual' (platform-specific code pattern).. 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 android_kmp_guide. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AndroJack MCP MCP server.
android_kmp_guide 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 android_kmp_guide 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 android_kmp_guide. 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.
android_kmp_guide 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.
Open source. One binary. Zero dependencies.
