However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; jadx-ai-mcp is Java. - License: caveman is MIT, jadx-ai-mcp is Apache-2.0. - Tags unique to caveman: caveman, tokens, claude-code, anthropic. - When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content. ### Choose jadx-ai-mcp if… - jadx-ai-mcp is primarily Java; caveman is JavaScript. - License: jadx-ai-mcp is Apache-2.0, caveman is MIT. - Tags unique to jadx-ai-mcp: mcp-server, llm, model-context-protocol, mobile. ## When NOT to use caveman - When requiring complex and detailed prompts that necessitate more nuanced expression beyond simple, 'caveman'-style sentences. - For situations where adherence to formal or specific linguistic structures is mandatory for the task's success. ## When NOT to use jadx-ai-mcp - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## Common questions ### What is the difference between caveman and jadx-ai-mcp? caveman: Reduce token usage with concise 'caveman'-style prompts.. jadx-ai-mcp: Plugin for JADX to integrate MCP server.
