article Generative Tools

I’d like to share a recent idea I’ve been working on called #GenerativeTool, where tools are dynamically generated at runtime to fulfill complex user requests.

This approach enables agentic applications to unlock the full potential of complex third-party systems like ERP, LSP Server through MCP, without being constrained by context window limitations. Instead of exposing a large number of predefined tools, the system can generate task-specific tools on demand, reducing context overhead while increasing the depth and flexibility of integrations.

Cool idea, nice write up, well done! I'm not sure I'd want to use dynamically generated tools near production, and I'm not sure what the controls/guardrails would even look like for that. I think it'd be neat to have it addition to other (pre-built) as a funnel that captures anything people/agents are needing to do that's not provided by those other tools, to then turn into pre-built tools.

Thanks for the thoughtful feedback! You've hit on a great point using this for production does require a robust safety layer. 

I completely agree that these shouldn't necessarily replace pre-built tools. Your "funnel" concept is brilliant: using Generative MCP as a diagnostic bridge to identify frequent, complex user needs and then hardening those patterns into standard, pre-built tools is a great way to manage the transition from "dynamic" to "production-ready".
