# Hobby Supply Shopping Planner AI Agent Connect > Hobby Supply Shopping Planner MCP connects your AI client to your project needs and existing tool inventory. It prevents wasted spending by checking what you already own before suggesting new purchases. Your agent can compare shipping costs and generate optimized shopping lists to keep your hobby projects on track and under budget. ## Overview - **Category:** productivity - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_JzgWK3Yyt0x0OEbzCNo2erZLRIJ2Hr3fIKO16vAr/ai-agent-connect - **Tags:** procurement, budgeting, hobbyist, inventory, logistics ## Description You shouldn't have to buy a whole new set of tools just to start a single project. This MCP acts as a procurement specialist for your hobby work. It bridges the gap between your project goals and your actual workshop inventory. Instead of guessing what you need, your AI client can look at your specific project requirements and cross-reference them with the tools you already have on hand. This ensures you only spend money on the exact materials required to finish the job. Beyond just making a list, you can use it to run numbers on different shipping speeds or vendor options to see how they hit your wallet. It turns your AI agent into a logistics manager that keeps your hobby organized and your budget intact. ## Tools ### calculate_shopping_list This tool builds a custom purchase list by comparing what your project requires against the items you already have in your inventory and your remaining budget. ### check_user_inventory This tool scans your existing collection of tools to identify what you already own and can reuse for a new project. ### get_project_requirements This tool pulls the specific list of materials and equipment needed to successfully complete a defined hobby project. ### simulate_shipping_impact This tool calculates how different shipping tiers or vendor groupings change the total cost of your order. ## Prompt Examples **Prompt:** ``` I want to start a Miniature Painting Starter project. My budget is $50 and my user ID is user_123.
