You spend hours scrolling through listings just to get a vibe of the price, but that doesn't tell you what you'll actually see in your bank account after the platform takes its cut. This MCP changes that by giving your AI agent the data it needs to do the math for you. You can ask it to look at a specific item, like a three-year-old tablet, and get a realistic resale range based on its current condition. It handles the heavy lifting of calculating depreciation and estimating those pesky marketplace fees so you don't have to do manual math every time you list something. It also helps with the "should I?" questions. If a repair costs more than the item is worth, the agent can tell you straight up to let it go. It's a handy tool to have in your kit when you're trying to clear out clutter or run a small resale side hustle. You'll find it's a lot easier to manage your inventory when you have clear answers on what's worth the effort and what's just taking up space. You can find this and thousands of other tools in the Vinkius catalog to keep your workflow moving. ## Tools ### evaluate_disposal_utility Recommends whether you should sell, donate, or repair an item based on its value and condition.

Is it worth fixing? ``` **Response:** ``` Based on a market valuation of $250 for a working unit, a $120 screen repair leaves you with a low margin. It's better to sell it for parts or donate it. ``` **Prompt:** ``` What's the resale value of a 4-year-old MacBook Air in good condition? ``` **Response:** ``` The current market range is $350 to $450. Given the depreciation curve, you'll likely see the most interest at the $400 mark. ``` **Prompt:** ``` If I sell a bike for $200 on a site with a 10% fee, what do I keep? ``` **Response:** ``` After the $20.00 fee, your net proceeds will be $180.00. ``` ## Capabilities ### Get realistic resale price ranges The agent provides a price bracket based on the item's age and current condition. ### See your actual profit after fees It subtracts common marketplace fees from your sale price so you know your net payout. ### Decide between selling, repairing, or donating The agent recommends the best disposal path based on the value versus the cost of effort. ### Track depreciation based on item age It calculates how much value an item has lost over time to help with accurate listing. ### Analyze if repair costs make sense It compares the cost of fixing a broken item against its potential resale value. ## Use Cases ### Cleaning out a basement A user asks the agent to value a pile of old electronics. The agent identifies the best ones to sell and tells them to donate the rest. ### Repairing a cracked phone A seller wants to know if fixing a screen is worth it. The agent compares the repair cost to the estimate_market_valuation and advises against it. ### Setting up a Poshmark shop A new seller uses calculate_net_proceeds to ensure they are actually making money on clothes after the platform fee. ### Inventory auditing A small business owner checks the depreciation of their used equipment to decide when to cycle out old stock. ## Benefits - Stop guessing on prices by getting specific resale ranges for items based on their actual age and condition using estimate_market_valuation. - See your real profit instantly with calculate_net_proceeds so you know exactly what hits your bank account after fees. - Save time on research by letting your agent handle the depreciation math for every single item you want to move. - Make smarter inventory choices by using evaluate_disposal_utility to see if a repair is a waste of money. - Avoid loss leader mistakes where you sell something for less than it costs to list or ship it. - Get clear guidance on whether to donate or sell items that have lost too much value to be profitable. ## How It Works The bottom line is you get a clear financial roadmap for any used item without the manual research. 1.
