# Buyer Inquiry Response Plan AI Agent Connect > Buyer Inquiry Response Plan MCP acts as a decision engine for secondary market sellers. It evaluates incoming buyer messages against your specific listing constraints, such as price floors, accepted payment methods, and shipping availability. Your AI client uses this to decide whether to accept an offer, decline a request, or hold an item for a buyer. ## Overview - **Category:** automation - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_pAe1gnTcAjTtZLT1IU7sRzroMekUNe7HvS17w5DE/ai-agent-connect - **Tags:** marketplace, seller-tools, negotiation, logistics, customer-service ## Description Managing a marketplace storefront means dealing with a constant stream of questions and lowball offers. This MCP takes that weight off your shoulders by acting as a logic layer between your buyer messages and your final decisions. Instead of manually checking if a price is too low or if you can actually ship to a specific zip code, you let your AI client do the heavy lifting. When a buyer sends a message, the MCP checks it against the rules you've set for your listings. It looks at your minimum acceptable price, your preferred payment methods, and your logistics capabilities. It then tells your agent exactly how to respond. You won't have to worry about accidentally agreeing to a deal that doesn't work for you. It keeps your professional boundaries intact by validating every negotiation and checking every delivery request before a word is even sent. You stay in control of the business logic while your AI handles the repetitive back-and-forth. ## Tools ### analyze_inquiry This tool evaluates a buyer's message against your specific listing constraints. It identifies if the request aligns with your set rules. ### check_logistics_feasibility Use this to determine if a requested delivery method is actually possible. It checks your shipping and pickup capabilities. ### generate_response_payload This tool builds the actual response text. It provides the specific wording and instructions for your agent to send to the buyer. ### validate_negotiation This tool checks if a buyer's price offer meets your requirements. It prevents you from accepting offers below your minimum. ## Prompt Examples **Prompt:** ``` A buyer asks: 'Can you ship this to New York for $50?' when the minimum price is $60 and shipping is enabled. ``` **Response:** ``` I'm sorry, I cannot ship this for $50. The lowest price I can accept is $60, and I can certainly arrange shipping to New York once we agree on the price. ``` **Prompt:** ``` A buyer asks: 'Is this still available? Can I pick it up tomorrow?', and the reservation policy allows holds. ``` **Response:** ``` Yes, it is still available! I can hold it for you until tomorrow for pickup. ``` **Prompt:** ``` A buyer asks: 'Do you accept PayPal?', but only Cash and Venmo are accepted. ``` **Response:** ``` I do not accept PayPal. I can only accept Cash or Venmo for this transaction. ``` ## Capabilities ### Constraint Validation Your agent checks buyer requests against your listing rules for price and payment. ### Logistics Verification The MCP confirms if you can fulfill a specific shipping or pickup request. ### Negotiation Guardrails It prevents accidental acceptance of offers that fall below your set price floor. ### Response Drafting The tool generates the specific text needed to reply to a buyer professionally. ## Use Cases ### Price Negotiation Automatically decline lowball offers that don't meet your minimum price requirements. ### Shipping Confirmation Verify if a buyer's requested delivery method is supported before you commit to the sale. ### Availability Management Handle requests for item holds or pickups based on your existing reservation policies. ### Payment Method Filtering Politely inform buyers when they request a payment method you do not accept. ## Benefits - Maintains price integrity by validating every offer against your minimums. - Reduces manual checking of shipping and delivery options. - Standardizes professional responses to buyer inquiries. - Prevents errors in negotiation by using strict listing constraints. ## How It Works Connect the MCP to your AI client to start automating your buyer communications. 1.
