Requested from your assistant
Connecting to Muchita…
Your assistant asked for live prices on this product. The check runs in your own Chrome with the free Muchita Shopping extension, so your assistant gets verified offers for you to inspect before buying.
Only your chosen product, shopping country and check result go to Muchita. Your conversation stays in your chat.
MUCHITA + MCP APPS
Muchita checks the exact product in your own desktop Chrome. Your assistant gets verified item prices, shipping details and links you can open to buy directly from the store.
With MCP Apps, the interactive card shows progress and new offers as stores are checked. The card can keep updating after your assistant finishes its answer.
Connect Muchita first. Replace the sample product, variant and country with yours before sending.
Use Muchita when you have chosen a product and need current comparable store offers. It checks stores in the country you specify; it does not make purchases or promise coverage of every retailer.
ONE-TIME CONNECTION
Interactive cards need MCP Apps support. Use the platform guides for ChatGPT, Codex or Claude. Other clients need compatibility testing and may return offers as text.
No check link? Confirm Muchita is enabled in the conversation.
No Muchita account, API key or local server. Install the free Chrome extension when prompted; your check continues automatically.
Some custom HTTP clients may be blocked by our hosting provider. If your client cannot connect, use the ChatGPT or Codex guide or Claude guide with its platform endpoint. Otherwise, contact support.
Your conversation stays in your chat. Only the chosen product, shopping country and check result go to Muchita. Requests and results are deleted within one hour. Item prices are ranked; shipping is shown separately.
As of 5 October 2026, our OpenAI and Claude directory listings have been submitted and remain in review. These setup guides describe direct connections; submission does not mean directory approval.

FROM REQUEST TO EVIDENCE
Our recorded request: Sony WH-1000XM5 headphones in black, in Germany.
Muchita supplies a link for that request. Open it in desktop Chrome and install the extension if prompted. Keep the tab open; the check continues after installation.
You can see the stores being checked. In a supported live card, progress and verified offers update in your conversation. A text client retrieves the result through its connected tools.
The result gives comparable item prices, retailer links, shipping details and any known purchase conditions. You buy directly from the retailer.
We sent the exact headphone request through the generic MCP, opened its private link in Chrome, then retrieved the completed result. It returned three offers and disclosed that only 6 of 28 stores had been checked; some pages were blocked or failed to load.
One returned offer was eBay.de seller godebution: €199.99 item price, plus €9.90 shipping to the sample German destination. We separately opened that listing and confirmed model WH1000XM5B.CE7, black colour, new condition, the seller, availability and outright purchase price. The seller stated VAT was shown on invoices; no paid membership or coupon was needed for the displayed price.
This is a dated test, not a live offer. Shipping can vary by address. No order was placed, and checkout eligibility was not tested. This records the MCP-to-Chrome-to-result flow, not a conversation in a particular assistant. Start a fresh check for today's prices.
