Offers MCP server

Offers MCP

Every offer. One call.

Deep purchase intelligence for AI agents, applications, and humans. Point it at a product (free text like Sony WH-1000XM6 black, or a GTIN/UPC/EAN barcode), add an optional US zip code, and one call scans merchants in parallel to return live prices, true cost, delivery options, and trust insights. Robust, private, efficient results for agents, applications, and humans to make informed purchase decisions.

Robust. Built to be trusted:

• Live prices with true landed cost (price + shipping, the number that actually matters)
• Delivery windows for a given zip code
• Merchant trust scores (no pay-to-rank), with untrusted listings filtered
• Confidence scores on the product match and on every offer, so your agent knows when to assert and when to hedge. When we're not sure, the response says so instead of guessing
• A computed best trusted offer and fastest trusted offer, plus the full option list. The final call stays with your user
• Provenance on everything: every offer names its source and the moment it was checked (checked_at, cache status)

Private. Nobody watches users shop: no per-user tracking, no raw IPs stored; queries stay private: never sold, shared, or used for retargeting (details in Privacy).

Efficient. Shop many stores in seconds: one input fans out to multiple sources at once and comes back normalized into one structured contract you can build against. Repeat lookups return instantly. Use it for a cross-vendor price check from the store aisle or programmatic lookups inside your own application. Same tool call, same answers.

Free during v0. No signup. No API key. No commitment.

Any stdio-only MCP client

Use mcp-remote as a bridge:

{
  "mcpServers": {
    "offers": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://offers-engine.dexter-works.com/mcp"]
    }
  }
}

Client UIs move fast. If a menu path above is stale,

open an issue and we'll fix it.

Then ask your assistant something like:

Use Offers MCP to check if I'm getting a good deal on the Sony WH-1000XM6 at $398. I'm in 83702.
