Overview

AI-generated overview

Lets an assistant search merchant offers, view full details and verification records, and mint single-use redemption codes for offers the user accepts.

What you can do
The server exposes three tools. offers_find searches current offers by free-text query, category or place, returning active offers with title, pricing including the reference price a discount is measured against, validity window and location. offers_get returns one offer by id with full details, redemption terms, validity and the merchant's verification record, including accuracy statistics where the merchant has been independently measured. offers_accept claims a code offer for the user and returns a single-use redemption code plus how to redeem it.
When to use it
Useful when someone wants to browse or compare local merchant discounts and check whether a merchant's claims have been independently verified, then obtain a voucher code for an offer they have decided to take.
Requirements
A remote streamable HTTP endpoint at offers.mattherbert.ca; no packages, environment variables or headers are declared, and no authentication is declared.
Before you install
offers_accept mints a single-use redemption code tied to a specific offer, so it should only be called after the user has confirmed the details and decided to take that offer. Offer and merchant details come from a third party and should be checked before relying on them.

Installation

In SourceWeft

  1. Open Offers in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ca.mattherbert%2Foffers/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
