Overview

AI-generated overview

ChargeGuard gives an assistant chargeback reference data: card-network reason codes, winning evidence, gateway response deadlines, and a free store audit…

What you can do
  • List the nine covered Visa, Mastercard and Amex chargeback reason codes with one-line summaries
  • Look up a single reason code by code or slug to get its meaning, the evidence that wins representment, the response window and a guide link
  • Retrieve response deadlines merchants have to fight a chargeback, per gateway and per card network
  • Submit a free store audit request that reviews the payment setup and dispute risk and emails a written report
When to use it
Useful when a merchant asks about a chargeback, needs to decode a reason code, or wants to know how long they have to respond through a given gateway or card network. Also for requesting a free dispute-risk review of a store.
Requirements
Remote MCP endpoint at the provider's site; no packages, environment variables or headers declared. The audit tool needs a store URL and a contact email.
Before you install
The audit tool submits a store URL and contact email to a third party, which then emails a report; only send details you are willing to share. Reason-code and deadline data is reference material, not legal or financial advice.

Installation

In SourceWeft

  1. Open ChargeGuard Dispute Assistant 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/com.trychargeguard%2Fchargeguard/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

Other MCP clients

Add this to your client's mcpServers config.
