Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

ChargeGuard helps online merchants fight chargebacks: reason-code intelligence, response deadlines, and a free store audit.

Tools

4 advertised

list_reason_codes — list reason codes
Advertised by the server during the last successful anonymous check.

List the 9 card-network chargeback reason codes covered by ChargeGuard (Visa, Mastercard, Amex) with one-line summaries. Use first when the user mentions a chargeback without a code.

list_reason_codes input schema
{
  "type": "object",
  "properties": {}
}
lookup_reason_code — lookup reason code
Advertised by the server during the last successful anonymous check.

Look up one card-network chargeback reason code: what it means, the evidence that wins the representment, the response window, and the full guide URL. Accepts the code (e.g. '13.2') or a slug fragment (e.g. 'visa-13-2').

  }
}
get_response_deadlines — get response deadlines
Advertised by the server during the last successful anonymous check.

Response windows merchants have to fight a chargeback, per gateway (Stripe, PayPal, Braintree, Adyen, Shopify Payments) and per card network (Visa, Mastercard, Amex).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http chargeguard-mcp https://www.trychargeguard.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add chargeguard-mcp --url https://www.trychargeguard.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable chargeguard-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "chargeguard-mcp": {
      "url": "https://www.trychargeguard.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

      "url": "https://www.trychargeguard.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http chargeguard-mcp https://www.trychargeguard.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
