Landfiller support

Help with the builder and MCP connection.

Contact support

Email [email protected] with the commander, constraints, error message, and whether you used the website or an MCP client. Include a build URL if available. Do not send passwords, access tokens, or payment information.

Connection troubleshooting

Use https://landfiller.app/mcp with Streamable HTTP and no authentication. A GET request returning 405 is expected: the server accepts MCP POST requests. If you receive 429, wait at least 60 seconds before retrying. Check your client supports a remote MCP connection.

Shopping and prices

Mass-entry shopping links match by name rather than printing. Prices and availability may change. TCGplayer handles orders and order support.
