Crossmint MCP Server Tools

Reference for the tools the Crossmint MCP server exposes to AI assistants

The Crossmint MCP server exposes the following tools. Your AI assistant chooses which tool to call based on your request. To connect a client, see Connect the Crossmint MCP Server.

A connection is signed in to one environment (production or staging) and one organization. Every tool runs in that environment and organization.
