Using AI Assistants

Integrate faster with Crossmint by ingesting the docs into your AI-based code helpers (like Cursor, GitHub Copilot, etc.).

Defaults for Coding Agents

When an AI assistant writes a Crossmint integration, it should follow these defaults unless you ask otherwise:

• Latest packages. Install the latest released @crossmint/* packages (npm view <package> version), not versions copied from an older app.
• Crossmint Auth in staging. In staging, if the app has no auth provider yet, sign users in with Crossmint Auth (CrossmintAuthProvider, and @crossmint/server-sdk on the server). An app that already has JWT auth keeps it, because its wallets are tied to that provider’s users: connect it with Bring Your Own Auth. For production, follow the Crossmint Auth guide. Saving cards (CrossmintPaymentMethodManagement) does not accept Crossmint Auth JWTs: use the app’s own auth provider or a custom JWT there.
• USDXM in staging. Use USDXM (usdxm) and fund wallets with wallet.stagingFund(amount), as in Fund a Staging Wallet. Use testnet USDC only where a product needs it, such as offramp.

Integrate with Cursor

1. Navigate to Cursor Settings > Features > Docs

2. Select “Add new doc” and paste the following URL:

https://docs.crossmint.com/llms-full.txt

3. Use @docs -> Crossmint to reference Crossmint’s docs in your code.

Crossmint Docs MCP Server

The Crossmint Docs MCP server searches the documentation. To let an AI assistant manage your console projects, organizations, and API keys, use the Crossmint MCP server.

The Crossmint Docs MCP server lets your AI assistant search and read the Crossmint docs when it needs them. It returns only the sections that match the query, not the full docs.

• URL: https://docs.crossmint.com/mcp
• Transport: Streamable HTTP
• Authentication: none

Installation

Claude Code

Run this command in your terminal:

claude mcp add --transport http crossmint-docs https://docs.crossmint.com/mcp

Cursor

Add the server to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

mcp.json

{
    "mcpServers": {
        "crossmint-docs": {
            "url": "https://docs.crossmint.com/mcp"
        }
    }
}

VS Code

Open the command palette (Cmd/Ctrl + Shift + P), select MCP: Open User Configuration, and add the server:

mcp.json

{
    "servers": {
        "crossmint-docs": {
            "type": "http",
            "url": "https://docs.crossmint.com/mcp"
        }
    }
}

Tools

The server gives your agent three tools. The agent selects the tool to use from your prompt.

Tool	What it does
search_crossmint_docs	Searches the docs and returns the matching sections, each with a title, link, and content.
query_docs_filesystem_crossmint_docs	Reads full pages and OpenAPI specs with read-only commands such as rg, cat, ls, and tree.
submit_feedback	Reports an incorrect, outdated, or incomplete page to the Crossmint docs team.

The server also exposes the Crossmint skill file as an MCP resource.

Example prompts:

• “How do I create non-custodial wallets for my users?”
• “How do I get a staging API key?”
• “Does Crossmint support Solana?”
• “How do I set up transfer webhooks?”
