Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "dfmi-market": {
      "command": "npx",
      "args": [
        "-y",
        "dfmi-market-mcp"
      ],
      "env": {
        "DFMI_BUYER_PRIVATE_KEY": "your-value",
        "DFMI_MAX_PRICE": "your-value",
        "DFMI_SESSION_BUDGET": "your-value",
        "DFMI_ALLOW_MAINNET": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add dfmi-market --env DFMI_BUYER_PRIVATE_KEY=your-value --env DFMI_MAX_PRICE=your-value --env DFMI_SESSION_BUDGET=your-value --env DFMI_ALLOW_MAINNET=your-value -- npx -y dfmi-market-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "dfmi-market": {
      "command": "npx",
      "args": [
        "-y",
        "dfmi-market-mcp"
      ],
      "env": {
        "DFMI_BUYER_PRIVATE_KEY": "your-value",
        "DFMI_MAX_PRICE": "your-value",
        "DFMI_SESSION_BUDGET": "your-value",
        "DFMI_ALLOW_MAINNET": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "dfmi-market": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "dfmi-market-mcp"
      ],
      "env": {
        "DFMI_BUYER_PRIVATE_KEY": "your-value",
        "DFMI_MAX_PRICE": "your-value",
        "DFMI_SESSION_BUDGET": "your-value",
        "DFMI_ALLOW_MAINNET": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

  • DFMI_SESSION_BUDGET env
    Total spend cap per server run (default 1.00).

Then ask: *"Find a market report on dfmi, check the price, and buy it."*

Limits (code, not prompt)

EnvDefaultMeaning
DFMI_MAX_PRICE0.10Max per purchase. The model may lower it per call, never raise it.
DFMI_SESSION_BUDGET1.00Total spend for one server run.
DFMI_ALLOW_MAINNEToffOnly dfmi dUSD points and Base Sepolia test USDC unless set to 1.
DFMI_BUYER_PRIVATE_KEY—Use your own throwaway key instead of ~/.dfmi/buyer-wallet.json.

dUSD is a points unit with no monetary value: claim it free from the faucet or buy it with a card on dfmi.app; it cannot be refunded or cashed out. Use a throwaway wallet only.
