Connect Normi to Windsurf (Devin Desktop)

Before you start

• A Normi account: sign in with Google, 500 free credits a month.
• For the API-key connection or the STDIO package: a normi_… key, created in Dashboard → Tokens. It is shown only once.
• For the STDIO package: Node.js 18 or later (npx).

Remote connection (HTTP Streamable)Recommended

Add this block and save. With no header, Devin Desktop detects Normi's OAuth sign-in: click Authenticate on the server's entry, sign in to normi.fr and approve the application.

{
  "mcpServers": {
    "normi": {
      "url": "https://mcp.normi.fr/mcp"
    }
  }
}

For a single project, use .devin/mcp_config.json at the repository root (or .devin/mcp_config.local.json, which Git ignores).

API-key variant

Export NORMI_API_KEY in your environment, then reference it with ${env:…}: the key never appears in clear text in the file.

{
  "mcpServers": {
    "normi": {
      "url": "https://mcp.normi.fr/mcp",
      "headers": {
        "Authorization": "Bearer ${env:NORMI_API_KEY}"
      }
    }
  }
}

Older Windsurf format (Cascade)

Installs still named Windsurf read ~/.codeium/windsurf/mcp_config.json and expect the serverUrl field. Open it from the … menu of the Cascade panel → MCPs section → “Open MCP config file”.

{
  "mcpServers": {
    "normi": {
      "serverUrl": "https://mcp.normi.fr/mcp",
      "headers": {
        "Authorization": "Bearer ${env:NORMI_API_KEY}"
      }
    }
  }
}

Alternative: STDIO package

If remote servers are blocked, run the npm package @normi/mcp-dvf locally. It relays calls to the same Normi server.

{
  "mcpServers": {
    "normi": {
      "command": "npx",
      "args": ["-y", "@normi/mcp-dvf"],
      "env": {
        "NORMI_API_KEY": "${env:NORMI_API_KEY}"
      }
    }
  }
}

A first prompt to try

The agent calls analyze_dpe_price_premium (10 credits). An excerpt of the real response, captured on 10 October 2026 against the 2014–2025 DVF data:

{
  "classes": {
    "A": { "count": 329,  "median_prix_m2": 3571, "vs_median_pct": 4 },
    "C": { "count": 2474, "median_prix_m2": 3526, "vs_median_pct": 2.7 },
    "D": { "count": 4671, "median_prix_m2": 3395, "vs_median_pct": -1.1 },
    "F": { "count": 1103, "median_prix_m2": 3303, "vs_median_pct": -3.8 },
    "G": { "count": 418,  "median_prix_m2": 3440, "vs_median_pct": 0.2 }
  },
  "summary": "Class A homes sell at +4% vs. median; class F at -3.8%"
}

In central Nantes the gap between classes is clear: +4% above the median for class A, -3.8% for class F. These medians describe the market; they are not adjusted for location or year of sale.
