MCP Integration — Ask Your AI About Your Finances

Some things you can ask

Ask anything about your finances in plain language — these are just a few examples of what your AI assistant can help with.

“

How much did I spend on food last month?

“

Which subscriptions are due this week?

“

Am I over budget this month?

“

What are my top 5 expenses?

“

How much have I spent vs earned this year?

“

Do I have any overdue loans or bills?

...and anything else about your finances. If the data is in Nexpenz, you can ask about it.

Set up in 4 steps

Takes under 5 minutes. You only need your AI client and the Nexpenz app.

Generate an API key

Open the Nexpenz app, go to Settings → MCP API Keys, and create a new key. Copy it immediately — it's only shown once.

Choose your AI client

Each AI client needs a slightly different config snippet. Use the tabs below to find the right one for your setup.

Add the config

Paste the config into your AI client's config file. The exact file path is shown in each tab.

Restart and start asking

Fully quit and reopen your AI client. On first use it will ask for permission to access Nexpenz tools.

{
  "mcpServers": {
    "nexpenz": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.nexpenz.com/mcp",
        "--header",
        "Authorization:Bearer YOUR_API_KEY"
      ]
    }
  }
}

Replace YOUR_API_KEY with the key from Settings → MCP API Keys. mcp-remote is auto-installed via npx — no separate setup needed.

Built with security in mind

Read-only

Your AI assistant can query and analyse your data but cannot add, edit, or delete anything. All write operations must be done in the Nexpenz app.

Revokable at any time

API keys can be revoked instantly from Settings → MCP API Keys. Revoking immediately blocks all access for that key.

Key limits by plan

Standard plan allows up to 2 active API keys. Pro plan allows up to 5. This lets you use separate keys for different devices or AI clients.

Frequently asked questions

Does this work with ChatGPT or Gemini?

Yes. Nexpenz supports Claude Desktop, Cursor, ChatGPT (desktop), and Gemini CLI. Select your client from the configuration tabs in the setup section above.

Is my financial data sent to my AI provider?

Queries go from your AI client on your device to the Nexpenz servers. Nexpenz does not store or log your AI conversations. Your data is only fetched when you ask a question.

What if I lose my API key?

Revoke it from Settings → MCP API Keys and generate a new one. The old key is immediately invalidated.

Which plan do I need?

MCP access requires a Standard or Pro plan. Free plan users can upgrade from the Nexpenz app or the pricing page.
