    The best personal finance MCP servers

    The Model Context Protocol lets an AI assistant call tools against your real data instead of guessing from what you paste into a chat. For personal finance that is a genuinely new capability, and the field is about a year old, so the honest state of it is: a handful of products, most read-only, none of them household names. Here is what each one actually does.

    Prices checked August 2026. We build one of the products on this list — see how the ranking was made below.

    How this list was made

    • Ranked on what the server can do with your data, not on brand: number of tools, whether it can write as well as read, and whether it works with the assistant you already use.
    • Read-only is treated as a limitation, not a feature. It is a real safety choice, and it also means the assistant cannot finish the job.
    • Every entry notes where your data goes. No MCP server can keep your figures away from your AI provider — the assistant reads them, so its model provider sees them. Any product implying otherwise is misleading you.
    • We build one of these, so read the entries for the others as what they publish, not as hands-on testing.

      That's us

      Anyone who wants the assistant to act, not just look — and who wants a choice about where the data lives.

      €7/mo or €63/yr cloud; €45 one-time for the local desktop app

      Strengths

      • 46 tools covering net worth, accounts, income, expenses, goals, plans, forecasts and templates.
      • Read and write: the assistant can run a forecast and then save the plan, not just report a number.
      • The same 46 tools whether they run against the EU cloud or a file on your own Mac — the local build needs no account and no server.
      • Multi-currency and European Open Banking underneath, so the numbers the assistant reads are live.

      Limitations

      • European bank coverage; US accounts must be added manually.
      • No free tier — 7-day trial, then paid.
      • Practically Claude-first: ChatGPT Plus and Pro accounts cannot add custom MCP servers, which is OpenAI's restriction rather than ours.

      The most complete toolset here, and the only one that runs identically on your own machine.

      Era

      People who want a polished consumer app first and the MCP surface as a bonus.

      See vendor — consumer app with paid tiers

      Strengths

      • Positions squarely as personal finance for Claude, ChatGPT, Codex and Gemini, with the broadest assistant support claimed.
      • Bank connections, rules and savings goals in a mature consumer product.
      • Publishes genuinely useful writing on using an assistant for money questions.

      Limitations

      • US-centric account coverage.
      • The MCP layer sits on top of their app; you are adopting the whole product, not just a server.

      The strongest all-round consumer product in this list if you bank in the US.

      Spendify

      Spending analysis and category questions, read-only by design.

      See vendor

      Strengths

      • 30+ tools for transactions, spending by category, budgets and recurring charges.
      • Deliberately read-only — the assistant cannot move money, which some people will rightly prefer.
      • Clear, well-written setup documentation.

      Limitations

      • Read-only, so the assistant can answer but cannot act.
      • Transaction-and-budget shaped; no multi-year forecasting.

      A good choice if you want an assistant that observes your spending and nothing more.

      BudgetSmart

      Granular control over exactly what the assistant may see.

      See vendor

      Strengths

      • Separate permissions for balances, spending summaries, budgets and goals.
      • Read-only, and explicit that it never needs your bank login.

      Limitations

      • Read-only.
      • Younger product with a narrower toolset than the others here.

      The most cautious option, and the best fit if permission granularity is your first concern.

      Truthifi

      Investors who want fee and benchmark analysis rather than day-to-day finances.

      See vendor

      Strengths

      • Focused on portfolio intelligence: underperformance, fee levels, returns against benchmark.
      • Works with both Claude and ChatGPT.

      Limitations

      • Investment-only — not a general personal-finance server.
      • Read-only.

      Not a competitor to the others so much as a different tool; useful alongside one.

    The bottom line

    The split here is simple: read-only servers are safer and cannot finish a task; write-capable ones can act and ask more trust of you. Whichever you choose, be clear-eyed that your figures reach your AI provider the moment the assistant reads them.

    Wealthos
    For when you want the assistant to act — run the forecast, save the plan — and want a say in whether that happens in the cloud or on your own machine.
    Era
    For a polished consumer app with the MCP surface included, if you bank in the US.
    Spendify
    For spending and category questions, read-only. The most established of the servers that deliberately cannot act.
    BudgetSmart
    For when permission granularity is your first concern — separate control over balances, spending, budgets and goals.
    Truthifi
    For investment questions specifically: fees, benchmarks, underperformance. Sits alongside one of the others rather than replacing it.
