Connect your money to any AI assistant.
Plutonus is a hosted MCP server that connects your bank accounts, cards, and brokerages to Claude, ChatGPT, and any assistant that speaks the Model Context Protocol. Connect once, then ask about your money in plain language — read-only, on your terms.
Streamable HTTP · OAuth 2.1 · read-only. New here? See the setup steps.
The read-only tools it can call.
Every tool is read-only. Your assistant calls them to answer questions about your money — it never moves it. Amounts come back as integer cents.
data__get_schemaList the tables and columns available to query.
data__execute_sqlRun a read-only query across your financial data.
data__null_ratesCheck per-column completeness for a table.
accounts__list_financial_accountsYour linked bank, credit, and investment accounts with balances.
accounts__check_account_balanceBalance, available balance, and credit utilization for one account.
The tools available in a session depend on the accounts you've connected and the scopes you approve when you sign in.
Read-only, and revocable.
Here's exactly what a connected assistant can and can't do — and how you stay in charge.
- Your linked account list and balances
- Transaction history — merchant, amount, date, category, account
- Spending breakdowns and cash-flow analysis
- The schema of your financial dataset, for read-only queries
- Move money, transfer funds, or pay bills
- Place trades or change account settings
- See your bank login — Plaid handles linking
- Write to or modify your financial data
You approve the connection
Connect over OAuth 2.1 and approve read-only access. The assistant gets a limited, revocable token — never your login credentials.
Revoke anytime
Disconnect any assistant in one click from Plutonus. Access stops immediately.
Every call is audited
Each tool call is logged with its arguments redacted and retained for 90 days. The data returned to your assistant is never stored by Plutonus.
Ask it anything about your money.
Once connected, talk to your assistant in plain language. A few starting points:
What did I spend on groceries last month?
How does my spending this month compare to my usual pace?
List my accounts and their current balances.
Find every subscription or recurring charge in the last 90 days.
Show my income vs. spending over the last 6 months.
Questions, answered.

Which AI assistants does this work with?
Any client that speaks MCP — Claude (Desktop, Web, Code), ChatGPT, Cursor, and a growing list of others. You connect Plutonus once and it works across all of them; your accounts and context live in Plutonus, not the model.
Can my assistant move money?
No. Plutonus is read-only — it can read balances and transactions and run analysis, but it can never transfer funds, pay bills, or place trades. Anything that moves money still happens in your bank's or brokerage's own app.
Do I need to install or configure anything?
No. Plutonus is a hosted server — there's no CLI and no config files. Paste the server URL into your assistant's connector settings and approve the connection.
How do I connect my bank accounts?
The first time your assistant calls a Plutonus tool, you'll securely link your accounts through Plaid. Plutonus never sees your bank login — Plaid handles it.
How is access secured, and can I revoke it?
You connect over OAuth 2.1 and approve read-only access; the assistant receives a limited, revocable token, never your credentials. Revoke any assistant anytime from Plutonus. Every tool call is audited, and the data returned to your assistant is never stored.
What data can my assistant access?
Your account list and balances, your transaction history, spending and cash-flow analysis, and the schema of your financial dataset — nothing else.
Why don't I see a certain capability?
The tools available in a session depend on the accounts you've connected and the scopes you approved when you signed in. Connect more accounts or re-approve to surface more.
