Overview

Description from the maker (original English)

Ask your AI about bank accounts, spending, budgets, debts, holdings, and investment activity.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Common questions

Is OpenBudget MCP Server safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

OpenBudget MCP Server

Your bank accounts, spending, debts, and investments are available to your AI assistant.

OpenBudget is a hosted Model Context Protocol (MCP) server that gives Claude, ChatGPT, Cursor, Codex, and other MCP clients access to your financial data. That includes transactions, balances, net worth, credit cards, loans, mortgages, investment holdings, and investment activity synced from US institutions through Plaid. You can also add physical cash, gift-card balances, real estate, private-company interests, and other assets you track yourself.

You don't run anything. The server is hosted on OpenBudget's infrastructure. You add one URL to your client, sign in once, and start asking.

https://api.openbudget.sh/mcp
  • Transport: Streamable HTTP (remote MCP server)
  • Auth: OAuth 2.0; sign in with your OpenBudget account
  • Plans: Base is $60/year or $9.95 month-to-month. Investor is $99/year or $12.95 month-to-month. Both start with a 7-day free trial.
  • Data: your own bank, brokerage, and retirement accounts connected through Plaid, plus assets and activity you add yourself

Plaid connections provide read-only financial data. OpenBudget never stores your financial-institution credentials, and your AI assistant cannot move money or place trades. Every write stays inside your OpenBudget account: categories, notes, rules, manual accounts, custom holdings, and custom activity.

Any other MCP client

Add a remote / custom MCP server over the Streamable HTTP transport, pointing at https://api.openbudget.sh/mcp. Most clients also accept the mcpServers JSON shape shown in the Cursor section above. The first call opens your browser to sign in and approve access.

What you can ask

The server exposes 26 tools, documented at [openbudget.sh/tools](https://openbudget.sh/tools). Ask in your own words and your client picks the right one. New connections receive read access by default; approve editing access (openbudget:write) to use mutation tools.

Base tools
ToolWhat it does
list_accountsEvery linked account with balances, institution, and a normalized net-worth view.
search_transactionsSearch and filter transactions by text, category, account, date range, or amount, with settlement links and merchant location details when Plaid supplies them.
get_liabilitiesCredit cards, student loans, and mortgages: APRs, due dates, minimum payments, payoff data.
get_liability_historyHow those liabilities changed over time, including APR moves, balance trends, and YTD interest.
list_available_categoriesThe full transaction category taxonomy.
list_categorization_rulesYour auto-categorization rules, in evaluation order.
search_budgetsReturn matching budget summaries with bounded pagination, including current progress for fixed or recurring periods.
get_budgetGet one budget by ID with its current period, history, rollover, comparisons, buckets, and optional audit events.
update_transaction*(write)* Recategorize a transaction, add a note, split it, hide it from searches, or include/exclude a transaction or split from budgets.
create_transaction*(write)* Log an off-bank purchase made with physical cash, a gift card, or store credit.
delete_transaction*(write)* Remove a manually-created transaction (bank transactions are hidden with update_transaction instead).
upsert_manual_account*(write)* Create or update a manual off-bank account such as a cash wallet or gift-card balance.
delete_manual_account*(write)* Delete an owned manual account with a zero or untracked balance and no transactions, holdings, or investment activity. Connected bank accounts are protected.
upsert_budget*(write)* Create, edit, or archive fixed and recurring budgets with category buckets and rollover policies. Archived budgets remain available in history; create a new budget when planning resumes.
save_categorization_rule*(write)* Create a rule once, such as "payments to our nanny are childcare," and optionally attribute future matches to a budget.
delete_categorization_rule*(write)* Remove a rule.
update_liability*(write)* Note or manual balance override on a credit card or loan.
Investor tools

Investor includes every Base tool and adds the tools below.

ToolWhat it does
search_investment_holdingsFilter connected and custom positions by account, ticker, name, category, source, or closed status, then sort by value, quantity, name, or ticker. Returns the position data your AI needs to calculate allocation, gains, and concentration.
search_investment_transactionsSearch buys, sells, dividends, interest, contributions, withdrawals, fees, taxes, property activity, and adjustments.
list_available_investment_categoriesReturn the separate category taxonomies for holdings and investment activity.
update_investment_holding*(write)* Categorize a holding, change its display fields, or manage its notes. Custom holdings also support value, quantity, price, cost basis, ticker, currency, and status changes.
update_investment_transaction*(write)* Categorize investment activity, add a note, or ignore it. Custom activity also supports amount, date, quantity, price, fees, ticker, and currency changes.
create_investment_holding*(write)* Add real estate, private-company interests, collectibles, offline positions, or other custom assets.
delete_investment_holding*(write)* Delete a custom holding. Connected holdings remain synced from the institution.
create_investment_transaction*(write)* Add property purchases, distributions, private contributions, fees, valuation adjustments, and other custom investment activity.
delete_investment_transaction*(write)* Delete custom investment activity. Connected activity can be ignored instead.

Transaction results can include pendingTransactionId, which links a posted transaction to its earlier pending record, and a structured location with address, city, region, postal code, store number, latitude, and longitude. These fields make receipt reconciliation reliable when a tip or pre-authorization changes the settled amount.

Example prompts
  • *"How much did I spend on restaurants last month, and how does it compare to the month before?"*
  • *"What did the Denver trip in March cost me all-in: flights, hotel, food, and rideshares?"*

Read-only financial connections

Bank, brokerage, and retirement connections go through Plaid with read-only data access. OpenBudget never sees or stores your financial-institution credentials. Your AI assistant cannot move money, initiate transfers, place trades, or modify anything at your institution. Every write stays inside your OpenBudget account: transaction and investment categories, notes, ignored flags, splits, rules, liability overrides, manual accounts, custom holdings, and custom activity. Every tool declares MCP annotations (readOnlyHint, destructiveHint) so clients can show what each call can do.

OAuth grants your AI client access to your own financial data in OpenBudget. See the Terms of Service, Privacy Policy, and Security pages.
