Try asking

“Which income deals are still unsettled?”
The AI lists income deals with status unsettled, with partner, due date and amount.
“Record a 5,500 yen expense for office supplies dated today.”
It looks up the account item and tax code and creates an expense deal with one detail line. This writes to your books.
“What is our profit and loss for this fiscal year?”
It gets the profit and loss trial balance for the fiscal year, and can break it down by partner, item or section.

What your AI can do

Deals and journals

List, create and update income and expense deals, record payments against them, and create manual journal entries.

Invoices and expenses

Read invoices, quotations and expense applications with their lines, amounts and status, and list File Box receipts.

Partners, banks and reports

Search, create and update partners, read bank and card statement lines, and get the balance sheet and profit and loss.

“Record that deal 12345 was paid from our main bank account today.”
It finds the bank account among your wallets and records a payment line on the deal. This books the payment; it does not move money.
“Add Sakura Trading as a new partner with their invoice registration number.”
It searches partners first to avoid a duplicate, then creates the partner with name and registration number.
“Show last month's lines on our company credit card.”
It finds the card among your bank accounts and cards and lists its statement lines for that date range.

Questions

What can the AI do in freee Accounting?

The AI can read deals, invoices, quotations, manual journals, expense applications, partners, account items, tax codes, items, sections, bank accounts and cards with their statement lines, File Box receipts, and the balance sheet and profit and loss. It can create and update deals and partners, record deal payments, create manual journal entries and delete deals.

Does the AI see my freee credentials?

No. Your freee Client ID and Client Secret are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only with reports and lists. Creating deals and journal entries writes to your books, and deleting a deal is permanent, so those can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

freee connects with OAuth, and OAuth connections need the PipMCP Pro plan or above. PipMCP also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task. You also need your own freee account.

Can the AI move money in freee?

No. record_deal_payment only books a payment line on a deal; it does not move money between accounts. The AI can read bank and card statement lines, but it cannot make transfers.
