Osome Model Context Protocol (MCP) connects your Osome account directly to your favourite AI assistant, such as Claude, ChatGPT, or Gemini. Instead of opening a browser tab, logging into your accounting portal, filtering through transactions, and downloading a CSV, you can simply ask. Request a profit and loss statement, upload an invoice PDF, or clarify a payment note, all without leaving your chat workspace. Setup takes under two minutes on Claude. If you run companies in more than one country, one connection covers all of them. And unlike other accounting MCPs, which just connect you to software, Osome MCP connects you to your accountant too.
Key Takeaways
- Osome MCP connects Claude, ChatGPT, or Gemini directly to your live Osome account.
- Any action that changes your books, such as categorising a transaction or issuing an invoice, needs your explicit confirmation before Osome updates it.
- Setting up Osome MCP takes about two minutes on Claude and does not require raw API keys or coding knowledge.
What Is Osome MCP?
Osome MCP is a secure connection between your Osome account and your AI assistant. It runs on Model Context Protocol (MCP), an open standard for linking AI assistants to business platforms. The Osome MCP server opens up a suite of 34 specialised financial tools, so your assistant can run real-time queries, retrieve reports, and carry out controlled accounting actions on your behalf.
Your assistant does not act independently. It suggests, retrieves, and drafts. Osome checks permissions, validates the accounting, and updates your ledger.
What Can You Do With Osome MCP?
Osome MCP spans three core operational areas: Accounting, Financial Reports, Company Records, and invoicing. Across these areas, you can run five main workflows straight from your chat bar. Pull a report, or sort out a single transaction, without opening a browser tab or waiting on your bookkeeper.
1 Instant financial reporting
Instead of exporting a static PDF, ask your assistant for live financial figures. Osome MCP gives you:
- Balance sheets and profit and loss (P&L) reports, showing real-time revenue, net profit, assets, and liabilities.
- Founder-grade summaries, covering quarterly revenue trends and year-to-date performance.
- Aged receivables and overdue lists, showing which clients owe you money and how many days overdue each payment is.
2 Invoicing and credit notes
Manage your entire invoicing cycle inside your AI conversation. Ask your assistant to:
- Draft an invoice for a client, amount, and payment term.
- Generate a PDF preview link automatically.
- Open and submit a credit note against an existing invoice.
- Filter invoices by status: draft, awaiting payment, overdue, paid, or cancelled.
Currency is just a line item on the invoice, so you can change it easily for clients billed in a different market.
3 Secure document uploads
Give your assistant invoices, receipts, and bank statements directly:
- Files upload straight to Osome storage, bypassing the AI chat itself, for fast and secure processing.
- Once uploaded, your document flows into Osome's standard accounting pipeline for extraction and processing.
4 Two-way transaction comments
Bookkeeping questions often stall in email threads. Osome MCP links transaction search directly to the comment thread on the Osome transaction page:
- Ask your assistant whether your bookkeeper left a note on a specific transaction.
- Reply to your bookkeeper, or add a note such as "Client lunch travel expense," directly from your chat window. The note attaches permanently to the transaction record in Osome.
5 Assisted cashcoding
Routine payment categorisation creates unnecessary friction:
- Ask your assistant to pull up Osome's recommended category for a transaction, such as identifying a Figma charge as "Software & Subscriptions." This comes from Osome's existing AI categorisation feature, which shows a shortlist of options rather than one fixed guess.
- Pick the right category from that shortlist, and Osome updates the record using standard document write permissions.
Osome MCP works on top of your existing books. If you have not set up Osome's accounting services yet, do that first, since every report and action above depends on the bookkeeping behind it.
How Do Startups and Freelancers Use Osome MCP Differently?
Startups tend to use Osome MCP for invoicing and receivables at volume. If you have entities in more than one country, such as Hong Kong and Singapore, one Osome MCP connection lets you query and act on both from the same conversation, with no differences between jurisdictions. Freelancers use it more for quick, one-off tasks, like payment clarifications and expense checks. Here is how that looks in practice:
Workflow for Startups & Growth Teams | Example prompt |
|---|---|
| Invoicing co-pilot | "Draft an invoice to Acme Corp for S$ 5,000 for consulting services, due in 14 days, and send me the PDF preview link." |
| Overdue receivables tracking | "Show me all overdue invoices for my Singapore entity and list who we need to follow up with today." |
| Batch document intake | "Upload this supplier invoice PDF directly to my company documents and mark it for processing." |
Here’s how it looks for freelancers and solo founders
Workflow | Example prompt |
|---|---|
| Quick payment clarification | "Check the comment on my S$ 240 payment from July 12 and reply that it was a business travel dinner with Sarah from TechCorp." |
| One-click expense categorisation | "What category does Osome recommend for my $ 20 payment to Figma, and can you apply it?" |
| Tax season spend audits | "How much did I spend on business software subscriptions and equipment year-to-date?" |
Is It Safe to Connect My AI Assistant to Osome MCP?
Osome MCP is built around strict enterprise safety guardrails. These guardrails cover how you log in, what your assistant can change, and how your data is used once it reaches Osome, in line with Osome's AI Governance & Data Responsibility Policy.
OAuth 2.1 authentication
Connecting your assistant does not require raw API keys. Authentication uses industry-standard OAuth 2.1 with PKCE (Proof Key for Code Exchange). You log in through a secure Osome browser pop-up and authorise access. You can revoke that access at any time, and it takes effect immediately.
Changes require your confirmation
Your AI assistant will never change your ledger without your confirmation. For any action that changes your books, such as categorising an expense or issuing an invoice, the assistant will show you the exact details, the recommended account, and the change first. The update only goes through once you confirm it.
Zero AI model training
Your financial data stays completely confidential. Osome MCP never uses your requests, typed questions, or uploaded documents to train public large language models (LLMs). Full details are in Osome's AI Governance & Data Policy.
Reconciled data shield
Transactions already verified and reconciled by your Osome accountant are automatically locked. If you or your assistant try to modify one, Osome MCP blocks the edit and directs you to review it inside the Osome app. This protects work your accountant has already checked against your bank records.
What Osome MCP Doesn't Do
Some limits are worth stating upfront, so there are no surprises once you are connected.
- Change your books without your confirmation. Every change is shown to you first, and only goes through once you confirm it.
- Edit a transaction your accountant has already reconciled. Reconciled transactions are locked. You will be directed to the Osome app to review them.
- Invent its own categories. Categories come from Osome's own AI categorisation, not from your AI assistant.
- Let anyone do more than their Osome role allows. Each person's access follows their own Osome permissions.
- Replace your bookkeeping, or work without an Osome account. You need an Osome account, with a registered company and Osome's accounting service behind it.
- Use your data to train AI models. Osome never trains AI models on your data.
- Control what your AI provider does with what it shows you. Check your AI assistant's own privacy and data settings for that.
- Work on ChatGPT's mobile app. On ChatGPT, Osome MCP currently works on the web only.
How Do You Set Up Osome MCP?
Connecting Osome MCP is quick, hassle-free, and requires no technical knowledge or coding skills. It's included on every Osome plan, as long as you have completed KYC and onboarded to the Osome app. This is the quickest on Claude. Paid plans of ChatGPT and Gemini can also connect, with a couple of extra steps covered below.
- Copy Your MCP Link: Locate your dedicated Osome server URL (https://mcp.osome.com/mcp) in your Osome workspace settings.
- Open Your AI Assistant: Navigate to the developer or tools section in Claude Desktop, ChatGPT, Cursor, Gemini, or VS Code.
- Paste & Authenticate: Add the Osome MCP URL. A secure pop-up window will prompt you to log into your Osome account and approve the connection.
- Start Asking Questions: You are ready. Start querying your books, uploading files, and drafting invoices directly in your chat.
Osome MCP assumes you already have an Osome account connected to a registered company. If you are setting up as a non-resident, Osome's foreign company incorporation service can get your entity registered first, so there is something for MCP to connect to.
How Osome Can Help
Osome already handles your bookkeeping, tax filings, and compliance in the background. Osome MCP brings that same service into the AI assistant you already use. This works whether you are a freelancer with a handful of clients or a startup finance team tracking receivables across entities. Ask directly, instead of waiting for a monthly report or logging into a separate portal. The answers you get will be based on the work that Osome's team has already completed for you.
Summary
Osome MCP lets you reach your bookkeeper and your Osome account through the AI assistant you already use. Start small. Connect it, then ask for something you already check regularly, like an overdue invoice list or last month's P&L. Try a change, such as drafting an invoice, only after that. After you have seen the confirmation step once, the rest of the workflow falls into place quickly.
