Ambrook's MCP Server is now available in Beta.

Request access to Beta features in Ambrook Pilot: https://ambrook.com/pilot

The Ambrook MCP Server lets AI assistants like ChatGPT and Claude read your Ambrook data so they can answer questions about your finances — transactions, bills, invoices, estimates, accounts, contacts, profit and loss, balance sheet, and more.

The connection is read-only: an assistant can look at your data but can't change anything in Ambrook.

Connection address: https://api.ambrook.com/mcp

Tips for using MCPs

Clarify dates: If you use relative dates like "last month" sometimes the assistant will query the wrong month or year. If you're getting unexpected data back for a query, ask the agent what dates it used, and consider using absolute dates.
Favor reports or scripts for math: AI assistants like ChatGPT and Claude are bad at raw math. You may get more accurate results if you ask the AI assistant to use the MCP work off of reports rather than reproduce their results, or ask it to write scripts to process results deterministically.

Getting started

When you connect, you'll sign in with Ambrook and approve access — your data is never shared without that approval.
Ambrook isn't yet listed in the ChatGPT or Claude connector directories, so you'll add it manually using the steps below.
If a connection fails or you see a "not found" error, your account may not have this feature turned on yet — contact Ambrook support and we'll enable it.

ChatGPT

Requires a paid ChatGPT plan (Plus, Pro, Business, Enterprise, or Edu) on chatgpt.com in a web browser.

Click your profile picture → Settings → Apps .
Click Advanced (bottom of the page) and turn on Developer mode

Back on Apps, click Create.
Fill in:
Name: Ambrook
URL: https://api.ambrook.com/mcp
Authentication: OAuth
Click Create . A window opens — sign in to Ambrook and approve access.
Start a new chat — The Ambrook MCP should now be available

Claude

Works on claude.ai and the Claude desktop app. On Team/Enterprise plans, an Owner adds the connector once (Organization settings → Connectors), then each member connects individually.

Open Settings → Connectors .
Click Add → Add custom connector... (or + → Add custom connector).
Enter the URL: https://api.ambrook.com/mcp and click Add .

You normally don't need Advanced settings; if asked, choose transport Streamable HTTP .
Click Connect — sign in to Ambrook and approve access.
Ambrook now appears in your connectors and Claude can use it in chats.

To change the connection later, remove it and add it again — Claude doesn't support editing a connector in place.

Grok

Works in Grok Bot. Grok's connector screen (grok.com/connectors) isn't supported yet, so add Ambrook from a Grok Bot chat instead.

Open a new chat in Grok Bot .
Type: Add a custom MCP server called Ambrook at https://api.ambrook.com/mcp
Check that the name and URL match, then click Add it .
Click Authorize on the connect card, then sign in to Ambrook and approve access.
Type @ in a chat and pick Ambrook to attach it to a task. The Ambrook MCP should now be available.

Grok Bot has no settings screen or config file for MCP servers, so asking in chat is the only way to add one.

Other AI assistants / MCP clients

Ambrook's server follows the open Model Context Protocol (MCP) standard, so most MCP-capable assistants can connect, including Cursor, VS Code (GitHub Copilot), Windsurf, Claude Code, Codex, and Gemini CLI. Whenever your assistant has an "add connector / add MCP server" screen, use that and paste the URL — it's the simplest path. Only fall back to the config-file method if your assistant has no such screen.

If your client supports remote MCP servers (Streamable HTTP with OAuth) — recommended: in your assistant's connector settings, add a server with the URL https://api.ambrook.com/mcp . A browser window will open for you to sign in to Ambrook and approve access.
Only if your client has no connector UI and supports local/command-based servers: use the mcp-remote bridge. Add this to your client's MCP config file (requires Node.js 18+ installed):

{
  "mcpServers": {     
    "ambrook": {       
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.ambrook.com/mcp"]     
    }   
  } 
}

The first time it runs, a browser window opens for you to sign in to Ambrook and approve access.

Ideas for what to ask

To get the ideas flowing, try asking the AI assistant:

How many transactions do I have left to tag in 2026, across both category and enterprise tags?
Do I have any overdue invoices or unpaid bills I should follow up on?
What's my average time-to-payment on invoices sent vs. received?

You can also generate ideas on your own that are more customized to your books by asking something like: "What are some interesting questions I could ask about my books?"

If you've played around with AI tools before, you'll know that it's very open-ended. Don't be afraid to get creative!

Troubleshooting

"Not found" / connection rejected: your account may not have Ambrook's AI connection enabled yet — contact Ambrook support.
Stuck on sign-in: make sure you're signed into the correct Ambrook account in your browser, then retry.
Assistant can't change data: that's expected — the connection is read-only by design.
