Public MCP Server

A Model Context Protocol (MCP) server is a lightweight program that acts as a secure, standardised bridge allowing AI models to connect to external data sources, files, and software tools.

QuickFile has a public MCP Server that can be accessed from the following address:

https://mcp.quickfile.co.uk/mcp

To find it from inside QuickFile, go to Account Settings > Developer Console, click Options and choose MCP Server.

If you use Claude, QuickFile also has an official connector in Claude’s connector directory that needs no address. See Connecting to QuickFile from Claude for those steps.

What data can the MCP Server access?

The QuickFile MCP Server hosts a number of read-only tools that provide access to the following data types in your account:

Business details and VAT obligations
Sales invoices, estimates and recurring invoice templates
Purchase invoices
Bank accounts and bank transactions
Supplier and client records, including client contacts
Journals and ledger entries
Financial reports, such as profit and loss, balance sheet, ageing and chart of accounts

Authorisation

The MCP Server uses your QuickFile sign-in to give an application access to your account. To authorise it:

Open https://mcp.quickfile.co.uk/authorize in your browser.
On the Connect to QuickFile screen, enter your QuickFile account subdomain (the part of your QuickFile address before .quickfile.co.uk).
Click Continue.
On the Authorise Integration screen, review what the QuickFile MCP Server asks to do. Click Deny to stop, or Authorise Access to allow it.

Important: Only authorise access for applications and people you trust, and do not share any link or credential that gives access to your QuickFile data publicly or with anyone you would not want to view your account data.

Revoking access

You can remove an application’s access at any time from the Developer Console:

Go to Account Settings > Developer Console.
Click the Partner Authorisations tab. It lists each authorised application with its date, scopes, expiry and options.
Find the application, click Options and choose Revoke Authorisation.

Browsing MCP Server Tools

The QuickFile MCP Server exposes a number of tools that provide read-only access to your accounting data. You can use a tool like Postman to easily view and query the various tools within the MCP server.

Open Postman.
In your Workspace add a new item and select MCP.
In the address bar set the protocol to HTTP and enter the MCP Server address, https://mcp.quickfile.co.uk/mcp. Authorise access when you are prompted.
You will now be able to navigate the tools, customise the parameters and submit requests.

Using the MCP Server with Claude Desktop

You can also add the QuickFile MCP Server as a custom connector in Claude Desktop. Alternatively, use the official QuickFile connector from Claude’s connector directory: see Connecting to QuickFile from Claude.

In Claude Desktop, go to Settings > Connectors, click Add and choose Add custom connector.
Enter a name for the connector and the MCP Server address, https://mcp.quickfile.co.uk/mcp, then add the connector.
Authorise access when you are prompted.

You can now start querying your QuickFile financial data in Claude Desktop.

Troubleshooting

My AI tool gets a 403 error before I can sign in.

A 403 “browser signature banned” error from Cloudflare means the request from that tool was blocked before it reached QuickFile. Contact QuickFile support and say which tool you are using.

I cannot find QuickFile in Claude’s connector directory.

Add the MCP Server as a custom connector instead (see above), or follow Connecting to QuickFile from Claude.

I want the AI tool to create or change records, keep access for longer, or reach several accounts at once.

The MCP Server is read-only and connects one QuickFile account at a time. To ask for more, raise a Feature Request on the QuickFile Community, one request for each feature.
