What you can do
  • Work with invoices in wFirma.pl
  • Manage contractors and their records
  • Handle payments
  • Retrieve accounting reports
  • Access is read-write, so the assistant can both look up and change data
When to use it
Useful when you run Polish bookkeeping on wFirma.pl and want an assistant to look up or update invoices, contractors, payments and reports without switching to the web interface.
Requirements
A remote MCP endpoint at fakto.app reached over streamable HTTP; OAuth sign-in is required. No environment variables or headers are declared. A wFirma.pl account is implied by the service it connects to.
Before you install
The server has full read-write access to accounting data, so an assistant can create or change invoices, contractors and payments. OAuth grants access to your wFirma.pl account; review the scopes requested and confirm changes before they are applied.

Installation

In SourceWeft

  1. Open Fakto.app — wFirma MCP Server in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.fakto%2Fwfirma/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
