Billy Mcp

Overview

Billy Mcp is a Model Context Protocol (MCP) server: Billy (billy.dk) accounting: invoices, journal entries, trial balance, with write protection. Because it speaks the Model Context Protocol, AI assistants can use Billy Mcp as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package billy-mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need BILLY_ACCESS_TOKEN. The current release is v0.3.2, published under the MIT license, with source at Thourum/billy-mcp on GitHub.

On mcp.site, Billy Mcp sits in the Finance category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
