Billium

Overview

Billium is a Model Context Protocol (MCP) server: Official Billium MCP server: manage crypto invoices, payments, and webhooks from any MCP host. Because it speaks the Model Context Protocol, AI assistants can use Billium as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package @billium/mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need BILLIUM_API_KEY, BILLIUM_MERCHANT_ID. The current release is v0.1.3, published under the MIT license, with source at BilliumHQ/billium-node on GitHub.

On mcp.site, Billium 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.
