Splitwise Mcp

Overview

Splitwise Mcp is a Model Context Protocol server that brings Splitwise expense and group management directly into Claude and other AI assistants. It lets you track shared expenses, settle debts, and manage friends' transactions through natural conversation with your AI.

The server runs locally via npx -y splitwise-mcp and communicates with your AI assistant over stdio. You'll need a Splitwise API key, provided through the SPLITWISE_API_KEY environment variable. Version v2.3.0 is available now under the MIT license, with full source code at chrischall/splitwise-mcp on GitHub.

Splitwise Mcp appears in the Development category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any MCP-compatible client. If you maintain this server, claim your listing here to earn a Verified badge and keep information current.
