Splitwise Mcp
Expose Splitwise groups, shared expenses, settle-up flows, and friends to your agent while you build roommates apps, trip splitters, or finance copilots without reimplementing Splitwise’s REST surface
Overview
splitwise-mcp is a Build-phase MCP server that lets agents manage Splitwise shared expenses, groups, settle-up, and friends via SPLITWISE_API_KEY.
What is this MCP server?
- Splitwise MCP v2.0.8 (npm splitwise-mcp) for shared expenses, groups, settle up, and friends.
- Requires SPLITWISE_API_KEY from splitwise.com/apps/api as the only mandatory secret.
- stdio npm transport aligned with Claude Code style MCP configs.
- GitHub repo chrischall/splitwise-mcp for verifying tool coverage before production.
- Keeps agent reasoning anchored to real balances instead of guessed spreadsheets.
- Server version 2.0.8 on npm identifier splitwise-mcp
- stdio MCP transport
- One required secret environment variable: SPLITWISE_API_KEY
What problem does it solve?
Your agent cannot split bills or read real group balances in Splitwise until you hand-roll API clients and auth for every prompt.
Who is it for?
Solo builders creating agent-assisted finance or household apps that treat Splitwise as the ledger of record.
Skip if: Organizations that need corporate accounting, multi-currency treasury, or Splitwise features outside the MCP tool set without custom code.
What do I get? / Deliverables
After registering splitwise-mcp with a valid API key, agents can query and manage Splitwise data through MCP tools instead of manual app checks.
- Agent-driven Splitwise group and friend operations
- Shared expense and settle-up queries backed by live API data
Recommended MCP Servers
Journey fit
Splitwise connectivity is a Build concern: you add the MCP when implementing expense features or agent assistants that must call Splitwise’s official API with your key. Integrations is correct because splitwise-mcp wraps splitwise.com/apps/api with SPLITWISE_API_KEY over stdio—pure external finance API wiring.
How it compares
Splitwise API MCP connector, not a budgeting methodology skill or payment processor integration.
