Worthbase MCP server
Your household's net worth in any AI assistant. Connect Worthbase to Claude, ChatGPT, Cursor, Raycast or any app that speaks the Model Context Protocol, and keep everything your household owns and owes: shares and ETFs, crypto, gold and silver, retirement accounts, property, cash and loans, in any currency and owned by people, trusts or companies. Hand your AI a broker export or a statement to record, and ask what you're worth, how your investments did, or what selling would make.
https://worthbase.app/mcp
A hosted, remote server (Streamable HTTP). There's nothing to install and no API key: the first time a tool is used you sign in to your own Worthbase account in the browser and approve the connection.
This repository holds connection instructions and configuration only. The Worthbase service and its server code are not here.
Try asking
- "What's our net worth, and how has it changed this year?"
- "Here's my broker's transaction export. Import it, owned 100% by me, and show me the preview first."
- "How did my shares do over the last three years, as an annual return?"
- "What would selling half my ETF holding make, and which lots would it use?"
- "Which of our values are out of date?"
- "Show my Worthbase dashboard."
Every write is previewed first and saved only when you approve it. Every change is audited and can be undone. Worthbase calculates every figure with exact decimals, and your AI quotes them rather than doing the maths itself.
