Myfinance MCP server

MyFinance MCP

A remote MCP server for personal finance - log expenses by talking, snap receipt photos, import whole bank statements, and get budgets, trends and net worth computed for you, in any currency.

Website: myfinance-mcp.com · Free while in beta · Built by Rteam

Quick Start

Already hosted and ready to use - just connect it to your MCP client:

https://myfinance-mcp.com/mcp

On Claude.ai: Customize → Connectors → + → Add custom connector → paste the URL → Connect. Leave the OAuth Client ID and Client Secret fields empty - filling them breaks sign-in.

On ChatGPT: Settings → Apps → Create app → paste the URL → choose OAuth → Create.

On first connect you sign in with Google or register with an email and password. Your data persists across reconnections.

Why

• No app, no forms, no spreadsheet. "Spent 24.50 eur on groceries at Lidl" is the whole workflow.
• Every number is computed in SQL. The server owns the data and the math; the AI reads the results, it never guesses arithmetic.
• Any currency. Transactions keep their original currency; the FX rate to your base currency is frozen at transaction date, so history never rewrites itself.
• Statements in one message. Drop a CSV/PDF export; hundreds of rows import in one call with idempotent deduplication, hand-logged twins merged, totals reconciled.
• Personal vs business. Entity tag on accounts and transactions, filterable everywhere, included in CSV export for your accountant.
• Dashboards in the chat. Budgets, trends, summaries and accounts render as interactive panels (MCP Apps) right in the conversation.

Tech Stack

• Bun - runtime and package manager
• Express - HTTP layer
• MCP SDK - Model Context Protocol over Streamable HTTP (stateless)
• OAuth 2.1 - PKCE + dynamic client registration, Google sign-in optional
• Prisma + PostgreSQL - all money as numeric, all stats as SQL aggregates
• Docker - single container deployment
