My Finance MCP Server

Bare-bones Model Context Protocol server that lets Claude store personal finance transactions and later query them via semantic search. Transactions are persisted in ChromaDB for vector search plus a JSON ledger for backup.

Run it alongside Claude Desktop and you get an AI bookkeeper that remembers your receipts, statements, and portfolios—then answers natural language questions about spending trends, allocations, or anything else you upload.

Setup

Install

uv sync

Run

uv run my_finance_mcp.py

Configure Claude Desktop

Add to ~/.claude_desktop_config.json:

{ "mcpServers": { "my-finance": { "command": "uv", "args": [ "run", "--project", "/path/to/my_finance", "/path/to/my_finance/my_finance_mcp.py" ] } } }

Usage

Say: "Store this transaction data"
Claude calls the MCP server to save it
Later ask: "How much did I spend on groceries last month?"
Claude searches your historical data via MCP

Example Claude Desktop interaction

User: Remember these portfolio positions for later analysis. Claude: I'll help you store your portfolio positions from the uploaded CSV file for later analysis. Let me read the file and process the data. Claude (tool call): Store transactions Claude: Perfect! I've stored your portfolio positions from November 6, 2025 in your finance system. Here's a summary of what was recorded: ... The data is now stored and ready for later analysis. You can query this information anytime using natural language searches about your portfolio positions, performance, or allocation patterns.
