I Built an MCP Server for INDmoney — Ask Claude About Your Portfolio in Plain English

A developer built an MCP server for INDmoney that allows users to query their investment portfolio through Claude using natural language. The tool, rebuilt in Python with Playwright for persistent encrypted sessions, provides 14 read-only tools covering all INDmoney asset classes including stocks, mutual funds, gold, credit scores, and loans. The server maintains encrypted sessions with AES-256-GCM, eliminating the need for repeated OTP logins after the initial connection.

INDmoney is great. The problem is I can't open it "just to check something." Every time I do, I'm there for two hours — tapping through charts, reading stock articles, checking what changed since yesterday. I also just started investing seriously. And staring at green/red numbers doesn't actually tell me if I'm doing things right. So I built something that lets me check my portfolio by asking Claude — without ever opening the app. "How are my mutual funds performing?" "Am I over-indexed on mid-caps?" "What's dragging my Experian credit score down?" Live answers, from your actual INDmoney account, right inside Claude. Model Context Protocol MCP is an open standard from Anthropic that lets Claude connect to external tools and data sources. Think of it like USB-C for AI — a standard port that any app can plug into. Once an MCP server is running locally, Claude can call its tools the same way it uses any built-in capability. No copy-pasting, no screenshots, no switching apps. I had a first version in TypeScript. It kept breaking mid-request — INDmoney's session would expire while fetching data, US stocks would time out, and half the time I'd get an error, close the laptop, and just open the app anyway. Which is exactly what I was trying to avoid. The core problem: no persistent sessions. Every server restart meant a new OTP login. So I rebuilt it in Python with Playwright. Now sessions are encrypted with AES-256-GCM and saved to disk. Even after a server restart, you're still connected — no re-login, no OTP every time. indmoney-mcp-python — 14 tools covering every INDmoney asset class: | Tool | What it returns | |---|---| get holdings | Indian stocks — symbol, qty, avg price, P&L | get mutual funds | MF holdings — invested, current value, XIRR | get us stocks | US equities in INR | get gold | Digital gold, SGBs, ETFs | get liquid | Bank balances, FDs, EPF | get credit cards | Outstanding balances, due dates | get loans | Loan accounts, outstanding amounts | get debt | Bonds, NCDs, debt MFs | get credit score | Experian score + risk factors | get portfolio summary | Full aggregated P&L + asset allocation | Plus session management tools: broker connect , broker status , broker disconnect , discover endpoints .

From that point you're connected for 12 hours — even across server restarts. "Which of my mutual funds is underperforming its benchmark?" "Give me a full portfolio breakdown — what percentage is in stocks vs MFs vs US?" "Do I have any credit card dues this week?" "My gold ETF — is it up or down from what I invested?" As someone still learning, being able to ask "am I going in the right direction?" and get a structured answer from my actual numbers is genuinely useful. Claude can reason over the data, not just display it. It won't place orders or move money. Read-only, always. Honestly that's intentional — I don't trust myself with one-click investing while chatting with an AI at midnight. Your data also never leaves your machine. No third-party servers, no cloud sync. If you're an INDmoney user — especially if you're also figuring out investing as you go — give it a try. If something breaks, open an issue. I'm using it myself so I'll see it.
