What is MCP (Model Context Protocol) in trading?

MCP is an open protocol that lets AI assistants connect to external data sources and tools through a standard interface. In trading, an MCP server exposes tools like get_holdings or get_quotes that the AI can call to read live account data — so answers come from your actual account, not from training data.

Which Indian brokers support MCP?

Zerodha launched the first broker-backed MCP server in India (Kite MCP, free at mcp.kite.trade) in 2025. It gives AI assistants read access to portfolio, margins, positions and market data, plus GTT-only conditional orders. Other Indian brokers have API programs but no official MCP servers at the time of writing.

Is it safe to connect my trading account to an AI assistant via MCP?

With the official broker-run MCP server, yes — by design: login and 2FA happen on the broker’s own pages, credentials never pass through the AI, access is read-scoped, order tools are limited to GTT conditional orders, and you can revoke access anytime. Third-party MCP servers deserve more caution — check who runs them and what scopes they request.

Yes. KitePilot runs on Kite MCP, Zerodha’s official (and free) bridge between AI assistants and your account. There is no developer setup and no paid AI subscription. Bring your own free AI key (for example Gemini), or use the built-in one.

Yes. Zerodha’s official Kite MCP service is completely free: no API key and no subscription. KitePilot is built on it, so connecting your Zerodha account here costs nothing.

Is there a daily limit on the free AI?

Yes. The built-in free AI (no key needed) allows 5 messages per day. Add your own AI key in Customize for unlimited use; your key stays in your browser. A free key from a provider like Gemini works fine.

Does Zerodha have AI trading?

No. Zerodha deliberately does not offer AI-driven trading. It offers Kite MCP, a read-only bridge that lets AI assistants see your live portfolio. The only order type allowed is a GTT, a price alert you set in advance. KitePilot wraps that in a friendly interface, and every order draft needs your explicit approval.

Can I use Zerodha MCP with Claude?

Yes. Claude Desktop, Cursor, VS Code and Windsurf can all connect, but that route asks you to install Node.js and edit a JSON config file. KitePilot gives you the same live Zerodha data in your browser with zero setup, and it works around the message limits Claude’s free plan hits on large portfolios.

Is it safe to connect my Zerodha account to an AI?

Yes. Your login happens on Zerodha’s own secure page, so your password and OTP never reach us. The AI can look at your portfolio but cannot place instant trades. The only orders it can draft are price alerts, and every draft waits for your approval.

Do I need to install Node.js or edit config files?

No. KitePilot exists to remove that hassle. You click Connect, log in with Zerodha, and start asking questions.

Can the AI place trades?

No instant trades, ever. The only order type is a GTT: a price alert you set in advance that goes through when your chosen price is reached. Nothing is sent until you approve the details.

Do I need a Kite Connect API key?

No. KitePilot uses Zerodha’s hosted Kite MCP, which needs no API keys at all. Only self-hosted, do-it-yourself setups need a paid Kite Connect app.

What is the difference between Kite MCP and Kite Connect?

Kite Connect is Zerodha’s toolkit for programmers building their own trading apps. Kite MCP is the newer, free bridge that lets AI assistants read your live portfolio (read-only, price-alert orders only). KitePilot uses Kite MCP, so there is no API fee.

Which AI assistants can I connect my Zerodha account to?

Zerodha’s official Kite MCP works with Claude Desktop, Cursor, VS Code and similar developer tools; Zerodha’s own support guide covers that setup. KitePilot is the no-setup option: a built-in AI assistant over the same live data, right in your browser.

Why do I keep getting “MCP error -32603: session not found”?

Kite MCP sessions expire. Zerodha resets them daily around 6 AM IST, and many AI setups drop the session mid-conversation. KitePilot keeps your session alive for you and tells you clearly when to reconnect. One click, not a debugging session.

Where does my data go when I ask the AI something?

Your questions, including your portfolio data, go to the AI provider you choose (for example Gemini or Anthropic, or an AI running on your own computer). Free AI services may review prompts to improve their models; paid plans generally do not. Your keys stay in your browser. For maximum privacy, connect a local AI.

What can’t the AI do?

It cannot place instant trades (price alerts only, always with your approval). It cannot see dividend history. AI can misread data: always verify numbers in Kite before acting. Outputs are informational and are not investment advice.

MCP for Trading: How Indian Brokers Are Opening Up to AI

Model Context Protocol (MCP) is steadily becoming the standard way software hands live data to AI assistants. Indian broking is now its most visible consumer use case. Zerodha's Kite MCP was the first broker-backed MCP server in India. Here is what the protocol actually is, what your broker exposes through it, and where it goes next.

MCP in one paragraph

Before MCP, an AI assistant knew two things: its training data and whatever you pasted into the chat. MCP (Model Context Protocol, open-sourced by Anthropic in late 2024) adds a third channel. The assistant calls tools on a server — get_holdings, get_quotes — and answers from live results. For trading, this is the difference between "generally, diversification matters" and "your top holding is 31% of your portfolio and you have no stop-loss on it."

Why Zerodha going first matters

Kite MCP (May 2025) made India's largest retail broker the first to offer a broker-run MCP server. It is free, at mcp.kite.trade. Its design choices are a model for how broker-AI integration should work:

Credentials stay home. Login and 2FA happen on Zerodha's own pages. The AI tool receives only a revocable session — never your password.
Read-mostly by default. ~22 tools covering profile, margins, holdings, positions, MF holdings, quotes, OHLC, historical candles, instrument search and order history.
GTT-only writes. Order tools are limited to conditional GTT orders. Market-order automation is left out on purpose — that is the regulatory and liability answer to "can AI trade for me?"
Consumer-grade access. No developer app, no API key, no ₹-per-month — unlike the classic Kite Connect path.

What AI assistants can and can't do with it

Can: answer account-specific questions from live data, produce portfolio analysis and risk reviews, maintain a trade journal, monitor GTT coverage, and draft protective GTT orders for approval.
Can't: place market orders, run unattended strategies, or act without your approval on anything involving orders. That is not an MCP limit. It is Zerodha's (and SEBI's) rule, built into the toolset itself.

Tools like KitePilot wrap this exact server in a browser UI — no config files, no Node, free. The guide covers the official Claude/Cursor route too, including the daily "session not found" error.

Where this goes next

More brokers. The pattern (broker-run MCP, read-only scope, GTT-style writes) is repeatable. Expect other Indian brokers to follow with their own servers.
Richer surfaces. MCP is gaining UI parts — tools that render as widgets rather than raw JSON — which suits trading dashboards well.
Agent standards for money. The hard problem is not technical. It is the approval and recovery model for financial actions. GTT with approval is the first serious answer, and it generalises.
Regulatory framing. SEBI's algo rules will keep automatic execution out of consumer AI. The winning products will be the ones that make the human-in-the-loop effortless.

Quick answers

Do I need to know what MCP is to use it? No — with KitePilot you just log in and chat.
Is MCP the same as an API? It is a protocol on top of APIs: same data, standardised tool interface for AI assistants.
Is my money at risk if I connect? The connection is read-scoped and revocable. GTT is the only write path, and each order needs your approval. The main risk to manage is which MCP client you trust. Prefer the official server or a UI that is transparent about it.
