Kite Connect MCP

kite-connect-mcp

A self-hostable Model Context Protocol server for the Zerodha Kite Connect v3 API. Run it on your own machine or server with your own Kite Connect app, and let an AI assistant read your account, market data and orders. Every write is a dry run by default.

Status: beta (0.x). Every Kite Connect v3 capability is covered and tested offline against a fake Kite. The read tools, the margin and charge calculators and the ticker have also been checked against the live API; live writes (orders, GTTs, alerts, mutual funds) have not, so expect rough edges there and report them. Changes are listed in CHANGELOG.md. This project is not affiliated with or endorsed by Zerodha.

Why another Kite MCP server?

Zerodha publishes an official server (zerodha/kite-mcp-server) and hosts it at mcp.kite.trade. This project differs in three ways:

• It covers the whole paid Kite Connect API. That includes alerts, GTTs, order and basket margins, charges, position conversion, holdings authorisation, auctions, mutual funds and the WebSocket ticker.
• It's built for one person self-hosting. The daily token is persisted and shared by every client you connect.
• It has a safety layer for orders: dry runs, two-step confirmation, value caps, allow-lists, a kill switch, an audit log and rate limiting.

The full evaluation and reasoning are in docs/DECISION.md.

What you need

• A Zerodha account, and a Kite Connect app from the developer console.
  • Connect (paid, ₹500/month per API key) includes live quotes, the WebSocket and historical candles.
  • Personal (free) covers orders, GTTs, alerts, portfolio and margins, but no market data. Market-data tools return a clear "needs the paid plan" error.
• Python 3.11+ (or Docker).
• To place live orders: the order requests must come from a static IP registered in the developer console. This is a SEBI/NSE rule, in force since April 2026. Reads work from any IP.

The developer-console steps are in docs/KITE_SETUP.md: creating the app, the API key and secret, the redirect and postback URLs, the subscription, and the static IP.

Quick start (local, stdio)

# install
uv tool install kite-connect-mcp        # or: pipx install kite-connect-mcp  /  pip install kite-connect-mcp
# or run without installing:  uvx kite-connect-mcp --help
# or the image:               docker pull ghcr.io/techfreakworm/kite-connect-mcp

# configure: credentials from env vars or files (mode 600)
export KITE_API_KEY=your_api_key
export KITE_API_SECRET_FILE=~/.config/kite-connect-mcp/api_secret

kite-connect-mcp check-config   # validates settings, never prints credentials
kite-connect-mcp login --listen # prints the Kite login link and waits for the redirect (managed mode)
kite-connect-mcp status         # session and safety status

For login --listen, register http://127.0.0.1:8765/callback as your app's redirect URL. Every setting is listed in docs/CONFIGURATION.md.

Add it to an MCP client, e.g. Claude Desktop (claude_desktop_config.json) or any client that launches stdio servers:

{
  "mcpServers": {
    "kite": {
      "command": "kite-connect-mcp",
      "args": ["serve"],
      "env": { "KITE_API_KEY": "your_api_key", "KITE_API_SECRET_FILE": "/home/you/.config/kite-connect-mcp/api_secret" }
    }
  }
}

To run it on a server over HTTP, see docs/SELF_HOSTING.md. It covers systemd and Docker, a reverse proxy with TLS, bearer-token auth, and the login callback.

The safety model, in short

Guard	Default
Every write tool takes dry_run	true: validate, run the checks, preview the exact request and Kite's margin calculation; send nothing
Live trading switch	off (KITE_MCP_TRADING_MODE=dry_run)
Confirmation	a live write needs the single-use confirmation_token from a dry run of the identical call (or, if you opt in, an explicitly allow-listed instrument)
Value caps	₹10,000 per order, ₹50,000 per day, 20 live orders per day
Allow-lists	instruments, exchanges, products, varieties, order types, sides (all optional)
Read-only mode	KITE_MCP_READ_ONLY=true hides every write tool, and the HTTP client refuses write endpoints too
Kill switch	a file; a tool can switch it on, only a person can switch it off
Audit log	every dry run, refusal, live send and result, as JSON lines; the intent is fsynced before sending
Rate limits	kept under Kite's 1/s (quotes), 3/s (historical), 10/s (orders and the rest), 400 orders/min
Retries	reads back off and retry; writes are never retried. A timeout is reported as an unknown outcome: check the order book before trying again

Details: docs/SAFETY.md.

Sessions and the daily login

Kite access tokens expire every day at about 06:00 IST. A request token is single-use. Logging in again with the same API key invalidates the previous access token. So one app should have exactly one program that owns the daily login.

• managed mode (default). This server owns the login. The login tool (or kite-connect-mcp login) gives you the link. Kite redirects to this server's /callback, which checks the one-time state, exchanges the request_token, and stores the token with mode 600.
• external mode. Another program owns the login and writes a token file. This server only reads that file, picks up the new token every morning without a restart, and never writes, deletes or logs out that token.

Tools

58 tools in 11 toolsets (53 by default: the mutual-fund writes are opt-in). Tool names follow the official server where one exists, so prompts carry over. Pick toolsets with KITE_MCP_TOOLSETS and hide single tools with KITE_MCP_EXCLUDED_TOOLS; kite-connect-mcp tools lists what your configuration exposes.
