Kite MCP Server

A Model Context Protocol (MCP) server that provides AI assistants with secure access to the Kite Connect trading API. This server enables AI agents to retrieve market data, manage portfolios, and execute trades through a standardized interface.

TL;DR for Traders

Want to use AI with your Kite trading account? Just add `https://mcp.kite.trade/mcp` to your AI client configuration. No installation or API keys required - it's hosted and ready to use.

Features

• Portfolio Management: View holdings, positions, margins, and mutual fund investments
• Order Management: Place, modify, and cancel orders with full order history
• GTT Orders: Good Till Triggered order management
• Market Data Access: Real-time quotes, historical data, OHLC data
• Pagination Support: Automatic pagination for large datasets (holdings, orders, trades)
• Comprehensive Coverage: Implements most Kite Connect API endpoints
• Multiple Deployment Modes: stdio, HTTP, SSE, and hybrid mode (production)
• Built-in Documentation: Auto-served documentation at runtime

Quick Start

Hosted Version (Recommended)

The easiest way to get started is with our hosted version at `mcp.kite.trade`. Both `/mcp` and `/sse` endpoints are available - no installation or API keys required on your end.

Quick Setup: Add the following to your MCP configuration:

https://mcp.kite.trade/mcp

Recommended: Use the new HTTP mode (`/mcp` endpoint) for better performance and reliability. You can use mcp-remote to connect to the hosted server.

For self-hosting with your own API keys, follow the installation steps below.

Prerequisites

• For hosted version (recommended): Nothing! Just use `https://mcp.kite.trade/mcp`
• For self-hosting: Go 1.21 or later
• For self-hosting: Valid Kite Connect API credentials

Getting started

git clone https://github.com/zerodha/kite-mcp-server
cd kite-mcp-server

Configuration

Create a `.env` file with your Kite Connect credentials:

KITE_API_KEY=your_api_key
KITE_API_SECRET=your_api_secret
APP_MODE=http
APP_PORT=8080
APP_HOST=localhost
PUBLIC_BASE_URL=http://localhost:8080

You can also use the provided `justfile` to initialize the config.

just init-env

Running the Server

# Build and run
go build -o kite-mcp-server
./kite-mcp-server

# Or run directly
go run main.go

The server will start and serve a status page at `http://localhost:8080/`

Client Integration

Setup Guide

• Claude Desktop (Hosted Mode) - Recommended
• Claude Desktop (HTTP Mode) - Recommended
• Claude Desktop (SSE Mode)
• Claude Desktop (stdio Mode)
• Other MCP Clients

Claude Desktop (Hosted Mode)

For the hosted version, add to your Claude Desktop configuration (`~/.config/Claude/claude_desktop_config.json`):

{
  "mcpServers": {
    "kite": {
      "command": "npx",
      "args": ["mcp-remote", "https://mcp.kite.trade/mcp"]
    }
  }
}

Claude Desktop (HTTP Mode)

Add to your Claude Desktop configuration (`~/.config/Claude/claude_desktop_config.json`):

{
  "mcpServers": {
    "kite": {
      "command": "npx",
      "args": ["mcp-remote", "http://localhost:8080/mcp", "--allow-http"],
      "env": {
        "APP_MODE": "http",
        "KITE_API_KEY": "your_api_key",
        "KITE_API_SECRET": "your_api_secret"
      }
    }
  }
}

Claude Desktop (SSE Mode)

Add to your Claude Desktop configuration (`~/.config/Claude/claude_desktop_config.json`):

{
  "mcpServers": {
    "kite": {
      "command": "npx",
      "args": ["mcp-remote", "http://localhost:8080/sse", "--allow-http"],
      "env": {
        "APP_MODE": "sse",
        "KITE_API_KEY": "your_api_key",
        "KITE_API_SECRET": "your_api_secret"
      }
    }
  }
}

Claude Desktop (stdio Mode)

For self-hosted installations, you must first build the binary:

go build -o kite-mcp-server

Then add to your Claude Desktop configuration (`~/.config/Claude/claude_desktop_config.json`):

{
  "mcpServers": {
    "kite": {
      "command": "/full/path/to/your/kite-mcp-server",
      "env": {
        "APP_MODE": "stdio",
        "KITE_API_KEY": "your_api_key",
        "KITE_API_SECRET": "your_api_secret"
      }
    }
  }
}

Important: Use the full absolute path to your built binary. For example:

• `/home/username/kite-mcp-server/kite-mcp-server` (Linux)
• `/Users/username/kite-mcp-server/kite-mcp-server` (macOS)
• `C:\Users\username\kite-mcp-server\kite-mcp-server.exe` (Windows)

Other MCP Clients

For other MCP-compatible clients, use the hosted endpoint `https://mcp.kite.trade/mcp` with mcp-remote or configure your client to connect directly to the HTTP endpoint.

API Coverage

This server implements the majority of Kite Connect API endpoints and also provides additional tools.

Development

Development Environment

This project includes a Nix flake for consistent development environments:

# Enter development shell
nix develop

# Or with direnv
direnv allow

Using Just Commands

Install Just for convenient development commands:

just build      # Build the project
just run        # Run the server
just test       # Run tests
just lint       # Format and lint code
just coverage   # Generate coverage report

Running Tests

Requirements:

• Go 1.23+ with `GOEXPERIMENT=synctest` (required for timing-dependent tests)

# Run all tests
just test

# With coverage
just coverage

# With race detector
just test-race

# Direct go command (if you prefer)
CGO_ENABLED=0 GOEXPERIMENT=synctest go test -v ./...

Synctest Integration

This project requires Go's `synctest` package for time-dependent tests (session expiry, clock skew tolerance). All timing tests use `synctest.Run()` for:

• Fast execution: Time-dependent tests complete in milliseconds instead of minutes
• Deterministic timing: No flaky timing-based test failures
• Controlled time: Tests can advance time without actual delays

The justfile automatically includes `GOEXPERIMENT=synctest` in all test commands.

Configuration Options

Note: In production, we use hybrid mode which supports both `/sse` and `/mcp` endpoints, making both HTTP and SSE protocols available for different client needs.

Tool Exclusion

You can exclude specific tools by setting the `EXCLUDED_TOOLS` environment variable with a comma-separated list of tool names. This is useful for creating read-only instances.

Example:

EXCLUDED_TOOLS=place_order,modify_order,cancel_order

The hosted version at `mcp.kite.trade` excludes potentially destructive trading operations for security. For accessing the other operations you can generate your own API keys and run the server locally.
