Why is this implemented in Go?

Go provides strong performance characteristics and easy deployment as a single binary, making it a practical choice for an MCP server that handles real-time market data and brokerage communication.

Do I need a Zerodha Kite Connect API subscription?

Yes. The server connects through Zerodha's Kite Connect API, which requires a separate API subscription in addition to your regular Zerodha trading account.

Does this support both NSE and BSE?

Zerodha provides access to both NSE and BSE through the Kite Connect API, and this server should expose data from whichever exchanges your Zerodha account supports.

Zerodha MCP (Go) | CLI Trader

Zerodha MCP (Go) is a Go-based MCP server that connects agents to Zerodha, one of India’s largest discount brokerages. It provides structured access to Indian stock market data and trading operations through the MCP protocol, enabling agent-assisted workflows for traders on the Indian equity markets. The Go implementation offers efficient performance and straightforward deployment characteristics.

The server interfaces with Zerodha’s Kite Connect API to retrieve market data, manage orders, and access account information. This allows MCP-compatible agents to work with live Indian market data in a typed, structured format — useful for tasks like screening NSE or BSE stocks, checking portfolio positions, or preparing trade orders. The MCP layer abstracts the Kite Connect API complexity, so agents interact with clean tool definitions rather than raw HTTP endpoints.

This server is well suited for Indian market traders who use Zerodha and want to integrate their brokerage into an agent-driven workflow. The Go implementation is easy to build and run as a standalone binary, which simplifies deployment compared to runtime-dependent alternatives. As always, start with read-only operations and add execution gates before enabling live order placement.
