finstack-mcp 0.3.4

Open-source MCP server for Indian (NSE/BSE) + Global financial data with built-in AI analytics

FinStack MCP

FinStack MCP is an India-first financial data and research engine for MCP clients. It gives Claude, Cursor, ChatGPT, and other MCP-compatible tools a structured interface for NSE/BSE market data, global market coverage, fundamentals, analytics, and watchlist-ready research workflows.

Built and maintained by Arunodayya B S (@SpawnAgent) — open source, MIT licensed.

The repo is public on purpose. It is the open-source engine, trust layer, and distribution channel for the broader FinStack product line.

Overview

FinStack MCP is designed around a simple product split:

• finstack-mcp is the open-source MCP engine
• FinStack Brief is the paid delivery layer built on top of it

That means this repo focuses on the part that should be public and reusable:

• financial data access for Indian and global markets
• structured tools that work inside MCP clients
• reusable analytics for research workflows
• a base layer for future brief, alert, and dashboard products

Why This Exists

Most finance MCP servers are either too generic, too thin, or too dependent on API-key-heavy setups. FinStack MCP is meant to be more practical:

• India-first coverage instead of treating NSE/BSE as an afterthought
• broad enough to be useful on day one
• simple enough to install with one package
• compatible with local MCP workflows before any hosted product exists

• reusable engine for future products

The paid wedge currently being built on top of this engine is the Indian market daily brief.

Data Sources

Source	Coverage	API key required
yfinance	NSE, BSE, US equities, crypto, forex, earnings	No

SEC EDGAR	US filings and company submission data	No

Daily Brief Direction

The first commercial layer on top of FinStack MCP is not "generic pro access." It is a repeatable workflow:

1. pull Indian market state
2. enrich it with watchlist context
3. compose a structured brief
4. deliver it through email, Telegram, WhatsApp, or a hosted dashboard

That is the bridge from open-source distribution to paid recurring value.
