What is this?

InvestSights MCP is a Model Context Protocol server that connects AI assistants to research-grade Indian stock market data — the same engine that powers investsights.in.

Where most market servers stop at quotes and screens, InvestSights adds a research layer: forensic accounting scores (Piotroski F, Beneish M, Altman Z — with bank-aware CAMELS handling), multi-stage DCF + relative valuation, analyst consensus, shareholding patterns and curated news — for 6,000+ NSE/BSE companies.

Compatible with: Claude.ai, Claude Desktop, Claude Code, ChatGPT, Perplexity, Cursor, Windsurf, VS Code (Copilot), Kiro, Zed, Codex, Gemini, Grok, OpenCode, and any MCP-compatible client.

Quick Start

Option 1: Remote MCP with OAuth (claude.ai, ChatGPT, Perplexity, Grok)

Add this URL as a custom connector in your AI chat app:

https://investsights.in/api/v2/mcp-public/mcp

First use opens a browser — sign in with your InvestSights account (Google login) and approve access on the consent screen. No token needed.

Option 2: Remote MCP with Token (Claude Code, VS Code, Kiro, Zed)

For code editors that support URL-based MCP servers with custom headers:

1. Get a free key at investsights.in/account/connected-apps
2. Add to your MCP config:

{
  "mcpServers": {
    "investsights": {
      "type": "url",
      "url": "https://investsights.in/api/v2/mcp-public/mcp",
      "headers": {
        "Authorization": "Bearer usk_YOUR_KEY_HERE"
      }
    }
  }
}

URL-only client (no header support)? Use the key-in-URL form: https://investsights.in/api/v2/mcp-public/usk_YOUR_KEY_HERE/mcp

Option 3: Local MCP via npm (Cursor, Windsurf, Claude Desktop, Codex, Gemini CLI)

For stdio-based MCP clients. No cloning or building — runs via npx:

1. Get a free key at investsights.in/account/connected-apps
2. Add to your MCP config:

{
  "mcpServers": {
    "investsights": {
      "command": "npx",
      "args": ["-y", "investsights-mcp"],
      "env": {
        "INVESTSIGHTS_TOKEN": "usk_YOUR_KEY_HERE"
      }
    }
  }
}

Node.js 18+ required for the local option. Run node --version to check.

How It Works

┌─────────────────┐   stdio (JSON-RPC)   ┌───────────────────┐     HTTPS     ┌─────────────────────┐
│  AI Assistant   │ ◄──────────────────► │  investsights-mcp │ ◄───────────► │   investsights.in   │
│  (Claude, etc.) │                      │   (npm package)   │               │  (research backend) │
└─────────────────┘                      └───────────────────┘               └─────────────────────┘

The npm package is a lightweight stdio bridge (~250 lines, zero runtime dependencies). It:

• Reads JSON-RPC from stdin, forwards to the remote InvestSights MCP server, writes responses to stdout
• Auto-detects framing: Content-Length (VS Code, Claude Desktop) or newline-delimited JSON (Claude Code, Kiro)
• Authenticates every request with your personal key as a Bearer token
• Handles SSE responses from the remote server

All tools and their logic run on the remote server — the npm package is just the transport layer.

Authentication

Method	How it works	Best for
OAuth (Google sign-in)	Browser sign-in + consent screen, revocable anytime	AI chat apps (claude.ai, ChatGPT, Perplexity, Grok)
Personal key (remote)	Authorization: Bearer usk_... header, or key-in-URL	Code editors with URL-based MCP (VS Code, Kiro, Zed)
Personal key (local)	INVESTSIGHTS_TOKEN env var via npx	stdio MCP clients (Cursor, Windsurf, Claude Desktop)

Create and revoke keys anytime at investsights.in/account/connected-apps. Same free limits across every method.
