What is this?

Tapetide MCP Server is a Model Context Protocol server that connects AI assistants to real-time Indian stock market data. It covers all ~8,200 stocks listed on NSE and BSE — from large-cap Nifty 50 to SME stocks.

Ask your AI to look up any stock, run a screener with 326 fundamental filters or real-time technical indicators, pull quarterly financials, check analyst consensus ratings, track your portfolio P&L, monitor FII/DII institutional flows, or get today's bulk deals — all through natural language.

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

Quick Start

Option 1: Remote MCP (No install — claude.ai, chatgpt.com, Grok, Gemini)

Add this URL directly in your AI chat app:

Code

https://mcp.tapetide.com/mcp

Authentication happens automatically via Google OAuth. 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:

Get a free token at tapetide.com/settings/tokens
Add to your MCP config:

config.json

{
  "mcpServers": {
    "tapetide": {
      "type": "url",
      "url": "https://mcp.tapetide.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN_HERE"
      }
    }
  }
}

Option 3: Local MCP via npm (Claude Code, Codex, Cursor, Windsurf, VS Code, Gemini CLI, Kiro, OpenCode)

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

Get a free token at tapetide.com/settings/tokens
Add to your MCP config:

config.json

{
  "mcpServers": {
    "tapetide": {
      "command": "npx",
      "args": ["-y", "tapetide-mcp"],
      "env": {
        "TAPETIDE_TOKEN": "your_token_here"
      }
    }
  }
}

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

How It Works

Code

┌─────────────────┐     stdio (JSON-RPC)     ┌──────────────────┐     HTTPS      ┌─────────────────────┐
│  AI Assistant   │ ◄──────────────────────► │  tapetide-mcp    │ ◄────────────► │  mcp.tapetide.com   │
│  (Claude, etc.) │                           │  (npm package)   │                │  (Cloudflare Worker) │
└─────────────────┘                           └──────────────────┘                └─────────────────────┘

The npm package is a lightweight stdio bridge with zero runtime dependencies. It:

Reads JSON-RPC from stdin, forwards to the remote Tapetide MCP server, writes responses to stdout
Auto-detects framing: Content-Length (VS Code, Claude Desktop) or newline-delimited JSON (Kiro, Claude Code)
Exchanges your refresh token for a 1-hour HMAC access token, auto-refreshes before expiry
Handles SSE responses from the remote server
Identifies your MCP client to the remote via User-Agent, and echoes the negotiated protocol version
Warns on stderr when the server rate-limits a call, naming the retry delay

All 52 tools and their logic run on the remote server — the npm package is just the transport layer. Because it forwards JSON-RPC verbatim, tools shipped on the remote are available immediately without upgrading this package.

Authentication

Method	How it works	Best for
Google OAuth	Browser sign-in, automatic token refresh	AI chat apps (Claude.ai, ChatGPT, Grok, Gemini)
Personal Token (remote)	`Authorization: Bearer tpt_rt_...` header	Code editors with URL-based MCP (VS Code, Kiro, Zed)
Personal Token (local)	`TAPETIDE_TOKEN` env var via npx	stdio MCP clients (Cursor, Windsurf, Claude Desktop, Codex)

Generate a free personal token at tapetide.com/settings/tokens. Works for both remote and local MCP.

Tip: ask your assistant to call read_me first. It returns the full in-session guide — every tool by category, usage patterns, and the rules the server expects clients to follow.

Environment Variables

Variable	Required	Default	Description
`TAPETIDE_TOKEN`	Yes (local)	—	Personal API token from tapetide.com/settings/tokens
`TAPETIDE_MCP_URL`	No	`https://mcp.tapetide.com`	Override remote server URL
`TAPETIDE_DEBUG`	No	`0`	Set to `1` for debug logging to stderr

Rate Limits

Limits are per Tapetide account and identical across all three access methods (OAuth, remote token, and this npm bridge) — they follow your plan, not your transport.

Scope	Free plan	Paid plans
Per day	50 tool calls	Per your plan
Per calendar month	1,000 tool calls	Per your plan (unlimited on enterprise)
Burst	60 tool calls per minute	60 tool calls per minute

Only successful tool calls consume quota. Protocol traffic (initialize, tools/list) and burst-denied calls are free. Daily and monthly windows reset on IST boundaries.

When a limit is hit, the server replies with a normal JSON-RPC result carrying isError: true and a message naming the binding cap and its reset time, so your assistant relays it instead of retrying. Responses carry X-RateLimit-Reset, and denials add Retry-After. The numeric quota itself is not exposed as a header — check current usage at tapetide.com/settings/tokens.

Troubleshooting

Problem	Solution
`TAPETIDE_TOKEN environment variable is required`	Add your token to the `env` section of your MCP config
`Token refresh failed (401)`	Token expired. Generate a new one at tapetide.com/settings/tokens
`Rate limit exceeded`	Wait for reset (shown in error) or check usage at tapetide.com/settings/tokens
Server not responding	Ensure Node.js 18+ is installed (`node --version`)
Slow first request	Normal — pre-authenticates on startup. Subsequent requests are fast
Network errors	Check internet. The bridge needs to reach `mcp.tapetide.com`

Set TAPETIDE_DEBUG=1 for detailed logging to stderr.

Issues and pull requests are welcome. For bugs, include the error message and your MCP client name/version.
