Model Context Protocol

AltraOne MCP Server

Q: What is the AltraOne MCP server?

It's a remote Model Context Protocol server that exposes AltraOne's momentum data (Altra Score, Altra Market, and Altra Sector) as tools any MCP-compatible AI client can call, instead of the model guessing at market conditions.

Q: Which AI clients can connect to the AltraOne MCP server?

Any MCP client that supports the Streamable HTTP transport with custom headers, including Claude Desktop (via the mcp-remote bridge), Cursor, and Windsurf.

Q: Which markets and stocks does the AltraOne MCP server cover?

About 1,000 stocks in total, across the S&P 500 (US), NSE F&O stocks (India), and TSX (Canada).

Q: Is AltraOne MCP data live or end-of-day?

Data is calculated end-of-day (EOD), not intraday.

Connect Claude Desktop, Cursor, Windsurf, or any MCP-compatible client to AltraOne's momentum scoring. Ask your AI assistant about market regime, sector strength, or a single stock, and get real Altra Score, Altra Market, and Altra Sector data back, not a guess.

Connect your AI client

The MCP endpoint is https://mcp.altraone.com/ over Streamable HTTP. Every request needs an X-Altra-Key header set to your generated key.

Settings → Developer → Edit Config (claude_desktop_config.json)

Claude Desktop doesn't call custom-header remote MCP servers directly. Route through the mcp-remote bridge shown below. Restart Claude Desktop after saving.

{
  "mcpServers": {
    "altraone": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.altraone.com/",
        "--header",
        "X-Altra-Key:${ALTRA_API_KEY}"
      ],

        "ALTRA_API_KEY": "<your-api-key>"

Frequently Asked Questions

What is the AltraOne MCP server?

It's a remote Model Context Protocol server that exposes AltraOne's momentum data (Altra Score, Altra Market, and Altra Sector) as tools any MCP-compatible AI client can call. Instead of your AI assistant guessing at market conditions, it calls a tool and gets back real, EOD-calculated data for NSE, S&P 500, or TSX stocks.

Is it free?

Yes. Every API key gets 100 requests/day at no cost, with no credit card required. There's no paid tier yet.

Which AI clients can I connect it to?

Any MCP client that supports the Streamable HTTP transport with custom headers, including Claude Desktop (via the mcp-remote bridge), Cursor, and Windsurf, all covered in the setup section above.

Which markets and stocks are covered?

About 1,000 stocks in total, across the S&P 500 (US), NSE F&O stocks (India), and TSX (Canada): the same coverage as the AltraOne dashboard.

Is the data live or intraday?

No. Like the rest of AltraOne, MCP data is calculated end-of-day (EOD), not intraday. Check the market score's regime before treating it as a same-day signal.

How do I read the scores?

All three scores run 0–100. Above 60 generally means bullish, 40–60 is neutral/mixed, below 40 is bearish/cautious; exact zones differ slightly per score, shown above. See the full scoring criteria for how each score is calculated.

Can I recover a lost API key?

No. A key is shown once at generation and can't be retrieved afterward. There's no recovery flow; contact AltraOne support to reset it, since a signup already exists for that email.
