Portfolio Signals MCP

An MCP server that gives any AI coding agent (Claude Code, Cursor, Claude Desktop, etc.) real-time stock quotes and computed technical-analysis signals — RSI, MACD crossovers, golden/death crosses, and whole-portfolio weekly digests. Indicators are calculated in code, not by the LLM, so the numbers are right.

Data source: Yahoo Finance via yfinance — free, no API key required.

mcp-name: io.github.KhizarShabir1/portfolio-signals

Tools

Design principle: tools return measurements and standard threshold classifications (RSI 70/30 zones, golden/death cross, MACD vs signal line) — never directional opinions or narrative summaries. Interpretation is the agent's job; determinism is the server's.

Quick start

No install needed if you have uv:

uvx portfolio-signals-mcp

Claude Code

claude mcp add portfolio-signals -- uvx portfolio-signals-mcp

Then ask Claude things like:

• "What's the RSI and MACD on NVDA right now?"
• "Compare AAPL, MSFT and VOO over 6 months."
• "Give me a weekly digest for my portfolio: AAPL, NVDA, VOO, TSLA."

Cursor

Settings → Tools & MCP → Add a Custom MCP Server:

{
  "mcpServers": {
    "portfolio-signals": {
      "command": "uvx",
      "args": ["portfolio-signals-mcp"]
    }
  }
}

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "portfolio-signals": {
      "command": "uvx",
      "args": ["portfolio-signals-mcp"]
    }
  }
}

Remote (HTTP)

No local install — connects directly to the hosted instance:

claude mcp add --transport http portfolio-signals https://portfolio-signals-mcp.fly.dev/mcp

From source

git clone https://github.com/KhizarShabir1/portfolio-signals-mcp
cd portfolio-signals-mcp
pip install -e .
portfolio-signals-mcp           # stdio
portfolio-signals-mcp --http    # streamable HTTP on :8000 (PORT env to change)
