## Quick Start 
 
### Install 
 
```bash 
pip install yfinance-market-mcp 
``` 
 
Or run directly without installing (requires [uv](https://docs.astral.sh/uv/)): 
 
```bash 
uvx yfinance-market-mcp 
``` 
 
For local development (editable install): 
 
```bash 
git clone https://github.com/hachecito/yfinance-market-mcp.git 
cd yfinance-market-mcp 
pip install -e . 
``` 
 
### Verify Installation 
 
```bash 
yfinance-mcp --help 
``` 
 
If the command is found, the server is ready.

## Usage 
 
### With Claude Code 
 
Create a `.mcp.json` file in your project root: 
 
Using pip: 
```json 
{ 
  "mcpServers": { 
    "yfinance": { 
      "command": "yfinance-mcp" 
    } 
  } 
} 
``` 
 
Using uvx (no install needed): 
```json 
{ 
  "mcpServers": { 
    "yfinance": { 
      "command": "uvx", 
      "args": ["yfinance-market-mcp"] 
    } 
  } 
} 
``` 
 
Then restart Claude Code. The 30 tools will be available automatically — just ask Claude about any stock, options chain, or market news. 
 
### With Claude Desktop 
 
Edit `%APPDATA%\Claude\claude_desktop_config.json` (Windows) or `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS): 
 
Using pip: 
```json 
{ 
  "mcpServers": { 
    "yfinance": { 
      "command": "yfinance-mcp" 
    } 
  } 
} 
``` 
 
Using uvx: 
```json 
{ 
  "mcpServers": { 
    "yfinance": { 
      "command": "uvx", 
      "args": ["yfinance-market-mcp"] 
    } 
  } 
} 
``` 
 
Restart Claude Desktop. Done. 
 
### With Any MCP Client 
 
The server uses **stdio** transport. Launch it with: 
 
```bash 
yfinance-mcp 
# or 
uvx yfinance-market-mcp 
``` 
 
Connect your MCP client to stdin/stdout of that process.
