Claude MCP server for Tradier Sandbox API options chain endpoint and historical prices endpoint.

An MCP server implementation for providing access to the Tradier Sandbox API within Claude Desktop.

Overview

This Model Context Protocol (MCP) server enables AI assistants and applications to:

• Get options chain data for a specific stock and expiration date
• Filter for only call or put options, or both as default
• Filter for a percentage range around the current price
• Automatically filters for significant strikes to limit context size
• Get historical prices for a specific stock or option contract in a given time range

Please note:

• Requires Tradier account and sandbox API access token
• Sandbox API market data is delayed by 15 minutes
• Intended for informational purposes only

Users can run queries using natural language.

Installation

Installing this might be tricky if you're not familiar with Node.js and the MCP protocol.

1. Install Node.js

2. Clone this repository to a folder on your local machine

3. The server is already built so you can skip the build step.

Extra Steps

If you want to make changes to the server you can do so by editing the src/index.ts file.

• Run npm install to install dependencies
• Run npm run build to build the server
• Quit and restart Claude Desktop after making changes

Connecting with Claude Desktop

1. Open your Claude Desktop configuration at:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add the server configuration:

{
    "mcpServers": {
        "options-chain": {
            "command": "node",
            "args": [
                "/Full/Route/to/Folder/options-chain/build/index.js"
            ],
            "env": {
                "token": "your_sandbox_api_token_here"
            }
        }
    }
}

3. Close/Quit then restart Claude Desktop

Once you restart you should see a small hammer icon in the lower right corner of the textbox. If you hover over the icon you'll see the number of MCP tools available.

Troubleshooting

If you get errors when running the server you may need to provide the full path to the node command. For example, on macOS: /usr/local/bin/node
