Schwab Model Context Protocol (MCP) for the Schwab API

Schwab Model Context Protocol Server

This is a server that implements the Model Context Protocol (MCP) for the Schwab API using schwab-py and the MCP python-sdk.

Features

• Expose Schwab API functionality through Model Context Protocol
• Get account information and positions
• Retrieve stock quotes and price history
• Get market information and movers
• Fetch option chains and expiration data
• Access order and transaction history
• Modify account state with special tools (requires --jesus-take-the-wheel flag)
• Designed to integrate with Large Language Models (LLMs)

Installation

# Install with all dependencies
uv add -e .

# Install development dependencies
uv add -e .[dev]

Usage

Authentication

The first step is to authenticate with the Schwab API and generate a token:

# Authenticate and generate a token
uv run schwab-mcp auth --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET --callback-url YOUR_CALLBACK_URL

You can set these credentials through environment variables to avoid typing them each time:

• SCHWAB_CLIENT_ID
• SCHWAB_CLIENT_SECRET
• SCHWAB_CALLBACK_URL (defaults to https://127.0.0.1:8182)

By default, the token is saved to ~/.local/share/schwab-mcp/token.yaml (platform-specific). You can specify a different path:

uv run schwab-mcp auth --token-path /path/to/token.yaml

Both yaml and json token formats are supported and will be inferred from the file extension.

Running the Server

After authentication, you can run the server:

# Run the server with default token path
uv run schwab-mcp server --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET --callback-url YOUR_CALLBACK_URL

# Run with a custom token path
uv run schwab-mcp server --token-path /path/to/token.json --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET --callback-url YOUR_CALLBACK_URL

# Run with account modification tools enabled
uv run schwab-mcp server --jesus-take-the-wheel --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET --callback-url YOUR_CALLBACK_URL

Token age is validated - if older than 5 days, you will be prompted to re-authenticate.

WARNING: Using the --jesus-take-the-wheel flag enables tools that can modify your account state. Use with caution as this allows LLMs to cancel orders and potentially perform other actions that change account state.
