Schwab MCP

Schwab Model Context Protocol Server

The Schwab Model Context Protocol (MCP) Server connects your Schwab account to LLM-based applications (like Claude Desktop or other MCP clients), allowing them to retrieve market data, check account status, and (optionally) place orders under your supervision.

Features

• Market Data: Real-time quotes, price history, option chains, and market movers.
• Account Management: View balances, positions, and transactions.
• Trading: comprehensive support for equities and options, including complex strategies (OCO, Bracket).
• Safety First: Critical actions (like trading) are gated behind a Discord approval workflow by default.
• LLM Integration: Designed specifically for Agentic AI workflows.

Quick Start

Prerequisites

• Python 3.10 or higher
• uv (recommended) or pip
• A Schwab Developer App Key and Secret (from the Schwab Developer Portal)

Installation

For most users, installing via uv tool or pip is easiest:

# Using uv (recommended for isolation)
uv tool install git+https://github.com/jkoelker/schwab-mcp.git

# Using pip
pip install git+https://github.com/jkoelker/schwab-mcp.git

Authentication

Before running the server, you must authenticate with Schwab to generate a token file.

# If installed via uv tool
schwab-mcp auth --client-id YOUR_KEY --client-secret YOUR_SECRET --callback-url https://127.0.0.1:8182

# If running from source
uv run schwab-mcp auth --client-id YOUR_KEY --client-secret YOUR_SECRET --callback-url https://127.0.0.1:8182

This will open a browser window for you to log in to Schwab. Once complete, a token will be saved to ~/.local/share/schwab-mcp/token.yaml.

Running the Server

Start the MCP server to expose the tools to your MCP client.

# Basic Read-Only Mode (Safest)
schwab-mcp server --client-id YOUR_KEY --client-secret YOUR_SECRET

# Streamable HTTP (for reverse proxies / remote MCP connectors)
schwab-mcp server --client-id YOUR_KEY --client-secret YOUR_SECRET \
  --http --host 127.0.0.1 --port 8000

# With Trading Enabled (Requires Discord Approval)
schwab-mcp server \
  --client-id YOUR_KEY \
  --client-secret YOUR_SECRET \
  --discord-token BOT_TOKEN \
  --discord-channel-id CHANNEL_ID \
  --discord-approver YOUR_USER_ID

Default transport is stdio (Claude Desktop and most local MCP clients). Use --http for FastMCP streamable-http when fronting the server with a gateway or remote connector (MCP endpoint is /mcp on the bound host:port).

Note: For trading capabilities, you must set up a Discord bot for approvals. See Discord Setup Guide.

Configuration

You can configure the server using CLI flags or Environment Variables.

Flag	Env Variable	Description
--client-id	SCHWAB_CLIENT_ID	Required. Schwab App Key.
--client-secret	SCHWAB_CLIENT_SECRET	Required. Schwab App Secret.
--callback-url	SCHWAB_CALLBACK_URL	Redirect URL (default: https://127.0.0.1:8182).
--token-path	N/A	Path to save/load token (default: ~/.local/share/...).
--http	N/A	Use streamable-http transport instead of stdio.
--host	MCP_HOST	Bind address when using --http (default: 127.0.0.1).
--port	MCP_PORT	Bind port when using --http (default: 8000).
--jesus-take-the-wheel	N/A	DANGER. Bypasses Discord approval for trades.
--no-technical-tools	N/A	Disables technical analysis tools (SMA, RSI, etc.).
--json	N/A	Returns JSON instead of formatted text (useful for some agents). Null/empty fields are stripped to reduce token usage.

Container Usage

A Docker/Podman image is available at ghcr.io/jkoelker/schwab-mcp.

podman run --rm -it \
  --env SCHWAB_CLIENT_ID=... \
  --env SCHWAB_CLIENT_SECRET=... \
  -v ~/.local/share/schwab-mcp:/schwab-mcp \
  ghcr.io/jkoelker/schwab-mcp:latest server --token-path /schwab-mcp/token.yaml

Available Tools

The server provides a rich set of tools for LLMs.

📊 Market Data

Tool	Description
get_quotes	Real-time quotes for symbols.
get_market_hours	Market open/close times.
get_movers	Top gainers/losers for an index.
get_option_chain	Standard option chain data.
get_price_history_*	Historical candles (minute, day, week).

💼 Account Info

Tool	Description
get_accounts	List linked accounts (pass include_positions=True for holdings).
get_account	Balances for one account by hash (pass include_positions=True for holdings).
get_transactions	History of trades and transfers.
get_orders	Status of open and filled orders.

💸 Trading (Requires Approval)

Placing an order is two steps: preview it, then place it by ID. Every preview_* tool builds the order and calls Schwab's preview API to return the projected order details plus a preview_id; place_previewed_order then submits that exact previewed order — no re-derivation from parameters, so the LLM can't hallucinate a different order than what was reviewed.

Tool	Description
preview_equity_order	Preview a stock/ETF buy or sell.
preview_option_order	Preview an option contract buy or sell.
preview_bracket_order	Preview an entry + take-profit + stop-loss order. Stop-loss exit type defaults to STOP; pass loss_type (STOP, STOP_LIMIT, or LIMIT) for a different exit, plus loss_limit_price when loss_type is STOP_LIMIT; the response's resolved_leg_types shows what was actually built.
place_previewed_order	Place the exact order returned by a preview_* call, by preview_id. Requires approval.
cancel_order	Cancel an open order.
