A Model Context Protocol server for interacting with TastyTrade brokerage accounts. This server enables Large Language Models to monitor portfolios, analyze positions, and execute trades through the TastyTrade platform.

curl -LsSf https://astral.sh/uv/install.sh | shWe will use uvx to directly run tasty-agent:
uvx tasty-agentThe server requires TastyTrade credentials. For security, this is set up via command line and stored in your system's keyring (Keychain on macOS, Windows Credential Manager on Windows, or similar secure storage on other platforms):
uvx tasty-agent setupAlternatively, you can set the following environment variables:
TASTYTRADE_USERNAME: Your Tastytrade usernameTASTYTRADE_PASSWORD: Your Tastytrade passwordTASTYTRADE_ACCOUNT_ID: Your Tastytrade account number (optional if you only have one account)
If credentials are found in both the keyring and environment variables, the keyring values will take precedence.

Add this to your claude_desktop_config.json:
{
"mcpServers": {
"tastytrade": {
"command": "path/to/uvx/command/uvx",
"args": ["tasty-agent"]
}
}
}Important: Scheduled trades will only execute while Claude Desktop is running. When Claude Desktop is closed, the server shuts down and trades are not executed.
You can use the MCP inspector to debug the server:
npx @modelcontextprotocol/inspector uvx tasty-agentFor logs, check:
- macOS:
~/Library/Logs/Claude/mcp*.log - Windows:
%APPDATA%\Claude\logs\mcp*.log
For local development testing:
- Use the MCP inspector (see Debugging)
- Test using Claude Desktop with this configuration:
{
"mcpServers": {
"tastytrade": {
"command": "path/to/uv/command/uv",
"args": [
"--directory",
"path/to/tasty-agent",
"run",
"tasty-agent"
]
}
