Vibe Trading is here!

Official Composer Model Context Protocol (MCP) server that allows MCP-enabled LLMs like Cursor and Claude to validate investment ideas via backtests and even trade multiple strategies (called "symphonies") in parallel to compare their live performance.

## Features - **Create automated investing strategies** - Use indicators like Relative Strength Index (RSI), Moving Average (MA), and Exponential Moving Average (EMA) with a diverse range of equity and crypto offerings to build your ideal portfolio. - Don't just make one-off trades. Composer symphonies constantly monitor the market and rebalance accordingly. - Try asking: "_Build me a crypto strategy with a maximum drawdown of 30% or less._" - **Backtest your ideas** - Our Backtesting API provides a fast feedback loop for AI to iterate and validate its hypotheses. - Try asking: "_Compare the strategy's performance against the S&P 500. Plot the results._" - **Find a strategy tailored for you** - Provide your criteria to the AI and it will search through our [database](https://www.composer.trade/symphony) of 1000+ strategies to find one that suits your needs. - Try asking: "_Find me a strategy with better risk-reward characteristics than Bitcoin._" - **Monitor performance** - View performance statistics for your overall account as well as for individual symphonies. - Try asking: "_Identify my best-performing symphonies. Analyze why they are working._" - **Control your investments** (requires [Composer subscription](https://www.composer.trade/pricing)) - Ask AI to analyze your investments and adjust your exposure accordingly! - Try asking: "_Research the latest trends and news. Analyze my symphonies and determine whether I should increase / decrease my investments._" For more ideas, check out our collection of [Awesome Prompts](https://github.com/invest-composer/composer-trade-mcp/blob/main/AWESOME_PROMPTS.md)! # Installation This section will get you started with creating symphonies and backtesting them. Use the links below to jump to the instructions for your preferred LLM client: - [Claude Desktop + iOS](https://github.com/invest-composer/composer-trade-mcp?tab=readme-ov-file#quickstart-with-claude-desktop-and-claude-ios) - [Claude Code](https://github.com/invest-composer/composer-trade-mcp?tab=readme-ov-file#quickstart-with-claude-code) - [Cursor](https://github.com/invest-composer/composer-trade-mcp#quickstart-with-cursor) - [n8n](https://github.com/invest-composer/composer-trade-mcp#quickstart-with-n8n) - [Other LLMs](https://github.com/invest-composer/composer-trade-mcp#manual-install-for-other-llm-clients) ## Quickstart with Claude Desktop and Claude iOS **To use the Composer MCP, you’ll need the Claude Pro or Max [plan](https://www.anthropic.com/pricing).** https://github.com/user-attachments/assets/f560c127-4c87-4932-b515-6cad962c8ddc 1.

Get your [API Key](https://github.com/invest-composer/composer-trade-mcp?tab=readme-ov-file#getting-your-api-key) 1. Base64 Encode your key and secret separated with `:` - Example: `MY_KEY:MY_SECRET` becomes `TVlfS0VZOk1ZX1NFQ1JFVA==` after Base64 encoding 1. Make sure your n8n version is at least `1.104.0` - Learn how to check and update your n8n version [here](https://docs.n8n.io/manage-cloud/update-cloud-version/). 1. Add "MCP Client Tool" as a tool for your agent 1. Input the following fields: - Endpoint: `https://mcp.composer.trade/mcp/` - Server Transport: `HTTP Streamable` - Authentication: `Header Auth` - Create a new credential and enter the following in the Connection tab: - Name: `Authorization` - Value: `Basic REPLACE_WITH_BASE64_ENCODED_KEY_AND_SECRET` (Use your Base64 encoded key and secret here) 1. Select which tools you want to allow your agent to use. - We recommend **excluding** the following tools that can modify your account: - `save_symphony` - Save a symphony to the user's account - `copy_symphony` - Copy an existing symphony to the user's account - `update_saved_symphony` - Update a saved symphony - `invest_in_symphony` - Invest in a symphony for a specific account - `withdraw_from_symphony` - Withdraw money from a symphony for a specific account - `cancel_invest_or_withdraw` - Cancel an invest or withdraw request that has not been processed yet - `skip_automated_rebalance_for_symphony` - Skip automated rebalance for a symphony in a specific account - `go_to_cash_for_symphony` - Immediately sell all assets in a symphony - `liquidate_symphony` - Immediately sell all assets in a symphony (or queue for market open if outside of market hours) - `rebalance_symphony_now` - Rebalance a symphony NOW instead of waiting for the next automated rebalance - `execute_single_trade` - Execute a single order for a specific symbol like you would in a traditional brokerage account - `cancel_single_trade` - Cancel a request for a single trade that has not executed yet ## Manual install for other LLM clients To install for any other MCP-enabled LLM, you can add the following to your MCP configuration JSON: ``` { "mcpServers": { "composer": { "url": "https://ai.composer.trade/mcp" } } } ``` ‼️ **NOTE: ChatGPT does not support custom MCP servers unless you have the Pro Plan ($200/mo). They also do not support MCP servers with more than two tools.** ‼️ ## Getting your API Key An API key will be necessary to interact with your Composer account. For example, saving a Composer Symphony for later or viewing statistics about your portfolio. Trading a symphony will require a paid subscription, although you can always liquidate a position regardless of your subscription status. Composer also includes a 14-day free trial so you can try without any commitment. Get your API key from [Composer](https://app.composer.trade) by following these steps: 1. If you haven't already done so, [create an account](https://app.composer.trade/register). 1. Open your "Accounts & Funding" page ![CleanShot 2025-06-25 at 14 28 12@2x](https://github.com/user-attachments/assets/7821f9f8-07ad-4fa9-87e0-24b29e6bbd87) 1. Request an API key

1. Save your API key and secret

## Available tools Once your LLM is connected to the Composer MCP Server, it will have access to the following tools: - `create_symphony` - Define an automated strategy using Composer's system. - `backtest_symphony` - Backtest a symphony that was created with `create_symphony` - `search_symphonies` - Search through a database of existing Composer symphonies. - `backtest_symphony_by_id` - Backtest an existing symphony given its ID - `save_symphony` - Save a symphony to the user's account - `copy_symphony` - Copy an existing symphony to the user's account - `update_saved_symphony` - Update a saved symphony - `list_accounts` - List all brokerage accounts available to the Composer user - `get_account_holdings` - Get the holdings of a brokerage account - `get_aggregate_portfolio_stats` - Get the aggregate portfolio statistics of a brokerage account - `get_aggregate_symphony_stats` - Get stats for every symphony in a brokerage account - `get_symphony_daily_performance` - Get daily performance for a specific symphony in a brokerage account - `get_portfolio_daily_performance` - Get the daily performance for a brokerage account - `get_saved_symphony` - Get the definition about an existing symphony given its ID. - `get_market_hours` - Get market hours for the next week - `get_options_chain` - Get options chain data for a specific underlying asset symbol with filtering and pagination - `get_options_contract` - Get detailed information about a specific options contract including greeks, volume, and pricing - `get_options_calendar` - Get the list of distinct contract expiration dates available for a symbol - `invest_in_symphony` - Invest in a symphony for a specific account - `withdraw_from_symphony` - Withdraw money from a symphony for a specific account - `cancel_invest_or_withdraw` - Cancel an invest or withdraw request that has not been processed yet - `skip_automated_rebalance_for_symphony` - Skip automated rebalance for a symphony in a specific account - `go_to_cash_for_symphony` - Immediately sell all assets in a symphony - `liquidate_symphony` - Immediately sell all assets in a symphony (or queue for market open if outside of market hours) - `preview_rebalance_for_user` - Perform a dry run of rebalancing across all accounts to see what trades would be recommended - `preview_rebalance_for_symphony` - Perform a dry run of rebalancing for a specific symphony to see what trades would be recommended - `rebalance_symphony_now` - Rebalance a symphony NOW instead of waiting for the next automated rebalance - `execute_single_trade` - Execute a single order for a specific symbol like you would in a traditional brokerage account - `cancel_single_trade` - Cancel a request for a single trade that has not executed yet ## Recommendations We recommend the following for the best experience with Composer: - Use Claude Opus 4 instead of Sonnet. Opus is much better at tool use. - Turn on Claude's Research mode if you need the latest financial data and news. - Tools that execute trades or affect your funds should only be allowed once. Do not set them to "Always Allow". - The following tools should be handled with care: `invest_in_symphony`, `withdraw_from_symphony`, `skip_automated_rebalance_for_symphony`, `go_to_cash_for_symphony`, `liquidate_symphony`, `rebalance_symphony_now`, `execute_single_trade` ## Troubleshooting Logs when running with Claude Desktop can be found at: - **Windows**: `%APPDATA%\Claude\logs\mcp-server-composer.log` - **macOS**: `~/Library/Logs/Claude/mcp-server-composer.log` --- _Please review the [API & MCP Server Disclosure](https://storage.googleapis.com/www.investcomposer.com/docs/COM%20sh%20-%20API%20%26%20MCP%20Server%20Disclosure.pdf) before using the API_
