Translates conversational natural language requests into structured Alpaca API calls through a FastMCP-based protocol bridge. The server implements a request processing pipeline that parses LLM-generated text, maps it to 44+ registered tools, and executes corresponding Alpaca API operations with automatic parameter extraction and type coercion. This enables users to execute complex trading operations (orders, position management, data queries) by describing intent in plain English without learning API syntax.
Unique: Implements a FastMCP-based protocol bridge that directly exposes Alpaca's four API client types (TradingClient, StockHistoricalDataClient, OptionHistoricalDataClient, StockDataStream) as discrete MCP tools, enabling stateless request translation without intermediate abstraction layers or custom DSLs. The architecture maintains direct fidelity to Alpaca's native API semantics while providing natural language accessibility.
vs alternatives: Deeper API coverage than generic trading bots because it exposes Alpaca's full 44+ tool set directly through MCP rather than wrapping a subset in a custom language, and supports both paper and live trading modes with identical interfaces.
Provides environment-variable-controlled switching between paper trading (PAPER=True, default) and live trading (PAPER=False) modes that route all TradingClient operations to separate Alpaca API endpoints with distinct credential sets. The server initializes the appropriate API endpoint URL and authentication context at startup based on the PAPER flag, ensuring all subsequent order and position operations target the correct trading environment without code changes. This enables safe testing and development before risking real capital.
Unique: Implements mode isolation at the API client initialization layer (TradingClient constructor receives environment-specific endpoint URL), ensuring all downstream tool calls automatically target the correct trading environment without per-tool conditional logic. This design pattern prevents mode-switching bugs and keeps the tool implementation clean.
vs alternatives: Simpler and safer than tools that require per-operation mode checks because the routing decision is made once at server startup, reducing the surface area for accidental live trading and making the mode switch transparent to LLM clients.
Supports flexible credential and configuration management through multiple sources: .env files in the project directory, environment variables, and Claude Desktop config (claude_desktop_config.json). The server reads configuration at startup and initializes API clients with the appropriate credentials and endpoints. Supported configuration variables include ALPACA_API_KEY, ALPACA_SECRET_KEY, PAPER (trading mode), and optional proxy settings. This enables users to configure the server without modifying code and supports multiple deployment scenarios (local, Docker, cloud).
Unique: Supports three configuration sources (.env, environment variables, Claude Desktop config) with a clear precedence order, enabling flexible deployment across local development, Docker, and cloud environments. The server validates configuration at startup and fails fast if required credentials are missing.
vs alternatives: More flexible than tools with hardcoded configuration because it supports multiple sources and deployment scenarios, and more secure than tools that require credentials in code because it externalizes secrets to environment variables.
Provides a Dockerfile and Docker Compose configuration for containerizing the MCP server and deploying it in isolated environments. The Docker setup installs Python 3.10+, dependencies from requirements.txt, and runs the server as a container process. Docker environment variables can be passed at runtime to configure API credentials and trading mode. This enables deployment to cloud platforms (AWS, GCP, Azure), Kubernetes clusters, or local Docker environments without manual Python installation.
Unique: Provides both Dockerfile and Docker Compose configurations, enabling both single-container deployment and multi-service orchestration. The Docker setup is optimized for minimal image size and fast startup, using Python 3.10+ slim base image and layer caching.
vs alternatives: More deployment-ready than tools without Docker support because it includes production-ready container configurations, and more flexible than tools with only Docker Compose because it also supports standalone Dockerfile deployment.
Implements MCP tool discovery and schema documentation through the FastMCP framework, which automatically generates JSON schemas for all 44+ registered tools. Each tool includes a name, description, input schema (parameters with types and constraints), and output schema. MCP clients (Claude Desktop, Cursor, VSCode) use these schemas to discover available tools, validate parameters, and provide autocomplete suggestions. The server exposes tool metadata through the MCP protocol's tools/list and tools/describe endpoints.
Unique: Leverages FastMCP's automatic schema generation to produce JSON schemas for all tools without manual documentation, ensuring schemas stay in sync with implementation. The schemas include parameter types, constraints, and descriptions extracted from tool docstrings.
vs alternatives: More maintainable than manually-documented schemas because they are auto-generated from code, reducing the risk of documentation drift and enabling IDE autocomplete without additional configuration.
Exposes Alpaca TradingClient methods as MCP tools for querying and managing account state, including account details (cash, buying power, equity), position tracking (open positions, P&L, Greeks for options), and portfolio metrics. Each tool wraps a specific TradingClient method (e.g., get_account(), get_positions(), get_position(symbol)) and returns structured data formatted for LLM consumption. The server maintains no local state; all queries hit the live Alpaca API, ensuring real-time accuracy.
Unique: Directly wraps Alpaca's TradingClient.get_account() and get_positions() methods without intermediate caching or aggregation layers, ensuring every query reflects the current server-side state. The tool set includes position-level Greeks extraction for options, which requires parsing Alpaca's options position objects and exposing Greek values as first-class fields.
vs alternatives: More current than tools that cache account state because every query hits the live API, and includes native options Greeks support which generic portfolio trackers often omit.
Provides access to Alpaca's StockHistoricalDataClient for querying historical market data, including bars (OHLCV candles), quotes (bid/ask spreads), and latest prices across multiple timeframes (minute, hour, day, week, month). Tools accept symbol(s), date ranges, and timeframe parameters, returning structured arrays of price data suitable for technical analysis, backtesting, and strategy validation. The server supports batch queries for multiple symbols in a single request, reducing round-trips.
Unique: Integrates Alpaca's StockHistoricalDataClient directly, supporting batch queries for multiple symbols and flexible timeframe selection (minute through month) without requiring separate API calls per symbol or timeframe. The tool set exposes both bars (OHLCV) and quotes (bid/ask) as distinct tools, allowing LLMs to choose the appropriate data type for their analysis.
vs alternatives: More efficient than tools that query one symbol at a time because batch queries reduce API round-trips, and includes native support for multiple timeframes which generic data APIs often require manual aggregation to provide.
Exposes Alpaca TradingClient order methods as MCP tools for creating, modifying, and canceling orders across stocks, ETFs, crypto, and options. Tools support multiple order types (market, limit, stop, stop-limit, trailing-stop) and time-in-force options (day, gtc, opg, cls). The server translates natural language order descriptions (e.g., 'buy 100 shares of AAPL at market') into structured order objects with proper parameter validation, then submits to Alpaca's order execution engine. All orders are subject to account buying power and position limits.
Unique: Wraps Alpaca's TradingClient.submit_order(), replace_order(), and cancel_order() methods with natural language parameter extraction, allowing LLMs to describe order intent in conversational terms (e.g., 'place a stop-loss at $150') which the tool translates to structured order parameters. The server maintains no order state; all order management is delegated to Alpaca's order engine.
vs alternatives: More flexible than fixed-template order tools because it supports all Alpaca order types and time-in-force options, and integrates directly with Alpaca's execution engine rather than simulating orders locally.
