Pydantic AI is a Python framework for building AI agents with strong typing and validation. It leverages Pydantic's data validation capabilities to create robust, type-safe AI applications. Key features include: - Type Safety: Built on Pydantic for automatic data validation - MCP Support: Native support for Model Context Protocol servers - Streaming: Built-in support for streaming responses - Async First: Designed for async/await patterns ## What is the Alpha vantage MCP server, and what's possible with it? The Alpha Vantage MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Alpha Vantage account. It provides structured and secure access to real-time and historical financial data, so your agent can fetch market prices, analyze commodities, review company financials, and retrieve earnings transcripts on your behalf. - Get global commodities and market prices: Instantly retrieve real-time and historical price indices for all major commodities and markets—including aluminum, copper, coffee, corn, and crude oil. - Analyze company financial statements: Ask your agent to fetch detailed annual or quarterly balance sheets for any supported company, making fiscal analysis a breeze. - Access upcoming earnings calendars: Pull comprehensive earnings schedules for the next three months, so you never miss an important financial event. - Retrieve earnings call transcripts with sentiment: Automatically obtain full-text earnings call transcripts for a given company and quarter, including sentiment signals to help you gauge market tone. - Perform historical data research: Let your agent gather time series data for commodities and financial indicators, supporting deeper market research and trend analysis. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ALPHA_VANTAGE_ALL_COMMODITIES` | Get All Commodities Price Index | Tool to retrieve the global price index of all commodities. use when you need monthly, quarterly, or annual aggregated price index data for commodities. | | `ALPHA_VANTAGE_ALUMINUM` | ALUMINUM | Tool to fetch global aluminum prices. use when you need monthly, quarterly, or annual lme aluminum price data. | | `ALPHA_VANTAGE_BALANCE_SHEET` | Balance Sheet | Tool to return annual and quarterly balance sheets for a company. use when you need detailed fiscal statements for analysis. | | `ALPHA_VANTAGE_BRENT` | Brent Crude Oil Prices | Tool to fetch brent crude oil prices. use when you need daily, weekly, or monthly brent price data. | | `ALPHA_VANTAGE_COFFEE` | Global Coffee Price | Tool to retrieve the global coffee price series. use when you need historical monthly, quarterly, or annual coffee prices. | | `ALPHA_VANTAGE_COPPER` | COPPER | Tool to fetch global price of copper in monthly, quarterly, and annual intervals. use when you need historical copper price series for analysis. | | `ALPHA_VANTAGE_CORN` | Corn | Tool to retrieve global price of corn in monthly, quarterly, and annual intervals. use after verifying api key when you need historical corn price data. | | `ALPHA_VANTAGE_COTTON` | COTTON | Tool to retrieve global cotton prices in monthly, quarterly, and annual intervals. use when you need historical cotton price data. | | `ALPHA_VANTAGE_EARNINGS_CALENDAR` | Earnings Calendar | Tool to return the earnings calendar for the next three months. use when you need a schedule of upcoming earnings across symbols. | | `ALPHA_VANTAGE_EARNINGS_CALL_TRANSCRIPT` | Earnings Call Transcript | Tool to retrieve the earnings call transcript for a given company and quarter. use after confirming symbol and quarter. returns full transcript text and associated llm-based sentiment signals. | | `ALPHA_VANTAGE_FX_DAILY` | FX Daily Time Series | Tool to fetch daily time series (open, high, low, close) for a currency pair. use after confirming base and quote currency codes to retrieve historical daily fx rates. | | `ALPHA_VANTAGE_FX_MONTHLY` | FX Monthly Time Series | Tool to get monthly time series (open, high, low, close) for a currency pair. use when you need historical monthly forex data for a given currency pair. | | `ALPHA_VANTAGE_INCOME_STATEMENT` | Income Statement | Tool to fetch annual and quarterly income statements. use after confirming the company symbol. | | `ALPHA_VANTAGE_IPO_CALENDAR` | IPO Calendar | Tool to retrieve the ipo calendar for the next three months. use when you need a list of upcoming ipo events across markets. | | `ALPHA_VANTAGE_LISTING_STATUS` | Listing Status | Tool to fetch listing status of us stocks and etfs. use when you need active or delisted securities as of a date. | | `ALPHA_VANTAGE_NEWS_SENTIMENT` | News Sentiment | Tool to fetch live and historical market news & sentiment. use when you need curated news articles with sentiment scores for specified tickers and topics. | | `ALPHA_VANTAGE_SPLITS` | Stock Splits | Tool to retrieve historical stock split events for a symbol. use when you need past split dates and ratio details before analyzing corporate actions. | | `ALPHA_VANTAGE_SUGAR` | Global Sugar Price | Tool to retrieve the global sugar price series. use when you need historical monthly, quarterly, or annual sugar prices. | | `ALPHA_VANTAGE_TECHNICAL_INDICATOR` | Technical Indicator | Tool to fetch technical indicators for the specified equity or currency pair. use after obtaining time series to compute moving averages or oscillators. | | `ALPHA_VANTAGE_WHEAT` | WHEAT | Tool to fetch global price of wheat. use when you need historical wheat prices in monthly, quarterly, or annual intervals. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Alpha vantage MCP server is an implementation of the Model Context Protocol that connects your AI agent to Alpha vantage. It provides structured and secure access so your agent can perform Alpha vantage operations on your behalf through a secure, permission-based interface. With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster. ## Step-by-step Guide ### 1. Prerequisites Before starting, make sure you have: - Python 3.9 or higher - A Composio account with an active API key - Basic familiarity with Python and async programming ### 1. Getting API Keys for OpenAI and Composio OpenAI API Key - Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider. - Keep the API key safe. Composio API Key - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Navigate to your API settings and generate a new API key. - Store this key securely as you'll need it for authentication. ### 2. Install dependencies Install the required libraries. What's happening: - composio connects your agent to external SaaS tools like Alpha vantage - pydantic-ai lets you create structured AI agents with tool support - python-dotenv loads your environment variables securely from a .env file ```bash pip install composio pydantic-ai python-dotenv ``` ### 3. Set up environment variables Create a .env file in your project root. What's happening: - COMPOSIO_API_KEY authenticates your agent to Composio's API - USER_ID associates your session with your account for secure tool access - OPENAI_API_KEY to access OpenAI LLMs ```bash COMPOSIO_API_KEY=your_composio_api_key_here USER_ID=your_user_id_here OPENAI_API_KEY=your_openai_api_key ``` ### 4. Import dependencies What's happening: - We load environment variables and import required modules - Composio manages connections to Alpha vantage - MCPServerStreamableHTTP connects to the Alpha vantage MCP server endpoint - Agent from Pydantic AI lets you define and run the AI assistant ```python import asyncio import os from dotenv import load_dotenv from composio import Composio from pydantic_ai import Agent from pydantic_ai.mcp import MCPServerStreamableHTTP load_dotenv() ``` ### 5. Create a Tool Router Session What's happening: - We're creating a Tool Router session that gives your agent access to Alpha vantage tools - The create method takes the user ID and specifies which toolkits should be available - The returned session.mcp.url is the MCP server URL that your agent will use ```python async def main(): api_key = os.getenv("COMPOSIO_API_KEY") user_id = os.getenv("USER_ID") if not api_key or not user_id: raise RuntimeError("Set COMPOSIO_API_KEY and USER_ID in your environment") # Create a Composio Tool Router session for Alpha vantage composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["alpha_vantage"], ) url = session.mcp.url if not url: raise ValueError("Composio session did not return an MCP URL") ``` ### 6. Initialize the Pydantic AI Agent What's happening: - The MCP client connects to the Alpha vantage endpoint - The agent uses GPT-5 to interpret user commands and perform Alpha vantage operations - The instructions field defines the agent's role and behavior ```python # Attach the MCP server to a Pydantic AI Agent alpha_vantage_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[alpha_vantage_mcp], instructions=( "You are a Alpha vantage assistant. Use Alpha vantage tools to help users " "with their requests. Ask clarifying questions when needed." ), ) ``` ### 7. Build the chat interface What's happening: - The agent reads input from the terminal and streams its response - Alpha vantage API calls happen automatically under the hood - The model keeps conversation history to maintain context across turns ```python # Simple REPL with message history history = [] print("Chat started! Type 'exit' or 'quit' to end.\n") print("Try asking the agent to help you with Alpha vantage.\n") while True: user_input = input("You: ").strip() if user_input.lower() in {"exit", "quit", "bye"}: print("\nGoodbye!") break if not user_input: continue print("\nAgent is thinking...\n", flush=True) async with agent.run_stream(user_input, message_history=history) as stream_result: collected_text = "" async for chunk in stream_result.stream_output(): text_piece = None if isinstance(chunk, str): text_piece = chunk elif hasattr(chunk, "delta") and isinstance(chunk.delta, str): text_piece = chunk.delta elif hasattr(chunk, "text"): text_piece = chunk.text if text_piece: collected_text += text_piece result = stream_result print(f"Agent: {collected_text}\n") history = result.all_messages() ``` ### 8. Run the application What's happening: - The asyncio loop launches the agent and keeps it running until you exit ```python if __name__ == "__main__": asyncio.run(main()) ``` ## Complete Code ```python import asyncio import os from dotenv import load_dotenv from composio import Composio from pydantic_ai import Agent from pydantic_ai.mcp import MCPServerStreamableHTTP load_dotenv() async def main(): api_key = os.getenv("COMPOSIO_API_KEY") user_id = os.getenv("USER_ID") if not api_key or not user_id: raise RuntimeError("Set COMPOSIO_API_KEY and USER_ID in your environment") # Create a Composio Tool Router session for Alpha vantage composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["alpha_vantage"], ) url = session.mcp.url if not url: raise ValueError("Composio session did not return an MCP URL") # Attach the MCP server to a Pydantic AI Agent alpha_vantage_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[alpha_vantage_mcp], instructions=( "You are a Alpha vantage assistant. Use Alpha vantage tools to help users " "with their requests. Ask clarifying questions when needed." ), ) # Simple REPL with message history history = [] print("Chat started! Type 'exit' or 'quit' to end.\n") print("Try asking the agent to help you with Alpha vantage.\n") while True: user_input = input("You: ").strip() if user_input.lower() in {"exit", "quit", "bye"}: print("\nGoodbye!") break if not user_input: continue print("\nAgent is thinking...\n", flush=True) async with agent.run_stream(user_input, message_history=history) as stream_result: collected_text = "" async for chunk in stream_result.stream_output(): text_piece = None if isinstance(chunk, str): text_piece = chunk elif hasattr(chunk, "delta") and isinstance(chunk.delta, str): text_piece = chunk.delta elif hasattr(chunk, "text"): text_piece = chunk.text if text_piece: collected_text += text_piece result = stream_result print(f"Agent: {collected_text}\n") history = result.all_messages() if __name__ == "__main__": asyncio.run(main()) ``` ## Conclusion You've built a Pydantic AI agent that can interact with Alpha vantage through Composio's Tool Router. With this setup, your agent can perform real Alpha vantage actions through natural language. You can extend this further by: - Adding other toolkits like Gmail, HubSpot, or Salesforce - Building a web-based chat interface around this agent - Using multiple MCP endpoints to enable cross-app workflows (for example, Gmail + Alpha vantage for workflow automation) This architecture makes your AI agent "agent-native", able to securely use APIs in a unified, composable way without custom integrations. ## How to build Alpha vantage MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/alpha_vantage/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/alpha_vantage/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/alpha_vantage/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/alpha_vantage/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/alpha_vantage/framework/codex) - [OpenClaw](https://composio.dev/toolkits/alpha_vantage/framework/openclaw) - [Hermes](https://composio.dev/toolkits/alpha_vantage/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/alpha_vantage/framework/cli) - [Google ADK](https://composio.dev/toolkits/alpha_vantage/framework/google-adk) - [LangChain](https://composio.dev/toolkits/alpha_vantage/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/alpha_vantage/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/alpha_vantage/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/alpha_vantage/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/alpha_vantage/framework/crew-ai) ## Related Toolkits - [Stripe](https://composio.dev/toolkits/stripe) - Stripe is a global online payments platform offering APIs for managing payments, customers, and subscriptions.

With a standalone Alpha vantage MCP server, the agents and LLMs can only access a fixed set of Alpha vantage tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Alpha vantage and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Pydantic AI? Yes, you can. Pydantic AI fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Alpha vantage tools. ### Can I manage the permissions and scopes for Alpha vantage while using Tool Router? Yes, absolutely. You can configure which Alpha vantage scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Alpha vantage data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
