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 Astica ai MCP server, and what's possible with it? The Astica ai MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Astica ai account. It provides structured and secure access to advanced cognitive intelligence APIs, so your agent can perform actions like analyzing audio, transcribing speech, extracting text from images, and automating media understanding tasks on your behalf. - Audio transcription automation: Instantly convert audio files or streams to accurate text using the Analyze Audio tool, perfect for meeting notes, podcasts, or voice memos. - OCR text extraction from images: Quickly read and extract raw text from images (like photos, scanned documents, or screenshots) with the ASTICA_READ_TEXT tool. - Seamless media processing: Let your agent process audio and visual inputs end-to-end, enabling smarter workflows that bridge speech and text content. - Hands-off document digitization: Automate the tedious process of turning printed or handwritten materials into searchable, editable text for downstream applications. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ASTICA_AI_ANALYZE_AUDIO` | Analyze Audio | Tool to analyze audio input for transcription. Use when you need to convert an audio URL or Base64 string to text. | | `ASTICA_AI_ASTICA_READ_TEXT` | ASTICA_READ_TEXT | Perform OCR (Optical Character Recognition) on an image to extract text. Supports HTTPS image URLs and Base64-encoded images. Returns detected text blocks with bounding box coordinates. Works with printed text, handwritten notes, and various image qualities. Note: SVG and WebP formats are not supported. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Astica ai MCP server is an implementation of the Model Context Protocol that connects your AI agent to Astica ai. It provides structured and secure access so your agent can perform Astica ai 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 Astica ai - 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 Astica ai - MCPServerStreamableHTTP connects to the Astica ai 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 Astica ai 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 Astica ai composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["astica_ai"], ) 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 Astica ai endpoint - The agent uses GPT-5 to interpret user commands and perform Astica ai operations - The instructions field defines the agent's role and behavior ```python # Attach the MCP server to a Pydantic AI Agent astica_ai_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[astica_ai_mcp], instructions=( "You are a Astica ai assistant. Use Astica ai 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 - Astica ai 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 Astica ai.\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 Astica ai composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["astica_ai"], ) 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 astica_ai_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[astica_ai_mcp], instructions=( "You are a Astica ai assistant. Use Astica ai 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 Astica ai.\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 Astica ai through Composio's Tool Router. With this setup, your agent can perform real Astica ai 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 + Astica ai 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 Astica ai MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/astica_ai/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/astica_ai/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/astica_ai/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/astica_ai/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/astica_ai/framework/codex) - [OpenClaw](https://composio.dev/toolkits/astica_ai/framework/openclaw) - [Hermes](https://composio.dev/toolkits/astica_ai/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/astica_ai/framework/cli) - [Google ADK](https://composio.dev/toolkits/astica_ai/framework/google-adk) - [LangChain](https://composio.dev/toolkits/astica_ai/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/astica_ai/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/astica_ai/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/astica_ai/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/astica_ai/framework/crew-ai) ## Related Toolkits - [Composio](https://composio.dev/toolkits/composio) - Composio is an integration platform that connects AI agents with hundreds of business tools.

With a standalone Astica ai MCP server, the agents and LLMs can only access a fixed set of Astica ai tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Astica ai 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 Astica ai tools. ### Can I manage the permissions and scopes for Astica ai while using Tool Router? Yes, absolutely. You can configure which Astica ai 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 Astica ai data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
