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 Async interview MCP server, and what's possible with it? The Async interview MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Async interview account. It provides structured and secure access to your interview management dashboard, so your agent can list jobs, update interview details, and delete completed jobs automatically on your behalf. - Comprehensive job listing and retrieval: Instantly fetch a complete list of all your interview jobs, making it easy to monitor hiring activity or review open positions. - Automated job updates: Direct your agent to update the details of any existing interview job—adjusting job info, interview deadlines, or requirements as your needs evolve. - Effortless job deletion: Have your agent permanently remove interview jobs after you've reviewed candidate responses, keeping your hiring dashboard organized and clutter-free. - Streamlined interview process management: Let your agent help you keep interview workflows up to date by making changes or cleaning up jobs without manual effort. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ASYNC_INTERVIEW_DELETE_JOB` | Delete Job | Tool to delete an interview job.

Use when you need to display or manage existing jobs. | | `ASYNC_INTERVIEW_UPDATE_JOB` | Update Job | Tool to update an existing interview job. Use when you need to modify job details after creation. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Async interview MCP server is an implementation of the Model Context Protocol that connects your AI agent to Async interview. It provides structured and secure access so your agent can perform Async interview 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 Async interview - 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 Async interview - MCPServerStreamableHTTP connects to the Async interview 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 Async interview 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 Async interview composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["async_interview"], ) 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 Async interview endpoint - The agent uses GPT-5 to interpret user commands and perform Async interview operations - The instructions field defines the agent's role and behavior ```python # Attach the MCP server to a Pydantic AI Agent async_interview_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[async_interview_mcp], instructions=( "You are a Async interview assistant. Use Async interview 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 - Async interview 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 Async interview.\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 Async interview composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["async_interview"], ) 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 async_interview_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[async_interview_mcp], instructions=( "You are a Async interview assistant. Use Async interview 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 Async interview.\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 Async interview through Composio's Tool Router. With this setup, your agent can perform real Async interview 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 + Async interview 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 Async interview MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/async_interview/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/async_interview/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/async_interview/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/async_interview/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/async_interview/framework/codex) - [OpenClaw](https://composio.dev/toolkits/async_interview/framework/openclaw) - [Hermes](https://composio.dev/toolkits/async_interview/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/async_interview/framework/cli) - [Google ADK](https://composio.dev/toolkits/async_interview/framework/google-adk) - [LangChain](https://composio.dev/toolkits/async_interview/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/async_interview/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/async_interview/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/async_interview/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/async_interview/framework/crew-ai) ## Related Toolkits - [Ashby](https://composio.dev/toolkits/ashby) - Ashby is an applicant tracking system that handles job postings, candidate management, and hiring analytics. - [Bamboohr](https://composio.dev/toolkits/bamboohr) - BambooHR is a cloud-based HR management platform for small and mid-sized businesses.

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