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 Icypeas MCP server, and what's possible with it? The Icypeas MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Icypeas account. It provides structured and secure access to professional email discovery and verification, so your agent can perform actions like finding emails, verifying addresses, searching company data, and scanning domains on your behalf. - Accurate email discovery and verification: Instantly find and verify professional email addresses using first name, last name, and company domain to supercharge your outreach or lead generation. - Bulk prospecting and search management: Launch bulk email or profile URL searches for thousands of contacts at once, then track progress and fetch results without manual oversight. - Comprehensive company and people lookup: Search for companies or filter people by name, title, company, and more to enrich your CRM or build targeted prospect lists efficiently. - Domain scanning for role-based emails: Scan entire company domains to discover all available role-based email addresses, simplifying large-scale contact discovery. - Subscription and usage insights: Check your Icypeas subscription details and remaining credits, helping you stay on top of your usage and plan outreach campaigns smarter. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ICYPEAS_BULK_EMAIL_SEARCH` | Bulk Email Search | Initiate a bulk email search job to find professional email addresses for multiple people at once. Use this tool when you need to find emails for more than one person. Provide names (first and/or last) along with company domains or names. The API queues the job and returns a file identifier that can be used with 'Fetch Bulk Search Info' and 'Retrieve Search Results' to check progress and get results. Rate limit: 1 request per second. Maximum 5000 rows per bulk request. | | `ICYPEAS_BULK_FIND_PROFILE_URLS` | Find Profile URLs Bulk | Tool to perform bulk search for profile URLs based on firstname, lastname, and company/domain or job title. Use when you need to find LinkedIn or other social profile URLs for multiple prospects at once (up to 50 per request). This endpoint returns immediate results with profile URLs. Each result includes the found URL (or empty string if not found), a search ID, and a status indicator. | | `ICYPEAS_BULK_REVERSE_EMAIL_LOOKUP` | Bulk Reverse Email Lookup | Tool to find LinkedIn profile URLs for multiple professional email addresses in a single request. Use when you need to reverse lookup 2-50 email addresses to find their associated LinkedIn profiles. Each lookup costs 10 credits per found profile.

Returns a verification item ID that can be used with ICYPEAS_RETRIEVE_SEARCH_RESULTS to get the verification result. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Icypeas MCP server is an implementation of the Model Context Protocol that connects your AI agent to Icypeas. It provides structured and secure access so your agent can perform Icypeas 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 Icypeas - 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 Icypeas - MCPServerStreamableHTTP connects to the Icypeas 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 Icypeas 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 Icypeas composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["icypeas"], ) 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 Icypeas endpoint - The agent uses GPT-5 to interpret user commands and perform Icypeas operations - The instructions field defines the agent's role and behavior ```python # Attach the MCP server to a Pydantic AI Agent icypeas_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[icypeas_mcp], instructions=( "You are a Icypeas assistant. Use Icypeas 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 - Icypeas 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 Icypeas.\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 Icypeas composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["icypeas"], ) 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 icypeas_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[icypeas_mcp], instructions=( "You are a Icypeas assistant. Use Icypeas 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 Icypeas.\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 Icypeas through Composio's Tool Router. With this setup, your agent can perform real Icypeas 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 + Icypeas 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 Icypeas MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/icypeas/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/icypeas/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/icypeas/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/icypeas/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/icypeas/framework/codex) - [OpenClaw](https://composio.dev/toolkits/icypeas/framework/openclaw) - [Hermes](https://composio.dev/toolkits/icypeas/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/icypeas/framework/cli) - [Google ADK](https://composio.dev/toolkits/icypeas/framework/google-adk) - [LangChain](https://composio.dev/toolkits/icypeas/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/icypeas/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/icypeas/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/icypeas/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/icypeas/framework/crew-ai) ## Related Toolkits - [Aeroleads](https://composio.dev/toolkits/aeroleads) - Aeroleads is a B2B lead generation platform for finding business emails and phone numbers.

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