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 Fidel api MCP server, and what's possible with it? The Fidel api MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Fidel api account. It provides structured and secure access to your Fidel API tools, so your agent can perform actions like creating brands, managing programs, retrieving offers, handling webhooks, and more on your behalf. - Brand and program creation: Easily instruct your agent to register new brands or set up loyalty programs for your business, streamlining onboarding and expansion. - Real-time webhook management: Let your agent create or delete webhooks so you can receive instant notifications for important program events without manual setup. - Detailed entity retrieval: Have your agent fetch comprehensive details about brands, programs, offers, or webhooks whenever you need insights or verification. - Offer and webhook deletion: Direct your agent to remove outdated offers or webhooks, keeping your Fidel API environment clean and up-to-date. - End-to-end automation for payment integrations: Allow your agent to manage the full lifecycle of brands, programs, and event hooks, helping you build seamless payment-linked experiences with minimal effort. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `FIDEL_API_CREATE_BRAND` | Create Brand | Tool to create a new brand on fidel. use when you have brand details and need to register it. this tool sends a post request to /v1/brands with the provided brand data. | | `FIDEL_API_CREATE_PROGRAM` | Create Program | Tool to create a new program. use when registering an offline or online store. use after confirming program name and any optional metadata. | | `FIDEL_API_CREATE_PROGRAM_WEBHOOK` | Create Program Webhook | Tool to register a new webhook for program-related events. use when you need to receive real-time notifications for specific program events in your application. | | `FIDEL_API_DELETE_OFFER` | Delete Offer | Tool to delete a specified offer by its id. use after confirming the correct offer id. | | `FIDEL_API_DELETE_PROGRAM_WEBHOOK` | Delete Program Webhook | Tool to delete a specified webhook for a program. use when you need to remove a program webhook after confirming programid and hookid. | | `FIDEL_API_DELETE_WEBHOOK` | Delete Webhook | Tool to delete a specified webhook. use when you need to remove a webhook by its id. | | `FIDEL_API_GET_BRAND` | Get Brand | Tool to retrieve information about a specific brand. use when you have a brand id and need its details. | | `FIDEL_API_GET_OFFER` | Get Offer | Tool to fetch details of a specific offer. use when you have an offer id and need its full details. | | `FIDEL_API_GET_PROGRAM` | Get Program | Tool to retrieve details of a specific program. use when you have a program id and need its full details. | | `FIDEL_API_GET_WEBHOOK` | Get Webhook | Tool to retrieve details of a specific webhook. use when you have a webhook id and need its full details. | | `FIDEL_API_LIST_BRANDS` | List Brands | Tool to list all brands. use when you need to retrieve a paginated list of all available brands. | | `FIDEL_API_LIST_CARDS` | List Cards | Tool to list all cards for a specific program. use when you have a programid and need to retrieve associated card records. | | `FIDEL_API_LIST_LOCATIONS` | List Locations | Tool to list all locations for a program. use when you need to retrieve paginated store locations within a specific program. | | `FIDEL_API_LIST_OFFERS` | List Offers | Tool to list all offers. use when you need to retrieve offers after applying optional filters. | | `FIDEL_API_LIST_PROGRAMS` | List Programs | Tool to list fidel programs. use when you need to retrieve available programs with optional pagination. | | `FIDEL_API_LIST_PROGRAM_WEBHOOKS` | List Program Webhooks | Tool to list all registered webhooks for a specific program. use when you need to retrieve existing webhooks after confirming the programid. | | `FIDEL_API_LIST_TRANSACTIONS` | List Transactions | Tool to list transactions. use when you need to page through and/or filter transactions. | | `FIDEL_API_UPDATE_PROGRAM` | Update Program | Tool to update a program's name, icon, metadata, or status. use after confirming the program id and desired updates. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Fidel api MCP server is an implementation of the Model Context Protocol that connects your AI agent to Fidel api. It provides structured and secure access so your agent can perform Fidel api 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 Fidel api - 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 Fidel api - MCPServerStreamableHTTP connects to the Fidel api 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 Fidel api 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 Fidel api composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["fidel_api"], ) 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 Fidel api endpoint - The agent uses GPT-5 to interpret user commands and perform Fidel api operations - The instructions field defines the agent's role and behavior ```python # Attach the MCP server to a Pydantic AI Agent fidel_api_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[fidel_api_mcp], instructions=( "You are a Fidel api assistant. Use Fidel api 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 - Fidel api 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 Fidel api.\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 Fidel api composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["fidel_api"], ) 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 fidel_api_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[fidel_api_mcp], instructions=( "You are a Fidel api assistant. Use Fidel api 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 Fidel api.\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 Fidel api through Composio's Tool Router. With this setup, your agent can perform real Fidel api 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 + Fidel api 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 Fidel api MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/fidel_api/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/fidel_api/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/fidel_api/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/fidel_api/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/fidel_api/framework/codex) - [OpenClaw](https://composio.dev/toolkits/fidel_api/framework/openclaw) - [Hermes](https://composio.dev/toolkits/fidel_api/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/fidel_api/framework/cli) - [Google ADK](https://composio.dev/toolkits/fidel_api/framework/google-adk) - [LangChain](https://composio.dev/toolkits/fidel_api/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/fidel_api/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/fidel_api/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/fidel_api/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/fidel_api/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 Fidel api MCP server, the agents and LLMs can only access a fixed set of Fidel api tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Fidel api 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 Fidel api tools. ### Can I manage the permissions and scopes for Fidel api while using Tool Router? Yes, absolutely. You can configure which Fidel api 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 Fidel api data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) ยท [Composio docs](https://docs.composio.dev/llms.txt)
