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 Jobnimbus MCP server, and what's possible with it? The Jobnimbus MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Jobnimbus account. It provides structured and secure access to your CRM and project management data, so your agent can perform actions like managing contacts, scheduling tasks, creating locations, and retrieving account information on your behalf. - Contact management and lookup: Instantly create new contacts or fetch full details and lists of existing contacts for streamlined project tracking and reporting. - Task scheduling and tracking: Direct your agent to create and assign tasks, helping teams stay organized and on top of project to-dos. - Location and job site creation: Quickly add new locations to your Jobnimbus account, ensuring every job and address is properly logged for future reference. - Material order and workflow automation: Let your agent place material orders for jobs and update workflow statuses to keep projects moving smoothly from lead to completion. - Account and attachment management: Retrieve account settings or pull file attachments by ID, supporting seamless document handling and system configuration. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `JOBNIMBUS_ACCOUNT_CREATE_LOCATION` | Create Location | Tool to create a new location in JobNimbus. Use after gathering address and contact details. | | `JOBNIMBUS_ACCOUNT_GET_SETTINGS` | Get Account Settings | Tool to retrieve account-wide settings (workflows, types, sources). Use after authenticating to load or refresh workflow and source mappings. | | `JOBNIMBUS_ACTIVITY_GET` | Get Activity by ID | Retrieves a specific JobNimbus activity by its unique jnid. Activities in JobNimbus represent logged events such as task modifications, contact updates, job creation, and other system actions. Each activity contains details about what changed, who made the change, and when it occurred. Use this action when you need detailed information about a specific activity, such as viewing the full history of changes or understanding who performed an action. | | `JOBNIMBUS_CONTACT_GET` | Get Contact by ID | Tool to retrieve a contact by ID. Use after obtaining the contact’s jnid to fetch full details. | | `JOBNIMBUS_CONTACT_LIST` | List Contacts | Tool to list all contacts. Use when you need to fetch multiple contacts, e.g., for reporting or synchronization. | | `JOBNIMBUS_CONTACT_UPDATE` | Update Contact | Tool to update an existing contact. Use when you have a contact's JNID and need to modify its fields. Call after fetching or creating a contact. | | `JOBNIMBUS_CREATE_FILE_TYPE` | Create File Attachment Type | Creates a new file attachment type in JobNimbus. File types are custom categories used to organize and classify document attachments (e.g., contracts, warranties, photos, permits). You must create a file type before you can upload files with that category. | | `JOBNIMBUS_CREATE_MATERIAL_ORDER` | Create Material Order | Creates a new material order in JobNimbus. A material order tracks materials needed for a job and can be submitted to suppliers.

It provides structured and secure access so your agent can perform Jobnimbus 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 Jobnimbus - 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 Jobnimbus - MCPServerStreamableHTTP connects to the Jobnimbus 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 Jobnimbus 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 Jobnimbus composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["jobnimbus"], ) 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 Jobnimbus endpoint - The agent uses GPT-5 to interpret user commands and perform Jobnimbus operations - The instructions field defines the agent's role and behavior ```python # Attach the MCP server to a Pydantic AI Agent jobnimbus_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[jobnimbus_mcp], instructions=( "You are a Jobnimbus assistant. Use Jobnimbus 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 - Jobnimbus 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 Jobnimbus.\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 Jobnimbus composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["jobnimbus"], ) 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 jobnimbus_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[jobnimbus_mcp], instructions=( "You are a Jobnimbus assistant. Use Jobnimbus 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 Jobnimbus.\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 Jobnimbus through Composio's Tool Router. With this setup, your agent can perform real Jobnimbus 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 + Jobnimbus 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 Jobnimbus MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/jobnimbus/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/jobnimbus/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/jobnimbus/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/jobnimbus/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/jobnimbus/framework/codex) - [OpenClaw](https://composio.dev/toolkits/jobnimbus/framework/openclaw) - [Hermes](https://composio.dev/toolkits/jobnimbus/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/jobnimbus/framework/cli) - [Google ADK](https://composio.dev/toolkits/jobnimbus/framework/google-adk) - [LangChain](https://composio.dev/toolkits/jobnimbus/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/jobnimbus/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/jobnimbus/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/jobnimbus/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/jobnimbus/framework/crew-ai) ## Related Toolkits - [Hubspot](https://composio.dev/toolkits/hubspot) - HubSpot is an all-in-one marketing, sales, and customer service platform.

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