By the end, you'll have a working Echtpost agent that can show me all postcard templates available, list templates for confidential document delivery, get preview links for secure message templates through natural language commands. This guide will help you understand how to give your CrewAI agent real control over a Echtpost account through Composio's Echtpost MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Echtpost with - [OpenAI Agents SDK](https://composio.dev/toolkits/echtpost/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/echtpost/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/echtpost/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/echtpost/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/echtpost/framework/codex) - [OpenClaw](https://composio.dev/toolkits/echtpost/framework/openclaw) - [Hermes](https://composio.dev/toolkits/echtpost/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/echtpost/framework/cli) - [Google ADK](https://composio.dev/toolkits/echtpost/framework/google-adk) - [LangChain](https://composio.dev/toolkits/echtpost/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/echtpost/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/echtpost/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/echtpost/framework/llama-index) ## TL;DR Here's what you'll learn: - Get a Composio API key and configure your Echtpost connection - Set up CrewAI with an MCP enabled agent - Create a Tool Router session or standalone MCP server for Echtpost - Build a conversational loop where your agent can execute Echtpost operations ## What is CrewAI? CrewAI is a powerful framework for building multi-agent AI systems. It provides primitives for defining agents with specific roles, creating tasks, and orchestrating workflows through crews. Key features include: - Agent Roles: Define specialized agents with specific goals and backstories - Task Management: Create tasks with clear descriptions and expected outputs - Crew Orchestration: Combine agents and tasks into collaborative workflows - MCP Integration: Connect to external tools through Model Context Protocol ## What is the Echtpost MCP server, and what's possible with it? The Echtpost MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Echtpost account. It provides structured and secure access to your Echtpost templates, so your agent can perform actions like listing available postcard templates, retrieving template details, and preparing for secure document creation on your behalf. - Comprehensive template retrieval: Instantly fetch all available postcard and document templates in your Echtpost account for quick reference and selection. - Detailed template information: Allow your agent to access template names, descriptions, preview links, types, and creation timestamps to help you make informed decisions before sending confidential documents. - Template ID lookup for card creation: Let your agent efficiently obtain the necessary template IDs required for creating and dispatching secure postcards or messages. - Preview and validation of design assets: Preview templates visually and validate their suitability—ensuring every document meets your standards before sending. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ECHTPOST_LIST_TEMPLATES` | List templates | This tool retrieves a list of all available templates in the Echtpost account. Templates serve as the base design for postcards and are essential for creating cards. The action operates independently using only an authentication token and returns detailed template information including id, name, description, preview URL, type, and creation time. This action is crucial for viewing templates before creating cards and obtaining the necessary template IDs for subsequent actions. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Echtpost MCP server is an implementation of the Model Context Protocol that connects your AI agent to Echtpost. It provides structured and secure access so your agent can perform Echtpost 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 and API key - A Echtpost connection authorized in Composio - An OpenAI API key for the CrewAI LLM - Basic familiarity with Python ### 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 **What's happening:** - composio connects your agent to Echtpost via MCP - crewai provides Agent, Task, Crew, and LLM primitives - crewai-tools[mcp] includes MCP helpers - python-dotenv loads environment variables from .env ```bash pip install composio crewai crewai-tools[mcp] python-dotenv ``` ### 3. Set up environment variables Create a .env file in your project root. What's happening: - COMPOSIO_API_KEY authenticates with Composio - USER_ID scopes the session to your account - OPENAI_API_KEY lets CrewAI use your chosen OpenAI model ```bash COMPOSIO_API_KEY=your_composio_api_key_here USER_ID=your_user_id_here OPENAI_API_KEY=your_openai_api_key_here ``` ### 4. Import dependencies **What's happening:** - CrewAI classes define agents and tasks, and run the workflow - MCPServerHTTP connects the agent to an MCP endpoint - Composio will give you a short lived Echtpost MCP URL ```python import os from composio import Composio from crewai import Agent, Task, Crew from crewai_tools import MCPServerAdapter import dotenv dotenv.load_dotenv() COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set") ``` ### 5. Create a Composio Tool Router session for Echtpost **What's happening:** - You create a Echtpost only session through Composio - Composio returns an MCP HTTP URL that exposes Echtpost tools ```python composio_client = Composio(api_key=COMPOSIO_API_KEY) session = composio_client.create(user_id=COMPOSIO_USER_ID, toolkits=["echtpost"]) url = session.mcp.url ``` ### 6. Initialize the MCP Server **What's Happening:** - Server Configuration: The code sets up connection parameters including the MCP server URL, streamable HTTP transport, and Composio API key authentication. - MCP Adapter Bridge: MCPServerAdapter acts as a context manager that converts Composio MCP tools into a CrewAI-compatible format. - Agent Setup: Creates a CrewAI Agent with a defined role (Search Assistant), goal (help with internet searches), and access to the MCP tools. - Configuration Options: The agent includes settings like verbose=False for clean output and max_iter=10 to prevent infinite loops. - Dynamic Tool Usage: Once created, the agent automatically accesses all Composio Search tools and decides when to use them based on user queries. ```python server_params = { "url": url, "transport": "streamable-http", "headers": {"x-api-key": COMPOSIO_API_KEY}, } with MCPServerAdapter(server_params) as tools: agent = Agent( role="Search Assistant", goal="Help users search the internet effectively", backstory="You are a helpful assistant with access to search tools.", tools=tools, verbose=False, max_iter=10, ) ``` ### 7. Create a CLI Chatloop and define the Crew **What's Happening:** - Interactive CLI Setup: The code creates an infinite loop that continuously prompts for user input and maintains the entire conversation history in a string variable. - Input Validation: Empty inputs are ignored to prevent processing blank messages and keep the conversation clean. - Context Building: Each user message is appended to the conversation context, which preserves the full dialogue history for better agent responses. - Dynamic Task Creation: For every user input, a new Task is created that includes both the full conversation history and the current request as context. - Crew Execution: A Crew is instantiated with the agent and task, then kicked off to process the request and generate a response. - Response Management: The agent's response is converted to a string, added to the conversation context, and displayed to the user, maintaining conversational continuity. ```python print("Chat started! Type 'exit' or 'quit' to end.\n") conversation_context = "" while True: user_input = input("You: ").strip() if user_input.lower() in ["exit", "quit", "bye"]: print("\nGoodbye!") break if not user_input: continue conversation_context += f"\nUser: {user_input}\n" print("\nAgent is thinking...\n") task = Task( description=( f"Conversation history:\n{conversation_context}\n\n" f"Current request: {user_input}" ), expected_output="A helpful response addressing the user's request", agent=agent, ) crew = Crew(agents=[agent], tasks=[task], verbose=False) result = crew.kickoff() response = str(result) conversation_context += f"Agent: {response}\n" print(f"Agent: {response}\n") ``` ## Complete Code ```python from crewai import Agent, Task, Crew, LLM from crewai_tools import MCPServerAdapter from composio import Composio from dotenv import load_dotenv import os load_dotenv() GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY") COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not GOOGLE_API_KEY: raise ValueError("GOOGLE_API_KEY is not set in the environment.") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set in the environment.") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set in the environment.") # Initialize Composio and create a session composio = Composio(api_key=COMPOSIO_API_KEY) session = composio.create( user_id=COMPOSIO_USER_ID, toolkits=["echtpost"], ) url = session.mcp.url # Configure LLM llm = LLM( model="gpt-5", api_key=os.getenv("OPENAI_API_KEY"), ) server_params = { "url": url, "transport": "streamable-http", "headers": {"x-api-key": COMPOSIO_API_KEY}, } with MCPServerAdapter(server_params) as tools: agent = Agent( role="Search Assistant", goal="Help users with internet searches", backstory="You are an expert assistant with access to Composio Search tools.", tools=tools, llm=llm, verbose=False, max_iter=10, ) print("Chat started! Type 'exit' or 'quit' to end.\n") conversation_context = "" while True: user_input = input("You: ").strip() if user_input.lower() in ["exit", "quit", "bye"]: print("\nGoodbye!") break if not user_input: continue conversation_context += f"\nUser: {user_input}\n" print("\nAgent is thinking...\n") task = Task( description=( f"Conversation history:\n{conversation_context}\n\n" f"Current request: {user_input}" ), expected_output="A helpful response addressing the user's request", agent=agent, ) crew = Crew(agents=[agent], tasks=[task], verbose=False) result = crew.kickoff() response = str(result) conversation_context += f"Agent: {response}\n" print(f"Agent: {response}\n") ``` ## Conclusion You now have a CrewAI agent connected to Echtpost through Composio's Tool Router. The agent can perform Echtpost operations through natural language commands.

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