By the end, you'll have a working Msg91 agent that can send sms to new customer leads, list all ongoing marketing campaigns, fetch failed event logs from last week through natural language commands. This guide will help you understand how to give your CrewAI agent real control over a Msg91 account through Composio's Msg91 MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Msg91 with - [OpenAI Agents SDK](https://composio.dev/toolkits/msg91/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/msg91/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/msg91/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/msg91/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/msg91/framework/codex) - [OpenClaw](https://composio.dev/toolkits/msg91/framework/openclaw) - [Hermes](https://composio.dev/toolkits/msg91/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/msg91/framework/cli) - [Google ADK](https://composio.dev/toolkits/msg91/framework/google-adk) - [LangChain](https://composio.dev/toolkits/msg91/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/msg91/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/msg91/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/msg91/framework/llama-index) ## TL;DR Here's what you'll learn: - Get a Composio API key and configure your Msg91 connection - Set up CrewAI with an MCP enabled agent - Create a Tool Router session or standalone MCP server for Msg91 - Build a conversational loop where your agent can execute Msg91 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 Msg91 MCP server, and what's possible with it? The Msg91 MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Msg91 account. It provides structured and secure access to your SMS, campaign, and user event data, so your agent can perform actions like sending SMS messages, tracking campaigns, recording user events, and monitoring delivery failures on your behalf. - Send personalized SMS messages: Let your agent dispatch SMS messages to one or multiple recipients, making customer outreach fast and automated. - List and track marketing campaigns: Instantly retrieve an overview of all your ongoing or past campaigns, including support for pagination. - Create and log user events: Easily record user actions and behaviors in Msg91 Segmento so you can automate engagement and track interactions. - Retrieve available event types: Ask your agent to list all defined event types to keep your analytics and segmentation organized and up to date. - Monitor failed events for campaigns: Quickly inspect which events failed validation for any campaign, helping you troubleshoot and optimize your communication workflows. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `MSG91_CREATE_USER_EVENTS` | Create User Events | Create and track user events in MSG91 Segmento for customer behavior analysis and segmentation. Use this tool to record user actions and behaviors such as logins, purchases, page views, button clicks, or any custom events. These events help build user profiles and enable targeted campaigns based on user behavior. Examples: - Track user login events for engagement analysis - Record purchase events with product details for sales tracking - Log page views and clicks for behavior analytics - Capture custom events with properties for detailed segmentation | | `MSG91_GET_EVENT_TYPES` | Get Event Types | Retrieves all event types configured in MSG91 Segmento. Event types represent different user actions and behaviors that can be tracked (e.g., purchases, signups, page views). Use this action to discover what events are available for tracking user behavior in your Segmento account. No parameters required - returns all event types. | | `MSG91_GET_FAILED_EVENTS` | Get Failed Events | Retrieve failed user events from a MSG91 Segmento campaign. This tool fetches events that failed to process during campaign execution, helping you identify and debug issues such as validation errors, invalid recipients, or missing required data. Use this when you need to: - Investigate why certain events didn't process successfully - Get detailed failure reasons for troubleshooting - Monitor campaign health and identify patterns in failures - Retrieve failed events within a specific date range Results are paginated for large datasets. Requires a valid campaign_id from a Segmento campaign. | | `MSG91_LIST_CAMPAIGNS` | List Campaigns | Tool to list all campaigns in Segmento. Use when you need to retrieve campaigns with pagination support. | | `MSG91_RESEND_OTP` | Resend OTP | Resend OTP to the same mobile number via text message or voice call. Use when the original OTP was not received or expired, and the user needs a new code sent to the same number. | | `MSG91_SEND_OTP` | Send OTP | Tool to send OTP (One-Time Password) to a mobile number using a pre-configured MSG91 template. Use when you need to verify user phone numbers for authentication, account registration, password reset, or transaction confirmation. | | `MSG91_SEND_SMS_V5` | Send SMS via Flow (V5) | Send SMS messages using pre-defined templates via MSG91 Flow API v5. Use when you need to send template-based SMS with dynamic variable substitution to single or multiple recipients. Templates must be created and approved in MSG91 dashboard before use. | | `MSG91_VERIFY_OTP` | Verify OTP | Tool to verify an OTP (One-Time Password) sent to a mobile number. Use when you need to confirm that the OTP code entered by the user matches the one sent via Send OTP API. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Msg91 MCP server is an implementation of the Model Context Protocol that connects your AI agent to Msg91. It provides structured and secure access so your agent can perform Msg91 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 Msg91 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 Msg91 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 Msg91 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 Msg91 **What's happening:** - You create a Msg91 only session through Composio - Composio returns an MCP HTTP URL that exposes Msg91 tools ```python composio_client = Composio(api_key=COMPOSIO_API_KEY) session = composio_client.create(user_id=COMPOSIO_USER_ID, toolkits=["msg91"]) 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=["msg91"], ) 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 Msg91 through Composio's Tool Router. The agent can perform Msg91 operations through natural language commands.

With a standalone Msg91 MCP server, the agents and LLMs can only access a fixed set of Msg91 tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Msg91 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 Msg91 tools. ### Can I manage the permissions and scopes for Msg91 while using Tool Router? Yes, absolutely. You can configure which Msg91 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 Msg91 data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
