By the end, you'll have a working Helloleads agent that can add a new lead to your sales list, show all leads captured this week, list available lead buckets for new entries through natural language commands. This guide will help you understand how to give your Mastra AI agent real control over a Helloleads account through Composio's Helloleads MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Helloleads with - [ChatGPT](https://composio.dev/toolkits/helloleads/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/helloleads/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/helloleads/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/helloleads/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/helloleads/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/helloleads/framework/codex) - [OpenClaw](https://composio.dev/toolkits/helloleads/framework/openclaw) - [Hermes](https://composio.dev/toolkits/helloleads/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/helloleads/framework/cli) - [Google ADK](https://composio.dev/toolkits/helloleads/framework/google-adk) - [LangChain](https://composio.dev/toolkits/helloleads/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/helloleads/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/helloleads/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/helloleads/framework/crew-ai) ## TL;DR Here's what you'll learn: - Set up your environment so Mastra, OpenAI, and Composio work together - Create a Tool Router session in Composio that exposes Helloleads tools - Connect Mastra's MCP client to the Composio generated MCP URL - Fetch Helloleads tool definitions and attach them as a toolset - Build a Mastra agent that can reason, call tools, and return structured results - Run an interactive CLI where you can chat with your Helloleads agent ## What is Mastra AI? Mastra AI is a TypeScript framework for building AI agents with tool support. It provides a clean API for creating agents that can use external services through MCP. Key features include: - MCP Client: Built-in support for Model Context Protocol servers - Toolsets: Organize tools into logical groups - Step Callbacks: Monitor and debug agent execution - OpenAI Integration: Works with OpenAI models via @ai-sdk/openai ## What is the Helloleads MCP server, and what's possible with it? The Helloleads MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Helloleads account. It provides structured and secure access to your lead management system, so your agent can perform actions like listing leads, creating new lead records, and managing lead groups on your behalf. - Automated lead creation: Instantly add new leads to Helloleads by providing essential details, keeping your sales pipeline updated without manual data entry. - Comprehensive lead listing: Ask your agent to retrieve and display all leads from your account, making it easy to review, filter, or analyze your prospects. - Lead list management: Have your agent fetch all available lead list keys, so you can organize and segment leads for targeted follow-ups or campaigns. - Streamlined lead assignment: Enable your agent to help assign new leads to specific lists, ensuring every lead is captured in the right place from the start. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `HELLOLEADS_CREATE_LEAD` | Create Lead | Tool to add a new lead into HelloLeads. Use when you need to push a fresh lead record with mandatory first name and list key. | | `HELLOLEADS_LIST_LEADS` | List Leads | Tool to list all leads from HelloLeads. Use after authentication to fetch the entire lead list. Returns empty list if none found. | | `HELLOLEADS_LIST_LISTS` | List Lead Lists | Tool to retrieve all lead list keys from HelloLeads. Use when you need to enumerate available lists for lead insertion. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Helloleads MCP server is an implementation of the Model Context Protocol that connects your AI agent to Helloleads. It provides structured and secure access so your agent can perform Helloleads 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: - Node.js 18 or higher - A Composio account with an active API key - An OpenAI API key - Basic familiarity with TypeScript ### 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 need credits or a connected billing setup to use the models. - Store the key somewhere safe. Composio API Key - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Go to Settings and copy your API key. - This key lets your Mastra agent talk to Composio and reach Helloleads through MCP. ### 2. Install dependencies Install the required packages. What's happening: - @composio/core is the Composio SDK for creating MCP sessions - @mastra/core provides the Agent class - @mastra/mcp is Mastra's MCP client - @ai-sdk/openai is the model wrapper for OpenAI - dotenv loads environment variables from .env ```bash npm install @composio/core @mastra/core @mastra/mcp @ai-sdk/openai dotenv ``` ### 3. Set up environment variables Create a .env file in your project root. What's happening: - COMPOSIO_API_KEY authenticates your requests to Composio - COMPOSIO_USER_ID tells Composio which user this session belongs to - OPENAI_API_KEY lets the Mastra agent call OpenAI models ```bash COMPOSIO_API_KEY=your_composio_api_key_here COMPOSIO_USER_ID=your_user_id_here OPENAI_API_KEY=your_openai_api_key_here ``` ### 4. Import libraries and validate environment What's happening: - dotenv/config auto loads your .env so process.env.* is available - openai gives you a Mastra compatible model wrapper - Agent is the Mastra agent that will call tools and produce answers - MCPClient connects Mastra to your Composio MCP server - Composio is used to create a Tool Router session ```typescript import "dotenv/config"; import { openai } from "@ai-sdk/openai"; import { Agent } from "@mastra/core/agent"; import { MCPClient } from "@mastra/mcp"; import { Composio } from "@composio/core"; import * as readline from "readline"; import type { AiMessageType } from "@mastra/core/agent"; const openaiAPIKey = process.env.OPENAI_API_KEY; const composioAPIKey = process.env.COMPOSIO_API_KEY; const composioUserID = process.env.COMPOSIO_USER_ID; if (!openaiAPIKey) throw new Error("OPENAI_API_KEY is not set"); if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set"); if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set"); const composio = new Composio({ apiKey: composioAPIKey as string, }); ``` ### 5. Create a Tool Router session for Helloleads What's happening: - create spins up a short-lived MCP HTTP endpoint for this user - The toolkits array contains "helloleads" for Helloleads access - session.mcp.url is the MCP URL that Mastra's MCPClient will connect to ```typescript async function main() { const session = await composio.create( composioUserID as string, { toolkits: ["helloleads"], }, ); const composioMCPUrl = session.mcp.url; console.log("Helloleads MCP URL:", composioMCPUrl); ``` ### 6. Configure Mastra MCP client and fetch tools What's happening: - MCPClient takes an id for this client and a list of MCP servers - The headers property includes the x-api-key for authentication - getTools fetches the tool definitions exposed by the Helloleads toolkit ```typescript const mcpClient = new MCPClient({ id: composioUserID as string, servers: { nasdaq: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); console.log("Fetching MCP tools from Composio..."); const composioTools = await mcpClient.getTools(); console.log("Number of tools:", Object.keys(composioTools).length); ``` ### 7. Create the Mastra agent What's happening: - Agent is the core Mastra agent - name is just an identifier for logging and debugging - instructions guide the agent to use tools instead of only answering in natural language - model uses openai("gpt-5") to configure the underlying LLM ```typescript const agent = new Agent({ name: "helloleads-mastra-agent", instructions: "You are an AI agent with Helloleads tools via Composio.", model: "openai/gpt-5", }); ``` ### 8. Set up interactive chat interface What's happening: - messages keeps the full conversation history in Mastra's expected format - agent.generate runs the agent with conversation history and Helloleads toolsets - maxSteps limits how many tool calls the agent can take in a single run - onStepFinish is a hook that prints intermediate steps for debugging ```typescript let messages: AiMessageType[] = []; console.log("Chat started! Type 'exit' or 'quit' to end.\n"); const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: "> ", }); rl.prompt(); rl.on("line", async (userInput: string) => { const trimmedInput = userInput.trim(); if (["exit", "quit", "bye"].includes(trimmedInput.toLowerCase())) { console.log("\nGoodbye!"); rl.close(); process.exit(0); } if (!trimmedInput) { rl.prompt(); return; } messages.push({ id: crypto.randomUUID(), role: "user", content: trimmedInput, }); console.log("\nAgent is thinking...\n"); try { const response = await agent.generate(messages, { toolsets: { helloleads: composioTools, }, maxSteps: 8, }); const { text } = response; if (text && text.trim().length > 0) { console.log(`Agent: ${text}\n`); messages.push({ id: crypto.randomUUID(), role: "assistant", content: text, }); } } catch (error) { console.error("\nError:", error); } rl.prompt(); }); rl.on("close", async () => { console.log("\nSession ended."); await mcpClient.disconnect(); process.exit(0); }); } main().catch((err) => { console.error("Fatal error:", err); process.exit(1); }); ``` ## Complete Code ```typescript import "dotenv/config"; import { openai } from "@ai-sdk/openai"; import { Agent } from "@mastra/core/agent"; import { MCPClient } from "@mastra/mcp"; import { Composio } from "@composio/core"; import * as readline from "readline"; import type { AiMessageType } from "@mastra/core/agent"; const openaiAPIKey = process.env.OPENAI_API_KEY; const composioAPIKey = process.env.COMPOSIO_API_KEY; const composioUserID = process.env.COMPOSIO_USER_ID; if (!openaiAPIKey) throw new Error("OPENAI_API_KEY is not set"); if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set"); if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set"); const composio = new Composio({ apiKey: composioAPIKey as string }); async function main() { const session = await composio.create(composioUserID as string, { toolkits: ["helloleads"], }); const composioMCPUrl = session.mcp.url; const mcpClient = new MCPClient({ id: composioUserID as string, servers: { helloleads: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); const composioTools = await mcpClient.getTools(); const agent = new Agent({ name: "helloleads-mastra-agent", instructions: "You are an AI agent with Helloleads tools via Composio.", model: "openai/gpt-5", }); let messages: AiMessageType[] = []; const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: "> ", }); rl.prompt(); rl.on("line", async (input: string) => { const trimmed = input.trim(); if (["exit", "quit"].includes(trimmed.toLowerCase())) { rl.close(); return; } messages.push({ id: crypto.randomUUID(), role: "user", content: trimmed }); const { text } = await agent.generate(messages, { toolsets: { helloleads: composioTools }, maxSteps: 8, }); if (text) { console.log(`Agent: ${text}\n`); messages.push({ id: crypto.randomUUID(), role: "assistant", content: text }); } rl.prompt(); }); rl.on("close", async () => { await mcpClient.disconnect(); process.exit(0); }); } main(); ``` ## Conclusion You've built a Mastra AI agent that can interact with Helloleads through Composio's Tool Router. You can extend this further by: - Adding other toolkits like Gmail, Slack, or GitHub - Building a web-based chat interface around this agent - Using multiple MCP endpoints to enable cross-app workflows ## How to build Helloleads MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/helloleads/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/helloleads/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/helloleads/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/helloleads/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/helloleads/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/helloleads/framework/codex) - [OpenClaw](https://composio.dev/toolkits/helloleads/framework/openclaw) - [Hermes](https://composio.dev/toolkits/helloleads/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/helloleads/framework/cli) - [Google ADK](https://composio.dev/toolkits/helloleads/framework/google-adk) - [LangChain](https://composio.dev/toolkits/helloleads/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/helloleads/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/helloleads/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/helloleads/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 Helloleads MCP server, the agents and LLMs can only access a fixed set of Helloleads tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Helloleads and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Mastra AI? Yes, you can. Mastra 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 Helloleads tools. ### Can I manage the permissions and scopes for Helloleads while using Tool Router? Yes, absolutely. You can configure which Helloleads 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 Helloleads 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)
