By the end, you'll have a working Epic games agent that can list your recently purchased epic games titles, show current fortnite store offers, check your unreal engine license details through natural language commands. This guide will help you understand how to give your Mastra AI agent real control over a Epic games account through Composio's Epic games MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Epic games with - [OpenAI Agents SDK](https://composio.dev/toolkits/epic_games/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/epic_games/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/epic_games/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/epic_games/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/epic_games/framework/codex) - [OpenClaw](https://composio.dev/toolkits/epic_games/framework/openclaw) - [Hermes](https://composio.dev/toolkits/epic_games/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/epic_games/framework/cli) - [Google ADK](https://composio.dev/toolkits/epic_games/framework/google-adk) - [LangChain](https://composio.dev/toolkits/epic_games/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/epic_games/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/epic_games/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/epic_games/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 Epic games tools - Connect Mastra's MCP client to the Composio generated MCP URL - Fetch Epic games 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 Epic games 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 Epic games MCP server, and what's possible with it? The Epic games MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Epic games account. It provides structured and secure access to your Epic Games platform, so your agent can perform actions like accessing your game library, tracking new releases, viewing purchase history, and managing your account details on your behalf. - Game library insights: Let your agent retrieve and summarize information about your owned and recently played games. - Store browsing and recommendations: Have the agent help you discover new games, sales, and curated recommendations from the Epic Games Store. - Purchase history overview: Get quick reports on your past purchases, including receipts and downloadable content. - Account management assistance: Allow your agent to help update profile details, privacy settings, or linked accounts for a streamlined experience. - Stay up-to-date on releases: Ask the agent to notify you about upcoming game launches, updates, or major events within the Epic Games ecosystem. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `EPIC_GAMES_DELETE_PRESET_METADATA_KEY` | Delete Preset Metadata Key | Tool to delete a metadata key-value pair associated with a Remote Control Preset.

It provides structured and secure access so your agent can perform Epic games 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 Epic games 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 Epic games What's happening: - create spins up a short-lived MCP HTTP endpoint for this user - The toolkits array contains "epic_games" for Epic games 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: ["epic_games"], }, ); const composioMCPUrl = session.mcp.url; console.log("Epic games 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 Epic games 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: "epic_games-mastra-agent", instructions: "You are an AI agent with Epic games 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 Epic games 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: { epic_games: 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: ["epic_games"], }); const composioMCPUrl = session.mcp.url; const mcpClient = new MCPClient({ id: composioUserID as string, servers: { epic_games: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); const composioTools = await mcpClient.getTools(); const agent = new Agent({ name: "epic_games-mastra-agent", instructions: "You are an AI agent with Epic games 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: { epic_games: 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 Epic games 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 Epic games MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/epic_games/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/epic_games/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/epic_games/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/epic_games/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/epic_games/framework/codex) - [OpenClaw](https://composio.dev/toolkits/epic_games/framework/openclaw) - [Hermes](https://composio.dev/toolkits/epic_games/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/epic_games/framework/cli) - [Google ADK](https://composio.dev/toolkits/epic_games/framework/google-adk) - [LangChain](https://composio.dev/toolkits/epic_games/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/epic_games/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/epic_games/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/epic_games/framework/crew-ai) ## Related Toolkits - [Youtube](https://composio.dev/toolkits/youtube) - YouTube is a leading video-sharing platform for uploading, streaming, and discovering content.

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