By the end, you'll have a working Pdf api io agent that can list all your saved pdf templates, show templates created this month, find templates for invoices and receipts through natural language commands. This guide will help you understand how to give your Mastra AI agent real control over a Pdf api io account through Composio's Pdf api io MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Pdf api io with - [OpenAI Agents SDK](https://composio.dev/toolkits/pdf_api_io/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/pdf_api_io/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/pdf_api_io/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/pdf_api_io/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/pdf_api_io/framework/codex) - [OpenClaw](https://composio.dev/toolkits/pdf_api_io/framework/openclaw) - [Hermes](https://composio.dev/toolkits/pdf_api_io/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/pdf_api_io/framework/cli) - [Google ADK](https://composio.dev/toolkits/pdf_api_io/framework/google-adk) - [LangChain](https://composio.dev/toolkits/pdf_api_io/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/pdf_api_io/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/pdf_api_io/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/pdf_api_io/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 Pdf api io tools - Connect Mastra's MCP client to the Composio generated MCP URL - Fetch Pdf api io 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 Pdf api io 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 Pdf api io MCP server, and what's possible with it? The Pdf api io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Pdf api io account. It provides structured and secure access to your PDF templates, so your agent can perform actions like listing available templates, retrieving template details, and managing template-based PDF generation on your behalf. - List all PDF templates: Quickly retrieve a full list of your available PDF templates, making it easy for your agent to access and organize templates as needed. - Template discovery and selection: Allow your agent to browse and identify the right template for generating personalized or standardized documents. - Template-driven automation: Enable your agent to automate document workflows by leveraging pre-existing templates for dynamic PDF creation. - Seamless integration with PDF design tools: Use your agent to bridge between template design and document generation, streamlining PDF-related processes for your apps. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `PDF_API_IO_LIST_TEMPLATES` | List Templates | Tool to list all available templates. Use after authentication to retrieve user's templates. Returns template metadata only; populating or rendering a template requires additional tool calls. Verify returned templates include required fields and variants before proceeding. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Pdf api io MCP server is an implementation of the Model Context Protocol that connects your AI agent to Pdf api io. It provides structured and secure access so your agent can perform Pdf api io 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 Pdf api io 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 Pdf api io What's happening: - create spins up a short-lived MCP HTTP endpoint for this user - The toolkits array contains "pdf_api_io" for Pdf api io 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: ["pdf_api_io"], }, ); const composioMCPUrl = session.mcp.url; console.log("Pdf api io 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 Pdf api io 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: "pdf_api_io-mastra-agent", instructions: "You are an AI agent with Pdf api io 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 Pdf api io 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: { pdf_api_io: 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: ["pdf_api_io"], }); const composioMCPUrl = session.mcp.url; const mcpClient = new MCPClient({ id: composioUserID as string, servers: { pdf_api_io: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); const composioTools = await mcpClient.getTools(); const agent = new Agent({ name: "pdf_api_io-mastra-agent", instructions: "You are an AI agent with Pdf api io 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: { pdf_api_io: 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 Pdf api io 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 Pdf api io MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/pdf_api_io/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/pdf_api_io/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/pdf_api_io/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/pdf_api_io/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/pdf_api_io/framework/codex) - [OpenClaw](https://composio.dev/toolkits/pdf_api_io/framework/openclaw) - [Hermes](https://composio.dev/toolkits/pdf_api_io/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/pdf_api_io/framework/cli) - [Google ADK](https://composio.dev/toolkits/pdf_api_io/framework/google-adk) - [LangChain](https://composio.dev/toolkits/pdf_api_io/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/pdf_api_io/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/pdf_api_io/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/pdf_api_io/framework/crew-ai) ## Related Toolkits - [Google Super](https://composio.dev/toolkits/googlesuper) - Google Super is an all-in-one suite combining Gmail, Drive, Calendar, Sheets, Analytics, and more.

With a standalone Pdf api io MCP server, the agents and LLMs can only access a fixed set of Pdf api io tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Pdf api io 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 Pdf api io tools. ### Can I manage the permissions and scopes for Pdf api io while using Tool Router? Yes, absolutely. You can configure which Pdf api io 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 Pdf api io 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)
