This guide walks you through connecting PDFgen to CrewAI using the Composio tool router. By the end, you'll have a working PDFgen agent that can create templates, update your templates, generate pdfs, view your account, and review usage logs through natural language commands. This guide will help you understand how to give your CrewAI agent real control over a PDFgen account through Composio's PDFgen MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved.
PDFgen is a document generation service for creating PDFs from templates, HTML, Markdown, or natural-language prompts. It helps teams produce reusable, consistent PDFs while tracking templates and usage logs.

This guide will help you understand how to give your CrewAI agent real control over a PDFgen account through Composio's PDFgen MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.
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:
The PDFgen MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your PDFgen account. It provides structured and secure access to your PDF generation, templates, account details, and usage history, so your agent can create templates, generate PDFs, manage saved templates, review credit usage, and inspect recent activity on your behalf.
Composio's Composio SDK helps agents find the right tools for a task at runtime. You can plug in multiple toolkits (like Gmail, HubSpot, and GitHub), and the agent will identify the relevant app and action to complete multi-step workflows. This can reduce token usage and improve the reliability of tool calls. Read more here: Getting started with Composio SDK
The tool router generates a secure MCP URL that your agents can access to perform actions.
The Composio SDK follows a three-phase workflow:

Karan skipped his own birthday party to fix our critical issue. It was 10pm and he diverted his Waymo to help us instead. This really sets the bar — it shows the commitment you need when users rely on your software.
A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.
We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.
As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.
Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
With hands-on help from their founder, we integrated Gmail and Google Drive in just 30 minutes. This level of personal support and commitment is exactly what startups should strive for.
