AgentAuth: Seamless Authentication for AI Agents with 250+ Tools

AgentAuth introduction

The popularity of AI Automation is through the roof, thanks to their insane reasoning and decision-making capability. However, one of the most significant challenges for building genuinely useful AI agents is enabling secure and seamless authentication with the external applications.

These LLMs can write code but cannot execute it; they can select restaurants but cannot order from them; they can draft perfect emails but can’t send them; they can recommend the best hotels but can’t book a stay, leaving a gap between intelligence and action. This gap exists because AI models cannot access your applications or interact with your data securely.

AgentAuth bridges this gap by providing a secure, authenticated connection between AI agents and third-party applications. It enables robust authentication flows that allow agents to seamlessly access and act on your behalf.

Challenge of Auth for AI agents

From our experience building multiple AI solutions for production use cases, we’ve learned that developers’ most significant challenge when building AI apps is managing auth flows for various integration services.

We’ve experimented with existing auth solutions like Nango and Paragon, but they aren’t optimized for AI-specific use cases. Unlike traditional software, where developers directly call APIs, AI automation relies on LLMs to call APIs through function-calling methods, which introduces unique challenges.

AI models are not deterministic and rely on additional context, such as function definitions and parameter details, to reliably call and execute APIs. To enable AI agents to act effectively, a specialized layer for LLM function calls must complement the traditional authentication layer. Each API function calls to third-party services must be optimized for bulletproof reliability. This is essential for creating real-world-ready AI agents capable of handling complex tasks.

Creating and managing in-house auth flows for multiple services is already a complex task—and optimizing them specifically for AI agents makes it even more daunting.

There has to be a better way.

AgentAuth: Auth made Simple for AI Agents

gentAuth is designed to address this very challenge. It eliminates the complexities of managing authentication for AI agents by providing a platform tailored specifically to their needs. Its compatibility with function-calling workflows ensures that AI agents can securely and reliably access the APIs they need to act on your behalf.

Built for Developers, by Developers

As developers, we know firsthand how time-consuming and frustrating it can be to build and maintain auth flows for multiple services. We’ve been there—wrestling with integrations and pouring countless engineering hours into authentication challenges instead of focusing on building features that genuinely add user value.

With that in mind, we created AgentAuth to eliminate this pain point. It’s designed to handle the complexities of authentication so you can focus on what matters most: delivering innovative, user-focused solutions.

AgentAuth is more than just an authentication tool—it’s a developer’s ally in creating real-world-ready AI agents that securely and seamlessly interact with third-party services, saving you time, effort, and resources. Let us handle the backend headaches so you can get back to building great experiences for your users.

Real-world Use cases

AgentAuth makes it easy for you to

  • Customer Support AutomationBuild an AI agent that fetches customer information from HubSpot, drafts responses in Gmail, and updates tickets in Zendesk—all while securely handling sensitive customer data.

  • Meeting SchedulerCreate an AI agent that accesses your Google Calendar, finds available slots, and sends meeting invitations via Slack or email, streamlining scheduling with secure integrations.

  • Sales AssistantsDevelop an AI agent that pulls sales data from Salesforce, compiles a report in Google Sheets, and emails it to your team, automating repetitive tasks securely and efficiently.

  • Developer Workflow AutomationBuild an agent that reviews pull requests on GitHub, updates issues in Jira, and sends deployment notifications on Slack, optimizing development pipelines with minimal effort.

You can forget about dealing with the complexities of authentication flows for these services and focus entirely on building what truly matters for your users.
