What is Fastn UCL?
Fastn UCL provides the essential infrastructure to connect your AI agents to the tools your users rely on every day. It's a production-ready orchestration layer designed to solve the complex challenges of security, multi-tenancy, and scalability, allowing your AI to move from simply suggesting to securely taking action. If you're building an AI product for SaaS or enterprise customers, Fastn UCL is the bridge that makes your agent's capabilities a practical reality.
Key Features
Fastn UCL is more than just a protocol; it's a complete, managed solution that handles the difficult parts of AI tool integration, so you can focus on building your core product.
🛍️ Embeddable, White-Labeled App Store Empower your users with a self-service, in-app marketplace where they can securely connect their own tools. You provide a seamless, branded experience, and Fastn UCL handles the underlying authentication, permissions, and credential management for over 1,500 applications.
⚙️ Single Orchestration Layer Connect once, command everywhere. Integrate your MCP-compatible AI agent with a single Fastn UCL endpoint to gain access to your users' entire tool stack—from Slack and Jira to Salesforce and internal APIs. This unified layer eliminates the need to write and maintain brittle, custom logic for every tool and every customer.
🛡️ Governed AI Action Execution Let your AI take real, meaningful actions with complete confidence. Every command is routed through Fastn UCL, which enforces tenant-specific permissions and logs every action. You gain full control and visibility, ensuring your agent operates strictly within the boundaries each user has authorized.
📈 Built-in Monitoring & Observability Gain real-time visibility into every action your AI agent performs across all tenants. Our centralized dashboard allows you to track tool usage, analyze performance, and rapidly debug connection issues, providing the operational insight needed for a production-grade service.
Unique Advantages
True Multi-Tenancy by Design: Unlike solutions that require you to manage separate workflows for each user, Fastn UCL offers true, built-in multi-tenancy. This dramatically simplifies your architecture and allows you to scale effortlessly.
Dynamic Schema Adaptation: Enterprise tools and APIs are constantly changing. While other solutions rely on rigid connections that break when schemas change, Fastn UCL is designed to adapt, ensuring your integrations remain stable and reliable.

Frequently Asked Questions
1. What is the difference between MCP and Fastn UCL? MCP (Model Context Protocol) is the open standard that defines how an AI agent should communicate with tools. Fastn UCL is a fully managed, production-ready platform that implements that standard and solves the practical challenges MCP alone does not address, such as multi-tenancy, enterprise security, monitoring, and scalability. Think of MCP as the blueprint and UCL as the professionally constructed, feature-complete building.
2. Do I need to host my own server? No. Fastn UCL is a fully hosted and managed solution. You don’t need to worry about managing infrastructure, authentication, or scaling. You simply connect your agent to your secure Fastn endpoint, and we handle the rest.
3. Is Fastn UCL secure enough for enterprise use? Absolutely. Security is at the core of our architecture. Fastn UCL provides tenant-level isolation, built-in authentication, and fine-grained access controls. The platform is SOC 2 Type II certified, ISO certified, and designed to meet stringent enterprise compliance requirements, including GDPR, HIPAA, and PCI.
