Fastn UCL: Multi-tenant MCP, Secure AI Agent Connectivity
Fastn UCL: Enterprise-grade multi-tenant MCP that securely connects AI agents to any tool—scalable, compliant, and built for AI orchestration.
Introducing Fastn UCL: The Enterprise MCP Backbone for AI Agents
Fastn UCL is the industry’s first production-ready, multi-tenant Model Context Protocol (MCP) platform engineered exclusively for SaaS providers building intelligent AI agents. It serves as a secure Unified Command Layer — abstracting complexity across hundreds of tools, APIs, and internal systems — so AI agents can reliably execute actions *with context*, *with consent*, and *at scale*. Built from the ground up for enterprise compliance, tenant isolation, and zero-trust architecture, Fastn UCL delivers seamless connectivity, real-time observability, and adaptive schema handling — all without operational overhead.
Getting Started with Fastn UCL
Integration takes minutes, not months. First, register your SaaS environment and onboard supported tools — whether Slack, Salesforce, Snowflake, or custom REST/gRPC services — via Fastn’s secure OAuth and API key workflows. Next, embed Fastn UCL into your AI agent stack using our lightweight SDK or React-based UI component. Your agents instantly gain access to a unified, tenant-aware command interface — complete with automatic token rotation, permission-aware routing, and contextual action validation. Monitor every invocation, audit trail, and latency metric from a single, role-based dashboard.

FAQ from Fastn UCL
What is Fastn UCL?
Fastn UCL is an enterprise-grade, multi-tenant Model Context Protocol (MCP) platform that acts as a secure Unified Command Layer — enabling AI agents to interact safely and consistently with any business system. Designed for SaaS builders, it provides built-in tenant isolation, compliance automation, dynamic tool discovery, and real-time action orchestration — all delivered as a managed service.
What does MCP mean for AI developers?
MCP (Model Context Protocol) is an open specification that standardizes how AI models request, validate, and execute actions against external systems. Fastn UCL implements MCP natively — eliminating custom adapters, reducing integration debt, and ensuring interoperability across AI agents, tools, and vendors.
How does Fastn UCL enforce security at the tenant level?
Every request is validated against tenant-specific policies: identity (SAML/OIDC), authorization (RBAC + ABAC), data residency rules, and action-level consent. All credentials are encrypted at rest and in transit, with hardware-backed key management and quarterly third-party penetration testing.
Can I use Fastn UCL without managing infrastructure?
Absolutely. Fastn UCL is a fully managed cloud service — including global edge routing, auto-scaling compute, encrypted logging, and SOC 2 Type II–certified infrastructure. You bring the AI agent; we handle everything else.
Do you offer SDKs for Python, JavaScript, and mobile?
Yes — official SDKs for TypeScript, Python, and Java, plus community-supported bindings for Rust, Go, and Swift. All include auto-generated type safety, retry logic, and telemetry hooks. Documentation and examples are available at docs.ucl.dev.
How does Fastn UCL handle data residency and compliance per tenant?
Tenants can declare regional preferences (e.g., “EU-only processing”) during onboarding. Fastn enforces strict data boundary controls — routing traffic, storing logs, and executing actions only within designated geographies — backed by contractual commitments and certified compliance frameworks (GDPR, HIPAA, ISO 27001, PCI-DSS).
