Why Enterprises Need More Than Basic MCP

Model Context Protocol standardizes how AI models talk to tools—a critical first step. But enterprise environments face more complex challenges.

No Build-in Authentication

Enterprise security adapts based on user, role, and scenario. Permissions vary by context and purpose.

MCP LIMITATION

No built-in auth or access control

UCL SOLUTION

Enterprise-grade identity & access management

Multiple Tenant Contexts

Enterprise AI serves different departments, customers, and regions—each with unique data and requirements.

MCP LIMITATION

No concept of tenancy or isolation

UCL SOLUTION

Complete multi-tenant architecture

Dynamic Data That Changes Constantly

Enterprise data sources update frequently. APIs evolve, database structures change, and configurations shift.

MCP LIMITATION

Rigid connections break when schemas change

UCL SOLUTION

Adaptive handling accommodates changes

Enterprise Scalability

Enterprise deployments need to support thousands of users and hundreds of tools without performance degradation.

MCP LIMITATION

Breaks as tool count grows

UCL SOLUTION

Enterprise-grade scalability

Enterprise Security & Data Privacy

Enterprise organizations require robust security controls for sensitive data. The basic MCP implementation creates potential security and privacy challenges in enterprise settings.

MCP LIMITATION

Limited enterprise security controls

UCL SOLUTION

Enhanced security with access controls and monitoring

Compliance Requirements

Enterprise AI faces regulatory scrutiny. Auditors need complete records of who did what, when, and why.

Real-World Analogy

You say: "Send this to the team."

Email us here

Fastn knows:

This tenant uses Teams → it sends it to Teams
Another tenant uses Slack → message goes to Slack

You don't write if-statements. You just issue commands.

You say: "Fetch yesterday’s orders."

Email us here

Fastn knows:

Customer A runs on Shopify
Customer B uses Magento
Customer C has a custom-built order system

No branching logic. Just plug in Fastn.

Built-in Multitenancy

Different customers. Different apps. One secure platform. With Fastn, each customer {tenant} gets their own secure space. It auto detects their apps and sends the same command to the right one.

Developer-First SDK

Connect to our hosted endpoint and focus on building, not infrastructure.

SDK

Context-Aware Execution

Same command, different systems. Fastn automatically routes your commands to the right service based on tenant configuration.

Tenant 1 uses Slack? Command goes to Slack.

Tenant 2 uses Microsoft Teams? Same command, different destination.

No rewrites, no conditionals, no headaches.

from fastn import FastnClient

client1 = FastnClient(
    api_key="your_api_key", 
    space_id="your_space_id", 
    tenant_id="tenant 1"
)

response = client1.execute_action(
        prompt="Send an alert to the team 🚀"
    )

→ Add a new tenant with different tools? No code changes needed.

client2 = FastnClient(
    api_key="your_api_key", 
    space_id="your_space_id", 
    tenant_id="tenant 2"
)

response = client2.execute_action(
        prompt="Send an alert to the team 🚀"
    )

client2 = FastnClient(
    api_key="your_api_key",
