Traditional APIs generally assume a known client making predictable requests. MCP introduces a different pattern: autonomous AI agents can discover and call tools at runtime based on a natural-language objective.
That creates an important engineering question:
How do you secure an API when the caller itself may be autonomous?
In the latest SEOSiri technical deep dive, I explore:
• Where MCP APIs fit inside the API economy
• Why every public API is also an attack surface
• SQL injection, DDoS, BOLA/IDOR, credential abuse and other API threats
• How SEOSiri structures an edge security layer around MCP/API infrastructure
• The open-source @seosiri/security-proxy approach
• Scoped API keys and sandbox-first integration
• How developers can move from their first API key to a live MCP integration
The goal isn't simply to expose another API.
It is to build an agent-ready API layer where access, validation and security are part of the architecture.
