Tool-Result Injection: The MCP Attack System Prompts Miss
A concrete walkthrough of indirect prompt injection delivered via MCP tool responses. The attack, the model's reasoning, and the policy that stops it.
System Prompts vs. Transport Firewalls: Why System Prompts Do Not Equal Security
Discover why system prompts fail as a security boundary for AI agents, and how transport-level MCP proxies provide deterministic guardrails.
Bain Says Every Agentic Platform Needs a Policy Layer. We Built One.
Bain & Company's agentic AI architecture framework calls for centralised policy enforcement across MCP tool calls. Intercept is the open-source implementation.
Why Your Agent Shouldn't Know About Its Spending Limits
Policy enforcement belongs in your tools, not your agent. Here's why the integration point matters for security.
