POSTBOY
Securing your LLM providers and MCP servers.
Beta now open_
The shift
LLM providers and MCP servers are multiplying fast. Every team is wiring in new models, agents, and tool servers each week — and every new connection widens the surface where prompts, credentials, and data can leak.
What Postboy does
Postboy will be securing your LLM providers and MCP servers.
- Visibility into what your team is actually using.
- Guardrails where they matter.
- An audit trail you can trust.
Built for AI infrastructure
Postboy is an AI infrastructure security company. We treat models and MCP servers as first-class production dependencies — the same way the last decade treated APIs and databases — and give security and platform teams the visibility, guardrails, and incident tooling that maturity demands.

We're onboarding a small group of design partners now. If you're running LLMs or MCP servers in production and want to help shape what we ship, we'd love to talk.
