Model Context Protocol

Context

Quantum computers are expected to break traditional cryptographic systems like RSA and ECC. In response,

Key features of lattice cryptography include:

• Strong Security Guarantees*: It is based on hard mathematical problems, such as the "Learning with Errors" (LWE) problem, which are difficult to solve even with quantum computers.
• Flexibility*: It supports advanced cryptographic tools like fully homomorphic encryption, enabling computations on encrypted data without decryption.
• Efficiency*: Lattice-based schemes can be competitive with or even outperform traditional methods like RSA or Diffie-Hellman in terms of performance.

For the Internet, lattice cryptography is being developed to provide efficient and practical protocols for tasks like key exchange, encryption, and authentication. These protocols aim to integrate seamlessly into existing Internet standards while maintaining high security. MCP is a security nightmare!

Don’t get me wrong — at Wexa, we see Model Context Protocol as the HTTP of the GenAI era. It’s the missing link to make AI assistants truly agentic and interoperable.

But here’s the reality:

MCP doesn’t govern security by default. -> Tool poisoning attacks are a cakewalk if you’re not explicitly validating or sanitizing inputs. Anyone can sneak in malicious instructions through tool descriptions or context — and the model will just obey.

Versioning is a mess. -> There’s no clear standard for how models or tools should handle different MCP versions. That means you risk breaking tools silently — or worse, running outdated logic with no warning.

Persistent context = persistent risk. -> If your AI coworker remembers things across sessions, what happens when the context itself is compromised or manipulated?

We’re bullish on MCP — it’s foundational to how we’re building secure, scalable AI agents inside Wexa.

But let’s be clear: if you’re using MCP in production today, you’re likely exposed unless you’ve already wrapped it in a tight security layer.

MCP is powerful. But don’t assume it’s safe out of the box.
