Rug pulls, tool shadowing, and tool poisoning prompt injection attacks, oh, my! @simon tackles #MCP (Model Context Protocol) prompt injection security problems. Hat tip: Jorge Bernal.

A Clear Intro to MCP (Model Context Protocol) with Code Examples

Excited to showcase our #MCP on @microcksio early prototype!

We're exploring the ability to turn all your #API contracts into MCP-enabled simulations so that you can check #AI agents' ability to reuse them as tools! Check our @claudeai101 #Anthopic demo

I built an #MCP for NOVA so you can use it as a guardrail for your AI system.

NOVA is a prompt pattern matching framework. It is primarily used for prompt hunting, similarly to how you use YARA for hunting files.

But NOVA can also be used as a guardrail to prevent malicious attempts and protect your LLM system based on your own NOVA rules.

I created a NOVA gateway using MCP. The model is instructed to always call the NOVA MCP first to validate the prompt before doing anything else.

If there is no match, the LLM continues execution.
If there is a match, execution stops and the user gets a notification that the request is blocked.

Every match is logged so you can track malicious attempts and review the security logs.

The Rug Pull: Silent Redefinition

Cross-Server Tool Shadowing

This week’s edition of my @linkedin newsletter shines a light on the impact of the Model Context Protocol (MCP) across multiple computing eras—leading right up to today.

We’ve arrived at a moment where loose coupling principles are cool (and super useful) again.

Naturally, there are some live demo nuggets in the post to help bring it all to life:

A quick preview of the Quarkus MCP CLI Adapter.
This is a demo on a feature that has just been merged on Quarkus MCP Server project.

You are probably sick of hearing/seeing #AI influencers talk about #MCP - finally started digging into the topic - see https://github.com/mdfranz/cheetsheetz/blob/main/ai/llm/mcp.md for some good (no hype) links.

Official #MCP Server for #GitHub

https://github.com/github/github-mcp-server

This is an #MCP Server that wraps various JVM diagnostic tools (CLI) such as jstat, jcmd, jps, adds a nice prompt to improve how they work, and exposes them.

At 50, if you haven't written your own mcp server, you've wasted your life. #mcp #llm

The whole #mcp ecosystem is pure magic, here's a quick demo seamlessly running the r2mcp server. Kudos to the plugin's author @dnakov #r2ai #reverseengineering #llm #claude if you want to try it out, just run “r2pm -Uci r2mcp" and add the json block described in the repo’s readme!
