Use the Strands SDK to build AI agents, easily integrating with existing MCP tools, selecting models from Bedrock, OpenAI, or Olama. It’s so easy, I felt so productive after just one hour :-) Follow this four-part series of tutorials by @dtraub.bsky.social community.aws/content/2xP1...

If you're deploying MCP in production, treat it like you're installing random software from the internet. Because - again - that's exactly what you're doing.

That "productivity tool" that helps manage your GitHub repos? It can also read your SSH keys, access your cloud credentials, and exfiltrate your entire codebase.

Dennis Traub @dtraub.bsky.social · 01/06/2025
Bottom line: When your AI assistant in Claude or Cursor connects to an MCP server via stdio, you're essentially giving that server the same permissions you have on your system.
100
Dennis Traub @dtraub.bsky.social · 01/06/2025
When you run `npx -y @some-org/mcp-server-tool`, you're: - Executing arbitrary code with your permissions - Trusting an unvetted supply chain - Granting network and filesystem access - Bypassing traditional security controls
100
Dennis Traub @dtraub.bsky.social · 01/06/2025
MCP's stdio transport was designed for developer convenience, not enterprise security. Unlike remote MCP servers that run on external infrastructure, stdio servers execute directly on your local machine where you're running Claude Desktop, Cursor, or other MCP clients.
100
Dennis Traub @dtraub.bsky.social · 01/06/2025
What MCP security actually requires: - Treating every server as potential malware - Implementing application-level sandboxing - Auditing every tool description for hidden instructions - Zero-trust model for all MCP interactions
130
Dennis Traub @dtraub.bsky.social · 01/06/2025
Myth 3: "Trusted sources guarantee safety" Even legitimate packages can be compromised through: - Supply chain attacks - Typosquatting - Dependency confusion
100
Dennis Traub @dtraub.bsky.social · 01/06/2025
Myth 2: "Human oversight prevents attacks" Here's why this is a faulty belief: - Hidden Unicode instructions bypass visual inspection - Users lack expertise to spot malicious command modifications - Consent fatigue leads to automatic approval
100
Dennis Traub @dtraub.bsky.social · 01/06/2025
Here are 3 myths about MCP you need to immediately stop believing: Myth 1: "MCP servers are just APIs" Unlike REST APIs, stdio MCP servers execute on your local machine with full system permissions. They're not services - they're programs running alongside your AI assistant.
110
Dennis Traub @dtraub.bsky.social · 01/06/2025
You've just told Claude to download and execute arbitrary code with your full user permissions.
110
Dennis Traub @dtraub.bsky.social · 01/06/2025
Most MCP servers use stdio mode, which means the server runs locally on your machine, not remotely. Here's what happens when you add this to your Claude Desktop config: { "𝚖𝚌𝚙𝚂𝚎𝚛𝚟𝚎𝚛𝚜": { "𝚜𝚘𝚖𝚎-𝚝𝚘𝚘𝚕": { "𝚌𝚘𝚖𝚖𝚊𝚗𝚍": "𝚗𝚙𝚡", "𝚊𝚛𝚐𝚜": ["-𝚢", "@𝚜𝚘𝚖𝚎-𝚘𝚛𝚐/𝚖𝚌𝚙-𝚜𝚎𝚛𝚟𝚎𝚛-𝚝𝚘𝚘𝚕"] } } }
100
Dennis Traub @dtraub.bsky.social · 01/06/2025
Stop treating MCP servers like browser extensions. Start treating them like you're downloading random executables from the internet. Because when you add an MCP server to Claude Desktop or Cursor IDE, that's exactly what you're doing!
