Update: I've created a GitHub Issue proposing to address this problem.
Please help getting this fixed by adding your +1!
Here's the link: github.com/modelcontext...
Use the Strands SDK to build AI agents, easily integrating with existing MCP tools, selecting models from Bedrock, OpenAI, or Olama.
Itβs so easy, I felt so productive after just one hour :-)

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.
01.06.2025 18:09 β π 2 π 0 π¬ 1 π 0Bottom 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.
01.06.2025 18:09 β π 0 π 0 π¬ 1 π 0When 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
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.
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
Myth 3: "Trusted sources guarantee safety"
Even legitimate packages can be compromised through:
- Supply chain attacks
- Typosquatting
- Dependency confusion
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
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.
You've just told Claude to download and execute arbitrary code with your full user permissions.
01.06.2025 18:06 β π 1 π 0 π¬ 1 π 0Most 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:
{
"ππππππππππ": {
"ππππ-ππππ": {
"πππππππ": "πππ‘",
"ππππ": ["-π’", "@ππππ-πππ/πππ-ππππππ-ππππ"]
}
}
}
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!
