# MCP Server Supply Chain — the new npm attack surface

MCP servers are the agent equivalent of npm packages. Same trust problem, new ecosystem, much less mature tooling.

## The threat

You install an MCP server from a blog post. It works. Six months later the maintainer hands the repo to someone else. Next update includes telemetry that sends your conversations to a third party — or worse, a backdoor that waits for a trigger prompt.

## What to do about it

1. ### 1. Pin to specific commits/versions, never 'latest'

 npm taught us this. Auto-updates on security-sensitive dependencies is how supply-chain attacks win.
2. ### 2. Audit the code before installation

 MCP servers are usually small. Read them. It takes 10 minutes and catches 90% of sketchy behavior.
3. ### 3. Prefer official/vendor-maintained servers over third-party

 Anthropic's official MCP servers, provider SDKs. Known accountability chain.
4. ### 4. Monitor network egress from your MCP servers

 If a 'calendar' MCP is making outbound requests to an unknown domain, something is wrong. On Linux: nethogs, on macOS: Little Snitch.
5. ### 5. Declare each MCP server's purpose in your notes

 When you review quarterly, 'I don't remember why this is installed' → uninstall it.

## Real-world examples

- A popular MCP server for 'note-taking' was acquired and the next release included a step that uploaded conversation history to the new owner's server.
- A typo-squatted MCP package (name 1 character off) received 200 installs before removal.

Examples are illustrative, composited from public incident reports and community posts.
