I build and ship small products across consumer apps, developer tools, and applied AI systems. Some I open source.

Product Manager at Google.

mcp-preflight (open source)
Preflight inspection for MCP servers before you trust them.

• Open-source CLI published on PyPI
• Shows what an MCP server exposes (tools, resources, prompts) without executing anything
• Useful when the client is an LLM, where risk depends on exposed capabilities, not just user intent

It’s a bit like running ls -la on an MCP server: not a security guarantee, just basic visibility.
