The N x M integration problem framing is exactly why MCP took off, but the security side deserves equal space. I evaluate every MCP server my agents touch against a short checklist, tool descriptions that overstate scope, missing rate limits, and endpoints that accept arbitrary paths, because a malicious server can steer the agent through its own tool descriptions. I wrote my full checklist here: [kartiknvjk.hashnode.dev/how-i-evaluate-mcp-server…](https://kartiknvjk.hashnode.dev/how-i-evaluate-mcp-servers-for-security-before-i-trust-them) . How do you sandbox servers you did not write yourself?

Velocity gains from AI vanish when review debt piles up. I cap open AI pull requests so the team finishes one batch before the next wave lands.

That's definitely a valid concern!
