Supercharging DevOps with MCP (Without Opening a Security Hole)
summary
MCP (Model Context Protocol) lets LLMs call real tools via a client/server JSON-RPC pattern so models can query Grafana, trigger CI/CD, read Sentry, create GitHub branches, run kubectl, access databases or control Playwright-driven browsers. MCP servers advertise capabilities and return structured context; common attacks include prompt injection, tool poisoning and shadowing (examples: GitHub leak, mocked token exfiltration), and claims include ~75% of code pushed by AI and Entropic detecting ~88% of injections. Defenses: pin versions and whitelist MCPs, enforce read‑only for sensitive systems, and use proxy sanitizers.
