Best Security MCP servers
Security MCP servers let an agent find and reason about vulnerabilities directly in the code it's writing — static analysis, dependency and license scanning, secret detection, and container checks. The payoff is shifting security left into the editing loop: an agent can scan a diff it just generated, explain why a finding is exploitable, and propose a fix before the code ever reaches CI. When choosing, look at coverage (SAST for your own code, SCA for dependencies, IaC and container scanning) and at where analysis runs — locally over stdio for fast, private feedback, versus a platform that correlates findings across your whole org. Most run as local CLI-backed servers with an optional token to sync with a hosted dashboard.
