Analysis summary

Next.js DevTools MCP is an officially published MCP server from Vercel. Anomity scores its risk at 10 out of 100 (low).

Vercel's MCP server for Next.js development exposes build and runtime diagnostics to an agent — route information, build errors, and framework-specific guidance — so an assistant debugging a Next.js app works from the framework's own view rather than from guesses.

It reads the local project and reaches the network, so it declares filesystem reads and outbound network access. Risk is low relative to the deployment and database servers in this list; the main consideration is scope, since a tool that reads your project directory reads whatever is in it, including any `.env` files that happen to be sitting there.

Why this entry scored 10 out of 100

Capabilities

Every capability the entry declares, with the security implication of each.

  • filesystem:read Filesystem read
    Can read files on the host system. Used for context, indexing, or analysis.
  • network:outbound Outbound network
    Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access.
