Defense-in-depth for MCP stdio servers: shell-injection guard, AST audit CLI, RCE blocking.

Defense-in-depth bundle for MCP stdio servers. Wraps with allowlist + sandbox + replay-detection, plus an AST audit CLI () that scans MCP server sources for unsanitized shell calls. Closes the Ox-Security MCP stdio-RCE class (200k vulnerable servers, May 2026 disclosure).

Inferred from the transports this listing declares (stdio). A client not listed here hasn’t been ruled out — it just isn’t something Forge can confirm.

Verification confirms publisher identity (repo ownership), not code safety. The security scan covers known CVEs and suspicious install scripts.

Statically extracted from the published packagev0.1.1 · 3mo ago

Read out of the source npm actually ships, at scan time. The package was never executed. Tools registered dynamically at runtime, or hidden inside bundled or minified code, can be missed — so this is a floor on the tool surface, not a complete census of it.

Tool names and descriptions are written by the publisher and shown verbatim as inert text. They are the strings an MCP client passes to a model, so Forge scans them for prompt-injection patterns — any finding appears with the security scan above. “Privileged” is a keyword match on the tool name, not an audit of what the tool does: a benign-sounding name can still do anything.
