Could you build this?
No Building robust OS-level sandboxing, static code analysis for security policy drafting, and intercepting JSON-RPC protocols requires deep systems programming and security engineering.
What it would actually take: This requires systems languages like Rust/Go leveraging platform-specific sandboxing primitives (such as Landlock, seccomp-bpf on Linux, or sandbox-exec/Seatbelt on macOS) combined with a custom static analysis AST parser to infer capabilities from MCP code. Intercepting JSON-RPC streams with low-latency policy enforcement demands rigorous kernel-level and systems security knowledge.
