Lilith-Zero is a security runtime written in Rust that sits between your AI agent and its MCP tool servers, enforcing deterministic access control policies and blocking data exfiltration attempts before they reach the wire. It targets what it calls the "Lethal Trifecta"—the attack chain of accessing private data, incorporating untrusted content, then exfiltrating the combination—and blocks all three steps automatically. The technical stack is serious: fail-closed architecture (default-deny everything), dynamic taint tracking that marks sensitive data with session-bound tags, cryptographically signed HMAC-SHA256 audit logs, and formal verification via the Kani prover plus cargo-fuzz fuzzing infrastructure. Performance overhead is under 0.5ms at p50 with a 4MB memory footprint. It ships as a pip-installable Python SDK that auto-discovers and wraps its Rust binary. This is a Show HN project that appeared on Hacker News today and is currently at version 0.1.3 with 260 commits—small community (15 stars) but deeply engineered. As AI agents gain write access to filesystems, databases, and APIs, the absence of a policy enforcement layer becomes a serious liability. Lilith-Zero is one of the first open-source tools to treat this problem with the rigor it deserves.

Turbolite is a custom SQLite VFS (Virtual File System) that serves queries directly from S3-compatible storage with sub-250ms cold start latency, even for JOINs across tables. It eliminates the need to download entire databases locally, making SQLite viable for serverless and edge deployments.
Reviewer scorecard
“The Kani formal verification and cargo-fuzz integration tell me this isn't just a vanity security project—it's been engineered to actually be correct. Sub-millisecond overhead means there's no reason not to run this in front of every MCP agent deployment. 15 stars seems like an embarrassing undercount given what this does.”
“Sub-250ms JOINs from cold S3 reads is genuinely impressive. This solves the biggest pain point of SQLite in serverless — you no longer need to ship the whole DB file. The VFS approach is the right abstraction level. I would use this for analytics dashboards today.”
“The claims are impressive but 15 GitHub stars and one maintainer is not a security tool I'd deploy in production. Security tools require adversarial testing by the community over time—not just formal verification. The fail-closed design is correct philosophically, but I'd want to see 6 months of battle-testing and independent security audits before trusting it with real agent deployments.”
“The benchmarks look real and the approach is sound — page-level fetching from S3 with smart caching. The caveat is this is read-only, so it is not replacing your primary database. But for serving pre-built analytical SQLite databases from cheap storage? Hard to beat.”
“This is the tool that enterprise security teams will demand before they let any AI agent touch production systems. The taint tracking model is particularly elegant—once data is tagged as sensitive, it can't flow to untrusted destinations regardless of what the LLM decides to do. This is the kind of principled security primitive the agentic ecosystem desperately needs.”
“SQLite is eating the database world from the edges inward. Turbolite removes the last real objection — file size and distribution. Pair this with Litestream for writes and you have a full database stack with zero servers.”
“Way too deep in the Rust/MCP security weeds for me to evaluate or use. This is infrastructure for enterprise AI security teams—not something a content creator or indie builder will interact with directly. Worth knowing it exists; not something I'll try this week.”
