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.

Cody Enterprise 3.0 is Sourcegraph's AI coding assistant built for large engineering organizations, extending context retrieval across unlimited repositories simultaneously so developers get answers that understand the full codebase. It adds SOC 2-compliant audit logging for every AI interaction, satisfying the compliance requirements that block enterprise AI adoption. Bring-your-own-model support lets teams swap in their preferred LLM without losing the context layer.
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.”
“The primitive here is honest and specific: a context retrieval layer that indexes across unlimited repos and pipes relevant code into whatever LLM you bring. That's a real problem — the moment your codebase spans more than one repo, GitHub Copilot and Cursor both go partially blind. The BYOM configuration is the right DX bet; it puts complexity in config where it belongs and lets the context engine be the actual product rather than a forced model subscription. The moment of truth is asking a question that spans three repos — if that actually works without hallucinating package boundaries, this earns its enterprise price tag. What I want to see is the indexing pipeline documented: how fresh is the context, what's the staleness model, and does it handle monorepos differently than polyrepos? Those aren't marketing questions, they're the whole product.”
“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 direct competitors are GitHub Copilot Enterprise and Cursor with codebase indexing — and neither of them has Sourcegraph's decade of code search infrastructure underneath. That history is the actual moat, not the AI wrapper on top. Where this breaks: organizations with highly fragmented access controls across repos, where the context retrieval either over-fetches (security problem) or gets permission-gated into uselessness. The SOC 2 audit logs are table stakes for any enterprise deal in 2026, so calling that a feature is a bit rich — but shipping it before competitors formalized it matters. What kills this in 12 months: GitHub ships deeper Copilot Enterprise context natively and the org that was already paying for GitHub Enterprise doesn't want a second line item. Sourcegraph survives that only if the context quality gap stays wide enough to justify the cost.”
“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.”
“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.”
“The buyer is the VP of Engineering or CISO at a company with 200+ engineers across multiple repos — this is a clear, checkbook-holding persona, and SOC 2 audit logs are specifically the procurement unlock that moves deals out of legal limbo. That's a real wedge. The BYOM configuration is smart revenue-defensibility: Sourcegraph becomes the context layer that persists regardless of which model wins the next benchmark cycle, insulating them from the commodity model price war. The risk is the expand story — once they land an enterprise, what does deeper adoption look like? If it's just more seats, they're a seat-count business, and seat-count businesses get squeezed when headcount freezes. The specific decision that makes this viable is owning the index, not the model — the index is sticky, the model is not.”
“The job-to-be-done is clean: get an accurate, context-aware answer about code that lives in more than one repository without switching tools or copy-pasting context manually. That's one job, no 'and.' Onboarding for enterprise is always an IT/procurement journey, not a 2-minute trial, so I won't penalize that — but the individual free tier needs to get a solo dev to a cross-repo answer in under 5 minutes or it never seeds the enterprise deals. The product opinion is strong: Sourcegraph has committed to the context layer being the product, which means they're not trying to win on model quality. That's the right call given their history. The gap is that 'unlimited repositories' as a marketing claim needs to be stress-tested publicly — if there's a practical ceiling at 50 repos or 10M LOC, that needs to be in the docs, not discovered during a pilot.”
