Ship faster with AI. Keep your secrets and your codebase intact.

Engineers run Cursor, Claude Code, and Copilot all day. Those agents install packages, call MCP servers, and write the code you ship. Knostic secures that loop without slowing it down.

Kirin Security Alert

Critical risk detected

Hallucinated package installed. Please review package...

The code is written before anyone reviews the plan.

An agent asked for an endpoint produces one in seconds, with whatever packages, permissions, and queries it chose. Hallucinated dependencies, missing auth checks, and leaked API keys slip in at the speed of generation. Knostic makes the agent follow your rules before it writes a line.

How Knostic fits the engineering workflow

Secure by default

Before Knostic

Enforcement off, no CLAUDE.md. The agent goes straight to code: no permission check on the route, the caller's id concatenated into SQL, a malicious package and a vulnerable one in the install step. It ships anyway.

After Knostic

Enforcement on. The agent reads your coding rules, writes a STRIDE threat model, then codes: auth on the route, parameterised queries, ownership checked. The malicious install is blocked and the vulnerable one patched.

Packages, skills, and extensions

Before Knostic

The agent pulls a package that does not exist on the registry, or installs an extension that reuses known malicious code. Nothing in the diff shows it.

After Knostic

Every package, skill, MCP server, and extension is checked against AgentMesh and blocked if dangerous, before the install completes.

Guardrails on actions

Before Knostic

An agent cleaning up test data runs the command against production. It worked, so it reports success.

After Knostic

Destructive commands are denied inline with a clear reason, and the developer can proceed the safe way.

Key capabilities

Hallucinated and malicious package detection

Catches packages that do not exist, are typosquats, or carry known malicious code before install.

Secure-coding enforcement

Agents follow your CLAUDE.md and rules files, threat-model first, and apply your patterns for auth, input handling, and data access.

Secret detection

API keys and credentials in prompts, context, and output are caught and blocked or redacted.

MCP server validation

Connections to misconfigured or unapproved MCP servers are blocked in real time.

Autonomous vulnerability discovery

OpenAnt finds real, exploitable vulnerabilities in your codebase and proposes fixes, with false positives filtered out.

No workflow friction

Policy is applied inside the agent with actionable fixes. No separate gate, no waiting on a scan.

Frequently asked questions

Cursor, Claude Code, GitHub Copilot, Windsurf, Codex, JetBrains, Devin Desktop, and Gemini CLI.

No. Kirin runs in the background of the agent and only interrupts when something would violate policy, with the reason and the safe alternative.

Install steps are checked against the registry and AgentMesh verdicts. A package that does not exist, is a typosquat, or is known malicious is blocked before it lands.

Knostic's open-source, LLM-powered vulnerability discovery tool. It finds exploitable vulnerabilities, verifies them, and eliminates the false positives that waste engineering time.
