Knostic

Knostic secures the AI agent supply chain inside the enterprise. Its platform discovers shadow AI, coding assistants, MCP servers and IDE extensions in use across an organization, then scans them for prompt injection, data exfiltration, secret and PII leakage, and destructive commands. Knostic runs AgentMesh, a public reputation and threat-intelligence service that continuously discovers, tracks and scans AI agent skills, Model Context Protocol servers, and VS Code / IDE marketplace extensions — roughly 80,500 skills, 4,800 MCP servers and 59,900 extensions as of July 2026 — and exposes that catalog with per-version scan verdicts through a REST API whose read endpoints answer anonymous callers. Knostic also ships a substantial open-source portfolio: AgentSonar (shadow-AI network detection), OpenAnt (LLM-based vulnerability discovery), MCP-Scanner, and security and telemetry plugins for OpenClaw agents.

Knostic publishes 1 API on the APIs.io network: AgentMesh API. Tagged areas include Company, Security, Artificial Intelligence, AI Agents, and Agent Security.

Knostic’s developer surface includes documentation, API reference, support, engineering blog, authentication, changelog, CLI, and 22 more developer resources.

  description: Reputation and threat intelligence for the AI agent supply chain. Search the AgentMesh catalog of agent skills,
    MCP servers and IDE extensions, read per-version security scan verdicts and risk evidence, look artifacts up by SHA-256
    content hash, and trigger on-demand scans. Catalog reads are served to anonymous callers at a reduced tier; scan operations
    require an API key and are limited to 30 scans per key per day.
