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 4 APIs on the APIs.io network, including extensions API, mcp API, scans API, and 1 more. 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 24 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/knostic: open an issue to ask a question, or submit a pull request to add artifacts.
