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 API contracts indexed 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 pricing, documentation, API reference, support, engineering blog, authentication, changelog, and 28 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

6 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Governance scores 4.5 — up to +11.5 composite points
Contract Quality scores 56.6 — up to +10.9 composite points
Developer Ergonomics scores 66.7 — up to +6.7 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/knostic/apis.yml: open an issue on github.com/api-evangelist/knostic to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Agent Skills (SKILL.md packages)	distribution	9.6 (thin)	-	1

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
