CPG Knowledge Graph (io.github.greencore-solutions/cpg-knowledge-graph@1.2.4)

The CPG Knowledge Graph MCP server, version 1.2.4, was published to the official MCP registry on 2026-09-17 as a hosted remote over streamable-http, but its source repository is no longer publicly accessible, returning HTTP 404, according to the mcpindex index. mcpindex's semantic screen of the server's registry description returned a PARTIAL status with an advisory posture, finding no malicious instructions via static_description, while the deterministic conformance probe has not yet been run. The index warns that MCP tool contracts can change remotely with no version bump and that its gate pins each contract and holds calls when drift is detected.

← Index

Source repository no longer publicly accessible (HTTP 404). This may be deliberate: repositories are sometimes made private or relocated. Evidence.

The MCP for the beauty, cosmetics and personal care sector

The current version, v1.2.4, was published to the official MCP registry on 2026-09-17. It is distributed as a hosted remote over streamable-http, filed under Memory & RAG by this index. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Semantic screen found no manipulation pattern in the description. Conformance probe not yet run.

mcpindex.integrity.description passINFO evidence“No malicious instructions”via static_description

    • Semantic screen only - the deterministic conformance probe has not run on this server
    • Confidence is reported but not yet calibrated (v1)
    • Screen reads the tool description, not the live behavior
    • advisory
    • registry description only no input schema
    • screen model 8b
    • The registry listing (version, packages, links) changed after this screen ran - the description we assessed did not

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-09-17). #

Contracts can change after screening, with no version bump. The gate pins CPG Knowledge Graph’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.
