AI Security Harness: SAST, secrets, deps, containers, config & OWASP LLM. Scans locally.
The current version, v1.4.1, was published to the official MCP registry on 2026-09-17. It is distributed as gadriel on npm, filed under Docker & Containers by this index, and declares one environment variable. 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
uv tool install mcpindex-gate && mcpindex-config-wire
Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

That verdict was true at screening time (snapshot 2026-09-17). #
Contracts can change after screening, with no version bump. The gate pins Gadriel AI Security Harness’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.
