# Liongard (io.github.wyre-technology/liongard-mcp@2.3.7) > Source: > Published: 2026-08-20 22:30:08+00:00 [← Index](/leaderboard) # Liongard MCP server for Liongard — inspectors, environments, metrics, detections, and timeline data. The current version, v2.3.7, was published to the official MCP registry on 2026-08-20. It is distributed as the Docker image ghcr.io/wyre-technology/liongard-mcp:v2.3.7, filed under Other by this index, and declares 5 environment variables. 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](/stats) put this record in context. ## Using Liongard in Claude, Cursor, Gemini CLI, Cline, or Zed? 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 ``` [method](/methodology) Semantic screen found no manipulation pattern in the description.

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. Own this server? [Screen its description →](/screen) ## That verdict was true at screening time (snapshot 2026-08-20). Contracts can change after screening, with no version bump. The gate pins Liongard’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.
