# ContrastAPI (com.contrastcyber/api@1.36.2) > Source: > Published: 2026-08-24 22:31:56+00:00 [← Index](/leaderboard) # ContrastAPI 55 tools, 7 Resources, Sigma rules, email SPF/DMARC, MITRE, CVE/KEV, risk_score. No key. The current version, v1.36.2, was published to the official MCP registry on 2026-08-24. It is distributed as a hosted remote over streamable-http, filed under Email 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](/stats) put this record in context. ## Using ContrastAPI 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 2026-08-24). Contracts can change after screening, with no version bump. The gate pins ContrastAPI’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

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. ``` [Independent trust record for ContrastAPI](https://mcpindex.ai/server/com-contrastcyber-api) - screening verdict, registry provenance, and contract drift monitoring.
