SigmaShake Guardrails

SigmaShake Guardrails is the hosted control plane for Grok Bot and Cursor. It evaluates AI tool calls against SSG rules (ALLOW/DENY/ASK/FORCE/LOG/SHADOW) and provides honest-agent safeguards — integration-dependent guardrails, not a sandbox.

What it does

Call sigmashake_eval before a tool runs. Honor ALLOW, DENY, ASK, FORCE, LOG, and SHADOW. If eval is unavailable, fail closed on destructive, secret, irreversible, or rule-mutation actions. Draft rule text in chat only — never create, edit, delete, or sync live SSG rules from this plugin.

Local Cursor on your OS can still use stdio ssg mcp-server. Grok Bot cannot: connectors run on the bot computer, so this landing ships the remote HTTPS MCP.
