MCP config install lure — email asks you to paste hostile JSON into ~/.cursor/mcp.json / claude_desktop_config (2026 AI-tool supply chain attack)
mcp-server-config-install-lure
What this tier means
High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.
How Gorganizer detects this
Email lures the recipient into pasting hostile JSON configuration into a local AI-coding-tool Model Context Protocol (MCP) config file (~/.cursor/mcp.json, claude_desktop_config.json, ~/.continue/config.json, ~/.cline/config, Windsurf / Codeium config paths). Once the config is saved and the tool restarts, the attacker has a local subprocess running with the user's privileges and can read conversation context, exfiltrate environment tokens, and execute arbitrary shell commands. Fires when the body references MCP configuration (mcpServers / model-context-protocol / mcp.json) AND either a well-known config path or a JSON block with the MCP shape (command+args for stdio transport, or url+sse for remote transport), from a sender that is NOT a known AI-tool vendor (Anthropic, Cursor, Continue, Sourcegraph, Codeium, Windsurf, Cline, ModelContextProtocol.io, OpenAI). Replies (In-Reply-To present) and newsletters (List-Unsubscribe present) are exempted because colleague config-sharing and developer-newsletter articles are legitimate contexts.
False-positive guard
Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a threat-tier signal — it adds a strong contribution to the trash score. The full pipeline still requires convergence across multiple modules + a margin over the safety floor before deletion happens, and Gmail's trash (30-day recovery) is always used — never permanent delete.
About the scoring engine
Gorganizer's scoring engine emits over 1,800 signals across six modules — headers, sender, subject, body, attachments, and structural metadata. Every email is scored by every module independently; the final verdict requires multiple modules to agree and the trash score to beat the safety floor by a margin.
Sacred safety guards — never delete starred emails, replies, calendar invites, receipts/invoices, or attachments — apply unconditionally regardless of any signal.
