Report vulnerabilities to support@agentstack.tech (preferred) or via GitHub Security Advisories on agentstacktech/cursor-plugin.
- Ships Markdown rules / skills / commands (guidance) plus local Node hooks.
- Connects Cursor to
https://agentstack.tech/mcpvia OAuth 2.1 Device Code (/agentstack-init). - Access tokens live in
~/.cursor/mcp.jsonundermcpServers.agentstack.headers. Refresh token:~/.cursor/agentstack-refresh(mode0600where supported). - MCP registration is user config only (no plugin-embedded MCP server since 0.4.16).
- Telemetry is opt-in (
agentstack.sendTelemetry: true). No prompt text is uploaded.
Bearer tokens in plaintext MCP config are a Cursor platform constraint. On shared OS accounts, clear MCP auth when done. Windows: file mode bits may be a no-op — rely on NTFS ACLs for your user profile.
Shell hook pre-shell-scan.mjs blocks obvious secret leaks in shell (e.g. raw API keys in curl headers).
