Security flags foundOur static scan found signals worth reviewing before you trust this with an agent. See exactly what, per check, below.
Install-time hooks & dependenciesno flags
Code that runs when you install it, before you ever call a tool.

Prompt-injection passthroughno flags
Whether it pipes untrusted external content back as agent instructions.
Permission scope breadthno flags
How much access it asks for versus what its job needs.
How to read this: these are static checks over the source at a point in time. They catch the patterns above, not everything. Absence of a flag is not absence of danger, and a tool that runs cleanly can still behave differently once installed. We do not call any tool simply "safe". Runtime-behavior checks are the next layer we are adding.
