Nano Banana MCP server — Google Gemini image generation and editing via Model Context Protocol
What the code does
We read the source, 21 h ago · rules 995398eba69f
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
const fullPath = path.join(stagingDir, filename);
const child = spawn(process.execPath, [script], {
if (isUnder(resolvedAbs, sshDir)) return { hit: true, reason: '~/.ssh/** is sensitive' };
<script src="https://appsforoffice.microsoft.com/lib/1.1/hosted/office.js"></script>
const entries = fs.readdirSync(workspacePath, { withFileTypes: true });
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
