The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
GCLOUD_PROJECTGOOGLE_CLOUD_PROJECTGOOGLE_SERVICE_ACCOUNT_JSONis required (JSON string or file path).NANO_BANANA_AUTO_TASK_4Kruns 4K generations in task mode automatically to avoid client timeouts (set true to enable).NANO_BANANA_AUTO_TASK_TTL_MScontrols how long auto-task results remain available (ms). Set 0 for no expiry.NANO_BANANA_GCS_BUCKETis required if you want the server to upload local reference images to GCS.NANO_BANANA_GCS_PREFIXcontrols the object prefix for uploaded reference images (default: nano-banana/refs).NANO_BANANA_MODELNANO_BANANA_OUTPUT_DIRsets the local save root (defaults to ~/nano-banana-outputs). Relative outputDir values resolve under this path.NANO_BANANA_OUTPUT_GCS_BUCKETcontrols the GCS bucket for generated images (defaults to NANO_BANANA_GCS_BUCKET).NANO_BANANA_OUTPUT_GCS_PREFIXcontrols the object prefix for generated images (default: nano-banana/outputs).NANO_BANANA_PROGRESS_INTERVAL_MScontrols how often progress notifications are emitted (ms) to keep long MCP calls alive. Set 0 to disable.VERTEX_LOCATIONVERTEX_PROJECT_IDis optional if the service account JSON includes project_id.Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
2/2 tools missing one or more hints — nano_banana_generate_image (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); nano_banana_get_task (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.25.1 (high), @modelcontextprotocol/sdk@1.25.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
