Grafbase

Security checks across malware telemetry and agentic risk

Overview

This appears to be a legitimate Grafbase integration, but it gives an agent broad authenticated Grafbase mutation and proxy access without clear approval boundaries.

Install only if you are comfortable letting an agent operate on Grafbase through Membrane. Use least-privilege access, require explicit confirmation before mutations, deletes, proxy requests, secret changes, or billing changes, consider pinning or reviewing the Membrane CLI version before global installation, and revoke the Membrane/Grafbase connection when no longer needed.

Missing User Warnings

Medium
Confidence
89% confidence
Finding
The skill explicitly instructs the agent to send direct proxy requests to an external Grafbase API through Membrane, but it does not warn that arbitrary request paths, headers, and bodies may contain sensitive user or organizational data. In an agent setting, this increases the risk of unreviewed transmission of prompts, secrets, or private business data to a third-party service whenever prebuilt actions are bypassed.
