AI tool scanner MCP Bastion highlights code review blind spots

By PulseAugur Editorial · [1 sources] ·

MCP Bastion, an open-source scanner for Model Context Protocol (MCP) servers and AI-agent tools, was used to demonstrate how subtle changes in tool descriptions can be missed during code reviews. The scanner found that altering a single sentence in the description of the `get_uptime` tool, from promising uptime in seconds to including the deployment region, triggered a HIGH finding when scanned against an approved version. This highlights a potential vulnerability where changes to tool advertisements, even if seemingly minor, might not be caught by human reviewers but could be flagged by automated tools like MCP Bastion.
