Why book_search is rated Low
This is a pure data retrieval tool that queries a public-domain book catalog and returns structured metadata. It has no capability to create, modify, delete, or execute operations. The search functionality with filters is read-only querying. The blast radius of misuse is minimal—an agent could only retrieve unwanted book information but cannot cause any system damage or data loss.
From the tool's definition Tool performs a search operation across the Project Gutenberg catalog, returning book metadata (Gutenberg id, title, author(s), language, download count) with no modification or deletion capability.
Attacks that exploit this kind of access
The rule that runs book_search safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Livedatalink, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For book_search, this is the rule to start with:
book_search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Livedatalink, apply this rule, and every book_search call is checked against it from then on.
