WHAT IT DOES

What index_library_pdfs does on Metis Public Health

AI agents use index_library_pdfs to create or update resources in Metis Public Health, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Metis Public Health environment.

RISK

Why index_library_pdfs is rated Medium

The tool name strongly suggests it indexes PDF files from a library — a Write operation that creates or modifies an index/database of documents on the user's machine. The description is empty, so exact behavior is uncertain. Indexing is reversible (the index can be rebuilt or deleted), placing it in Write rather than Destructive.

From the tool's definition Tool name 'index_library_pdfs' and server description: 'answers from the user's own indexed PDF library with page-level citations' and 'keeps all data on the user's machine'

RECOMMENDED RULE

The rule that runs index_library_pdfs safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Metis Public Health, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For index_library_pdfs, this is the rule to start with:

index_library_pdfs Rate-limited

index_library_pdfs stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
