AI agents call download_text to retrieve information from Gallica without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'download_text' tool retrieves/downloads digitized document text from Gallica's digital library. This is a read operation with no side effects—it accesses existing data without creating, modifying, or deleting anything. The context of a public digital library and the clustering with other retrieval tools (search, snippets) confirms this is data access only.
From the tool's definition Tool name 'download_text' combined with sibling tools 'search_gallica', 'get_snippets', and 'advanced_search_gallica' all indicate read-only operations.

download_text is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the download_text rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for download_text. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
download_text is provided by the Gallica MCP server (nestordemeure/gallica-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
