AI agents call book_get_chapters to retrieve information from Legado without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get' prefix and contextual patterns from related tools indicate this retrieves chapter data from books without side effects. Despite the empty description lowering confidence slightly, the consistent naming pattern across the Legado server's Read operations (book_get_*) makes Read the appropriate classification.
From the tool's definition Tool name 'book_get_chapters' indicates data retrieval with 'get' verb. Sibling tools like 'book_get_content', 'book_get_cover', and 'book_get_image' establish a pattern of Read operations on this server.

PolicyLayer is an MCP gateway — it sits between your AI agents and Legado, and nothing reaches the server without passing your rules. This is the rule we recommend for book_get_chapters:
{
"version": "1",
"default": "deny",
"tools": {
"book_get_chapters": {}
}
}book_get_chapters is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

book_get_chapters. It is categorised as a Read tool in the Legado MCP Server, which means it retrieves data without modifying state.
Register the Legado MCP server in PolicyLayer and add a rule for book_get_chapters: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Legado. Nothing to install.

Yes. Add a rate_limit block to the book_get_chapters 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 book_get_chapters. 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.
book_get_chapters is provided by the Legado MCP server (joestar817/legado-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Legado, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
