Search and retrieve books from the dataset. Supports filtering by title, author, genre, year, and pagination. Returns detailed book information including metadata. Requires active session for access.
AI agents call books_query to retrieve information from Session-Based Authenticated MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only operations on a books database. It retrieves and queries data with no side effects—no data is created, modified, deleted, or executed. The filtering and pagination are standard retrieval parameters. The requirement for active session authentication does not elevate the risk category, only the access control.
From the tool's definition Tool description explicitly states it is used to "Search and retrieve books from the dataset" with support for filtering and pagination.
Attacks that exploit this kind of access
Search and retrieve books from the dataset. Supports filtering by title, author, genre, year, and pagination. Returns detailed book information including metadata. Requires active session for access. It is categorised as a Read tool in the Session-Based Authenticated MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Session-Based Authenticated MCP Server MCP server in PolicyLayer and add a rule for books_query: 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 Session-Based Authenticated MCP Server. Nothing to install.
books_query 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 books_query 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 books_query. 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.
books_query is provided by the Session-Based Authenticated MCP Server MCP server (omiderfanmanesh/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
