Search for information about a specific paper across all topic directories.
AI agents call extract_info to retrieve information from 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 a search/query operation to retrieve information about papers. It has no side effects, does not modify data, execute code, delete content, or involve financial transactions. The verb 'search' and the retrieval-focused purpose clearly indicate a Read category classification. Low severity because misuse would only expose existing information without enabling further harmful actions.
From the tool's definition Tool description states it 'Search for information about a specific paper' - a retrieval operation with no modification or execution capability.
Attacks that exploit this kind of access
Search for information about a specific paper across all topic directories. It is categorised as a Read tool in the MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Server MCP server in PolicyLayer and add a rule for extract_info: 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 MCP Server. Nothing to install.
extract_info 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 extract_info 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 extract_info. 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.
extract_info is provided by the MCP Server MCP server (izzanzahrial/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
