AI agents call read_memory to retrieve information from HackerMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from memory without modifying or deleting it, fitting the Read category. However, severity is elevated to 'medium' rather than 'low' because: (1) in a penetration testing context (HackerMCP server), memory access could expose sensitive information like credentials, keys, or exploit data; (2) the context of sibling tools (Nmap, Metasploit, msfconsole) suggests this server is designed for…
From the tool's definition Tool name is 'read_memory' and description states 'Read the memory.' The verb 'read' and lack of modification/deletion language clearly indicate retrieval without side effects.
Attacks that exploit this kind of access
Read the memory. It is categorised as a Read tool in the HackerMCP MCP Server, which means it retrieves data without modifying state.
Register the Hacker MCP server in PolicyLayer and add a rule for read_memory: 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 HackerMCP. Nothing to install.
read_memory 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 read_memory 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 read_memory. 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.
read_memory is provided by the Hacker MCP server (r3versein/hackermcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
