Comprehensive reconnaissance using all available sources and features. Takes longer but provides the most complete results.
AI agents call theharvester_full_recon to retrieve information from theHarvester MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite being OSINT reconnaissance (often sensitive from a privacy/legal perspective), the tool itself only retrieves and queries public data sources without side effects. The blast radius is medium because reconnaissance can enable follow-on attacks and may violate terms of service or privacy laws depending on usage, but the tool itself is passive read-only.
From the tool's definition Tool performs 'domain reconnaissance' including 'email harvesting, subdomain discovery, DNS brute force, and Shodan integration' — all information-gathering operations with no stated capability to modify, delete, execute code, or perform financial…
Attacks that exploit this kind of access
Comprehensive reconnaissance using all available sources and features. Takes longer but provides the most complete results. It is categorised as a Read tool in the theHarvester MCP Server MCP Server, which means it retrieves data without modifying state.
Register the theHarvester MCP Server MCP server in PolicyLayer and add a rule for theharvester_full_recon: 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 theHarvester MCP Server. Nothing to install.
theharvester_full_recon 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 theharvester_full_recon 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 theharvester_full_recon. 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.
theharvester_full_recon is provided by the theHarvester MCP Server MCP server (schwarztim/sec-theharvester-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
