Check breach and data leak intelligence. Search known data breaches, leaked credentials databases, and exploit sources.
AI agents call breach_check to retrieve information from Oracle-42 DarkIntel MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and searches existing breach and leak intelligence databases. It performs lookups and queries ('Search known data breaches') without creating, modifying, deleting, or executing anything.
From the tool's definition Tool name 'breach_check' with description 'Search known data breaches, leaked credentials databases, and exploit sources' indicates querying/retrieving intelligence data with no modification or execution of side effects.
Attacks that exploit this kind of access
Check breach and data leak intelligence. Search known data breaches, leaked credentials databases, and exploit sources. It is categorised as a Read tool in the Oracle-42 DarkIntel MCP MCP Server, which means it retrieves data without modifying state.
Register the Oracle-42 DarkIntel MCP server in PolicyLayer and add a rule for breach_check: 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 Oracle-42 DarkIntel MCP. Nothing to install.
breach_check 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 breach_check 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 breach_check. 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.
breach_check is provided by the Oracle-42 DarkIntel MCP server (mintmas/oracle42-darkintel-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
