AI agents call misp_export_hashes to retrieve information from Misp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool exports/retrieves file hash data from MISP for use in Host Intrusion Detection Systems. It is a read/export operation that queries and returns existing data without modifying or deleting anything. The blast radius is low as it only reads hash indicators.

Attacks that exploit this kind of access
Export file hashes from MISP for HIDS integration. It is categorised as a Read tool in the Misp MCP Server, which means it retrieves data without modifying state.
Register the Misp MCP server in PolicyLayer and add a rule for misp_export_hashes: 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 Misp. Nothing to install.
misp_export_hashes 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 misp_export_hashes 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 misp_export_hashes. 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.
misp_export_hashes is provided by the Misp MCP server (solomonneas/misp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
