AI agents call misp_correlate 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 retrieves and queries correlations within MISP threat intelligence data. It searches across events to find relationships but does not create, modify, delete, or execute any code or external operations. It is a straightforward read operation with no side effects or risk of data mutation.
From the tool's definition Tool name 'misp_correlate' and description 'Find correlations for a specific observable value across all MISP events' indicate querying/searching existing data with no modification or deletion.
Attacks that exploit this kind of access
Find correlations for a specific observable value across all MISP events. 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_correlate: 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_correlate 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_correlate 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_correlate. 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_correlate 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.
