AI agents call misp_list_galaxies 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 queries and retrieves a list of available galaxy definitions (threat intelligence taxonomies and reference data) from MISP. It performs no side effects, creates no data, executes no code, and causes no irreversible changes. It is purely informational, classifying it as a Read operation with low severity risk.
From the tool's definition Tool name 'misp_list_galaxies' and description 'List available MISP galaxies' indicate retrieval of reference data without modification or execution.
Attacks that exploit this kind of access
List available MISP galaxies (MITRE ATT&CK, threat actors, malware families, tools, etc.). 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_list_galaxies: 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_list_galaxies 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_list_galaxies 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_list_galaxies. 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_list_galaxies 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.
