AI agents call misp_list_object_templates 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 is a read-only operation that queries and returns a list of available object templates from MISP. It has no side effects, does not modify data, does not execute code or commands, and does not delete or create resources. The blast radius of misuse is minimal—an AI agent listing templates cannot cause harm.
From the tool's definition Tool name 'misp_list_object_templates' and description 'List available MISP object templates' indicate a retrieval/query operation that returns metadata about available templates without modifying or executing anything.
Attacks that exploit this kind of access
List available MISP object templates (file, domain-ip, email, network-connection, 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_object_templates: 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_object_templates 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_object_templates 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_object_templates. 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_object_templates 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.
