AI agents call misp_list_sharing_groups 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 returns information about MISP sharing groups to enable visibility into available distribution channels. It has no side effects, does not modify data, execute commands, delete records, or commit financial transactions. The operation is informational only, making it a Read category risk with low severity since the blast radius of misuse is limited to disclosure of sharing group metadata.
From the tool's definition Tool name contains 'list' and description states 'List MISP sharing groups' — a pure retrieval operation with no modification, deletion, or execution of code.

misp_list_sharing_groups 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_sharing_groups 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.
