AI agents call ism_get to retrieve information from Ism without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve ISM control information without modification. The suffix '_get' is universally associated with read operations in REST and programming conventions. The broader context of an information security manual query layer, combined with sibling read-only tools, strongly suggests ism_get retrieves control data rather than modifies, executes, or deletes.
From the tool's definition Tool name 'ism_get' follows standard naming convention for retrieval operations. Context shows the server provides a 'query layer' for discovering and interrogating ISM controls.
Attacks that exploit this kind of access
ism_get. It is categorised as a Read tool in the Ism MCP Server, which means it retrieves data without modifying state.
Register the Ism MCP server in PolicyLayer and add a rule for ism_get: 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 Ism. Nothing to install.
ism_get 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 ism_get 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 ism_get. 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.
ism_get is provided by the Ism MCP server (samueldudley/ism-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
