Get multiple variables at once. Returns one line per variable.
AI agents call get_variables_bulk to retrieve information from ACM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves variable values from an ACM simulation session without altering state, executing code, or triggering external operations. It is a straightforward read operation with minimal blast radius—incorrect usage would only return wrong data, not cause damage or side effects.
From the tool's definition Tool name 'get_variables_bulk' and description 'Get multiple variables at once' indicate data retrieval with no modification. The verb 'Get' and absence of write/delete/execute language confirm read-only semantics.
Attacks that exploit this kind of access
Get multiple variables at once. Returns one line per variable. It is categorised as a Read tool in the ACM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ACM MCP Server MCP server in PolicyLayer and add a rule for get_variables_bulk: 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 ACM MCP Server. Nothing to install.
get_variables_bulk 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 get_variables_bulk 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 get_variables_bulk. 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.
get_variables_bulk is provided by the ACM MCP Server MCP server (pekosann/acm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
