List all values for a specification field
AI agents call vtex_list_specification_field_values to retrieve information from MCP VTEX Server 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 specification field values from the VTEX catalog. It performs a read-only operation that does not create, modify, delete, or execute any external processes. The blast radius of misuse is minimal, as an AI agent could at worst enumerate product specifications, which is typically non-sensitive catalog metadata.
From the tool's definition Tool name contains 'list' and description states 'List all values for a specification field' — a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access

Register the MCP VTEX Server MCP server in PolicyLayer and add a rule for vtex_list_specification_field_values: 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 MCP VTEX Server. Nothing to install.
vtex_list_specification_field_values 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 vtex_list_specification_field_values 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 vtex_list_specification_field_values. 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.
vtex_list_specification_field_values is provided by the MCP VTEX Server MCP server (leosepulveda/mcp-vtex). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
