List the stores Silicon supports, optionally filtered by region. Free — does not consume quota.
AI agents call list_retailers to retrieve information from Silicon MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about supported retailers without modifying, executing external operations, or committing resources. It is a straightforward listing/query operation that an AI agent can safely call for informational purposes. The low severity reflects minimal blast radius—the worst outcome is receiving stale or incomplete retailer information.
From the tool's definition Tool name 'list_retailers' and description 'List the stores Silicon supports' indicate a retrieval operation with no side effects. The phrase 'optionally filtered by region' confirms this is a query/filtering action only.
Attacks that exploit this kind of access
List the stores Silicon supports, optionally filtered by region. Free — does not consume quota. It is categorised as a Read tool in the Silicon MCP MCP Server, which means it retrieves data without modifying state.
Register the Silicon MCP server in PolicyLayer and add a rule for list_retailers: 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 Silicon MCP. Nothing to install.
list_retailers 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 list_retailers 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 list_retailers. 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.
list_retailers is provided by the Silicon MCP server (silicon-store/silicon-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
