Retrieve stored information by key.
AI agents call retrieve_data to retrieve information from Store MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and queries stored data from key-value storage. It performs a simple lookup operation with no capability to modify, delete, or execute code. It falls clearly into the Read category with low severity since retrieval operations have minimal blast radius even if misused.
From the tool's definition Tool name 'retrieve_data' and description 'Retrieve stored information by key' indicate data retrieval without modification. No side effects or state changes occur.
Attacks that exploit this kind of access
Retrieve stored information by key. It is categorised as a Read tool in the Store MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Store MCP Server MCP server in PolicyLayer and add a rule for retrieve_data: 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 Store MCP Server. Nothing to install.
retrieve_data 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 retrieve_data 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 retrieve_data. 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.
retrieve_data is provided by the Store MCP Server MCP server (mariano-cecowski/store_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
