AI agents call scanKeys to retrieve information from Miadi without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs pattern-based key enumeration against Redis, which is a read-only operation with no side effects. It retrieves metadata about keys but does not create, modify, delete, or execute code. The blast radius of misuse is limited to information disclosure about what keys exist in Redis.
From the tool's definition Tool name 'scanKeys' and description 'Scan Redis keys using pattern matching' indicate a query/inspection operation. The verb 'scan' combined with 'pattern matching' describes retrieving or enumerating keys without modifying data.
Attacks that exploit this kind of access
Scan Redis keys using pattern matching. It is categorised as a Read tool in the Miadi MCP Server, which means it retrieves data without modifying state.
Register the Miadi MCP server in PolicyLayer and add a rule for scanKeys: 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 Miadi. Nothing to install.
scanKeys 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 scanKeys 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 scanKeys. 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.
scanKeys is provided by the Miadi MCP server (miadi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
