Get type of a Redis key
AI agents call redis_type to retrieve information from Mcp Database without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads the type of an existing Redis key (string, list, set, hash, etc.). It has no side effects and cannot modify or delete data. Misuse potential is minimal — at worst an agent learns the data type of a key.
From the tool's definition 'Get type of a Redis key' — purely retrieves metadata about a key without modifying any data
Attacks that exploit this kind of access
Get type of a Redis key. It is categorised as a Read tool in the Mcp Database MCP Server, which means it retrieves data without modifying state.
Register the Mcp Database MCP server in PolicyLayer and add a rule for redis_type: 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 Database. Nothing to install.
redis_type 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 redis_type 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 redis_type. 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.
redis_type is provided by the Mcp Database MCP server (nam088/mcp-database-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
