Get range of members from a sorted set
AI agents call redis_zrange 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.
The tool retrieves a range of members from a Redis sorted set without modifying any data. This is a read-only operation equivalent to the Redis ZRANGE command.

Attacks that exploit this kind of access
Get range of members from a sorted set. 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_zrange: 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_zrange 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_zrange 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_zrange. 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_zrange 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.
