redis_memory

Analyze Redis memory usage — used, peak, fragmentation, big keys, and memory doctor recommendations

Part of the Sentinal MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call redis_memory to retrieve information from Sentinal without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though redis_memory only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the redis_memory tool do? +

Analyze Redis memory usage — used, peak, fragmentation, big keys, and memory doctor recommendations. It is categorised as a Read tool in the Sentinal MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on redis_memory? +

Add a rule in your Intercept YAML policy under the tools section for redis_memory. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Sentinal MCP server.

What risk level is redis_memory? +

redis_memory is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit redis_memory? +

Yes. Add a rate_limit block to the redis_memory rule in your Intercept 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.

How do I block redis_memory completely? +

Set action: deny in the Intercept policy for redis_memory. 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.

What MCP server provides redis_memory? +

redis_memory is provided by the Sentinal MCP server (@md-musaraf/sentinal-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
