Get value by key from Redis
AI agents call get to retrieve information from Helm Chart CLI without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation against Redis. It retrieves stored values by key without creating, modifying, deleting, or executing any operations. The blast radius is minimal—misuse would only expose cached data that is already accessible through proper Redis access.
From the tool's definition Tool name is 'get' and description states 'Get value by key from Redis', which retrieves data from a cache store with no side effects or modifications.
Attacks that exploit this kind of access
Get value by key from Redis. It is categorised as a Read tool in the Helm Chart CLI MCP Server, which means it retrieves data without modifying state.
Register the Helm Chart CLI MCP server in PolicyLayer and add a rule for get: 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 Helm Chart CLI. Nothing to install.
get 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 get 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 get. 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.
get is provided by the Helm Chart CLI MCP server (jeff-nasseri/servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
