Get the value of a hash field
AI agents call redis_hget to retrieve information from Multi-Database MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The redis_hget command is a standard Redis hash field retrieval operation. It queries and returns data without side effects, making side effects non-existent. This is a read-only operation typical of the Read category. The blast radius is minimal since it only retrieves existing data without modifying, deleting, or executing arbitrary code. Low severity is appropriate for a simple data retrieval tool.
From the tool's definition Tool name 'redis_hget' and description 'Get the value of a hash field' indicate a retrieval operation with no modification or deletion of data.
Attacks that exploit this kind of access
Get the value of a hash field. It is categorised as a Read tool in the Multi-Database MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Multi-Database MCP Server MCP server in PolicyLayer and add a rule for redis_hget: 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 Multi-Database MCP Server. Nothing to install.
redis_hget 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_hget 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_hget. 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_hget is provided by the Multi-Database MCP Server MCP server (nam088/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
