Delete a JSON value from Redis at a given path. Args: name: The Redis key where the JSON document is stored. path: The JSON path to delete (default: root '$'). Returns: A success message or an error message.
AI agents call json_del to permanently remove resources in Redis MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool deletes data without the ability to undo the operation. While the deletion targets a specific JSON path within a Redis key (rather than the entire key), it still results in permanent data loss.
From the tool's definition Tool name 'json_del' and description 'Delete a JSON value from Redis at a given path' explicitly indicates irreversible deletion of data stored in Redis.

Documented attack patterns abuse exactly the kind of access json_del gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Redis MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for json_del:
{
"version": "1",
"default": "deny",
"hide": [
"json_del"
]
}json_del disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a JSON value from Redis at a given path. Args: name: The Redis key where the JSON document is stored. path: The JSON path to delete (default: root '$'). Returns: A success message or an error message. It is categorised as a Destructive tool in the Redis MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Redis MCP Server MCP server in PolicyLayer and add a rule for json_del: 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 Redis MCP Server. Nothing to install.
json_del is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the json_del 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 json_del. 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.
json_del is provided by the Redis MCP Server MCP server (redis/mcp-redis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
