redis_lpush · Multi-Database MCP Server MCP: Risk & Policy

WHAT IT DOES

What redis_lpush does on Multi-Database MCP Server

AI agents use redis_lpush to create or update resources in Multi-Database MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Multi-Database MCP Server environment.

WHY IT NEEDS A POLICY

Why redis_lpush needs a policy

redis_lpush prepends values to a Redis list, which is a write/create operation that modifies data. It is reversible (items can be removed), so it does not qualify as Destructive. The severity is medium because it modifies data structures and requires FULL mode access, but does not delete or irreversibly alter data.

From the tool's definition Prepend one or more values to a list (requires FULL mode)

Verdict

redis_lpush Rate-limited

redis_lpush stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
