WHAT IT DOES

What switch_connection does on BullMQ MCP Server

AI agents call switch_connection as a supporting operation in BullMQ MCP Server workflows.

RISK

Why switch_connection is rated Low

This tool changes the active Redis connection context within the MCP session. It doesn't read, write, execute, delete data, or move money — it only changes which connection is currently active. The closest category is 'Other' since it's a session/context management operation. Minor misuse risk: switching to a wrong connection could misdirect subsequent operations, but the tool itself causes no direct harm.

RECOMMENDED RULE

The rule that runs switch_connection safely

PolicyLayer is an MCP gateway: it sits between your AI agents and BullMQ MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For switch_connection, this is the rule to start with:

switch_connection Rate-limited

switch_connection gets a rate cap, and everything else on the server is denied unless you say otherwise.
