WHAT IT DOES

What switch_workspace does on Starfield

AI agents use switch_workspace to create or update resources in Starfield, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Starfield environment.

Parameter	Type	Required	Description
`workspaceId`	string	Yes	Target workspace ID from list_workspaces

Parameters from the server's own tool schema.

RISK

Why switch_workspace is rated Medium

An AI agent can call switch_workspace faster than any human can review: one bad instruction and it creates or modifies resources in Starfield by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs switch_workspace safely

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

switch_workspace Rate-limited

switch_workspace 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Starfield, apply this rule, and every switch_workspace call is checked against it from then on.
