WHAT IT DOES

What upload_rom does on Mcp Control Plane

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

RISK

Why upload_rom is rated Medium

The tool uploads files to a remote system, which is a Write operation (creates new data). Severity is medium because: (1) it's reversible (uploaded files can be deleted), (2) blast radius is limited to the emulation ROM directory, and (3) the primary risk is storage consumption or accidental ROM uploads rather than system compromise. It does not execute code, delete irreversibly, or move money.

From the tool's definition Tool description states 'Upload a local, user-provided game dump into Emulation/roms/<system> via SFTP' — this creates/adds files to a remote filesystem.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs upload_rom safely

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

upload_rom Rate-limited

upload_rom 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 Mcp Control Plane, apply this rule, and every upload_rom call is checked against it from then on.
