WHAT IT DOES

What mcp_restore does on Claude C2

AI agents use mcp_restore to create or update resources in Claude C2, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude C2 environment.

RISK

Why mcp_restore is rated Medium

This tool restores an MCP server from backup, which is a reversible write operation that modifies system state and configuration. While restoration itself is typically undoable (you could restore again from a different backup), the operation overwrites current system state.

From the tool's definition Tool name 'mcp_restore' and description 'Restore MCP server from backup' indicates restoration of data/configuration from a backup source, which modifies system state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs mcp_restore safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude C2, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mcp_restore, this is the rule to start with:

mcp_restore Rate-limited

mcp_restore 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.
