What apply_unified_patch_remote does on Mcp Control Plane
AI agents invoke apply_unified_patch_remote to trigger actions in Mcp Control Plane. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why apply_unified_patch_remote is rated High
Applying a unified diff modifies files on a remote server. This is an Execute-level action because it triggers an external operation (remote file modification) whose effects depend on the patch content. It could overwrite or alter arbitrary files depending on the diff provided, making it high severity.
From the tool's definition 'Apply a unified diff on the remote server without shell quoting issues' — executes a patch operation on a remote server, modifying files in place
Attacks that exploit this kind of access
The rule that runs apply_unified_patch_remote 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 apply_unified_patch_remote, this is the rule to start with:
apply_unified_patch_remote stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 apply_unified_patch_remote call is checked against it from then on.
Questions about apply_unified_patch_remote
Apply a unified diff on the remote server without shell quoting issues. It is categorised as a Execute tool in the Mcp Control Plane MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for apply_unified_patch_remote: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Control Plane. Nothing to install.
apply_unified_patch_remote is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the apply_unified_patch_remote rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for apply_unified_patch_remote. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
apply_unified_patch_remote is provided by the Mcp Control Plane MCP server (albertik322-sudo/mcp-control-plane). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
