What proj_lock_designator does on Altium-MCP-Suite
AI agents use proj_lock_designator to create or update resources in Altium-MCP-Suite, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Altium-MCP-Suite environment.
Why proj_lock_designator is rated Medium
The tool name indicates a state modification (locking) of designators (component identifiers) in a project context. This is a reversible Write operation—designators can be unlocked later. While the empty description limits certainty, the naming convention and server context (persistent DelphiScript bridge for design automation) suggest it modifies project data rather than executing arbitrary code or deleting data.
From the tool's definition Tool name 'proj_lock_designator' suggests modifying designator lock state in Altium Designer projects. Given the server's scope (290+ design automation tools), this likely creates or modifies designator locking metadata reversibly.
Attacks that exploit this kind of access
The rule that runs proj_lock_designator safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Altium-MCP-Suite, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For proj_lock_designator, this is the rule to start with:
proj_lock_designator 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 Altium-MCP-Suite, apply this rule, and every proj_lock_designator call is checked against it from then on.

proj_lock_designator is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the proj_lock_designator 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 proj_lock_designator. 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.
proj_lock_designator is provided by the Altium-MCP-Suite MCP server (M-R-Abedini/Altium-MCP-Suite). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
