What pcb_snap_to_grid does on Eda Agent
AI agents use pcb_snap_to_grid to create or update resources in Eda Agent, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Eda Agent environment.
Why pcb_snap_to_grid is rated Medium
Based on the tool naming convention and context within an Altium Designer automation server, 'pcb_snap_to_grid' performs a reversible layout modification operation—adjusting element positioning to grid alignment. This is a Write operation (modifies design state) rather than Read (inspection only), Execute (running arbitrary code), or Destructive (irreversible deletion).
From the tool's definition Tool name 'pcb_snap_to_grid' and its sibling tools (pcb_*) operate on PCB design documents; snapping to grid modifies PCB layout state reversibly. The description is empty, limiting direct evidence.
Attacks that exploit this kind of access
The rule that runs pcb_snap_to_grid safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Eda Agent, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pcb_snap_to_grid, this is the rule to start with:
pcb_snap_to_grid 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 Eda Agent, apply this rule, and every pcb_snap_to_grid call is checked against it from then on.
Questions about pcb_snap_to_grid
pcb_snap_to_grid is a write tool on the Eda Agent MCP server. It is categorised as a Write tool in the Eda Agent MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Eda Agent MCP server in PolicyLayer and add a rule for pcb_snap_to_grid: 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 Eda Agent. Nothing to install.
pcb_snap_to_grid 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 pcb_snap_to_grid 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 pcb_snap_to_grid. 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.
pcb_snap_to_grid is provided by the Eda Agent MCP server (salitronic/eda-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
