AI agents call get_sheet_info to retrieve information from Kicad without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix is a standard naming convention for read-only data retrieval. In the context of KiCad automation, retrieving sheet information (schematic metadata, properties, hierarchy) has no side effects and does not modify design data. Though the description is empty, the tool name provides sufficient evidence for classification.
From the tool's definition Tool name 'get_sheet_info' indicates retrieval of sheet information. The naming convention aligns with a read-only accessor (get_*), and sibling tools include write/execute operations (add_*), distinguishing this as a query operation.
Attacks that exploit this kind of access
get_sheet_info. It is categorised as a Read tool in the Kicad MCP Server, which means it retrieves data without modifying state.
Register the Kicad MCP server in PolicyLayer and add a rule for get_sheet_info: 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 Kicad. Nothing to install.
get_sheet_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_sheet_info 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 get_sheet_info. 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.
get_sheet_info is provided by the Kicad MCP server (productofamerica/mcp-server-kicad). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
