AI agents call get_symbol_pins 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.
This tool queries and retrieves pin information from library symbols without creating, modifying, deleting, or executing any operations. It is a straightforward read operation on symbol metadata.
From the tool's definition Tool name 'get_symbol_pins' and description 'Get pin info for a symbol' indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access

Register the Kicad MCP server in PolicyLayer and add a rule for get_symbol_pins: 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_symbol_pins 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_symbol_pins 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_symbol_pins. 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_symbol_pins 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.
