What kicad_run_spice does on Altium-MCP-Suite
AI agents invoke kicad_run_spice to trigger actions in Altium-MCP-Suite. 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 kicad_run_spice is rated High
Runs SPICE simulations; arbitrary circuit parameters could cause resource exhaustion or unintended computations.
From the tool's definition uninformative description; kicad_run_spice suggests circuit simulation execution
Attacks that exploit this kind of access
The rule that runs kicad_run_spice 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 kicad_run_spice, this is the rule to start with:
kicad_run_spice 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 Altium-MCP-Suite, apply this rule, and every kicad_run_spice call is checked against it from then on.
Questions about kicad_run_spice
kicad_run_spice is a execute tool on the Altium-MCP-Suite MCP server. It is categorised as a Execute tool in the Altium-MCP-Suite MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Altium-MCP-Suite MCP server in PolicyLayer and add a rule for kicad_run_spice: 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 Altium-MCP-Suite. Nothing to install.
kicad_run_spice 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 kicad_run_spice 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 kicad_run_spice. 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.
kicad_run_spice 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.
