WHAT IT DOES

What proj_run_erc does on Altium-MCP-Suite

AI agents invoke proj_run_erc 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.

RISK

Why proj_run_erc is rated High

ERC (Electrical Rules Check) is an automated validation/audit operation that executes against the current design. While it is non-destructive and read-intent (checking for violations), it is classified as Execute because it triggers a computational process on the design data whose behavior depends on arguments (the focused project and its rules).

From the tool's definition Tool name 'proj_run_erc' and description 'Run Electrical Rules Check on the focused project' indicate execution of a rules-checking process.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs proj_run_erc 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_run_erc, this is the rule to start with:

proj_run_erc Rate-limited

proj_run_erc 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.

          "max": 10,

    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Altium-MCP-Suite, apply this rule, and every proj_run_erc call is checked against it from then on.

FAQ

Questions about proj_run_erc

What does the proj_run_erc tool do? +

Run Electrical Rules Check on the focused project. 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.

How do I enforce a policy on proj_run_erc? +

Register the Altium-MCP-Suite MCP server in PolicyLayer and add a rule for proj_run_erc: 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.

What risk level is proj_run_erc? +

proj_run_erc is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit proj_run_erc? +

Yes. Add a rate_limit block to the proj_run_erc 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.

How do I block proj_run_erc completely? +

Set action: deny in the PolicyLayer policy for proj_run_erc. 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.

What MCP server provides proj_run_erc? +

proj_run_erc 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.
