Generate Lightning Web Components (LWC) or Aura components with customizable templates and output directories
AI agents use generate_component to create or update resources in Salesforce MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Salesforce MCP Server environment.
This tool creates new code artifacts (LWC/Aura components) and writes them to specified directories, which constitutes reversible modification of the Salesforce org. While not destructive (components can be deleted), the high severity reflects the potential blast radius: generated components could introduce security vulnerabilities, break existing functionality, or deploy malicious code if an AI agent misuses the…
From the tool's definition Tool description states it will 'Generate Lightning Web Components (LWC) or Aura components' with 'customizable templates and output directories'.
Documented attack patterns abuse exactly the kind of access generate_component gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Salesforce MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_component:
{
"version": "1",
"default": "deny",
"tools": {
"generate_component": {
"limits": [
{
"counter": "generate_component_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} generate_component 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.

Generate Lightning Web Components (LWC) or Aura components with customizable templates and output directories. It is categorised as a Write tool in the Salesforce MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Salesforce MCP Server MCP server in PolicyLayer and add a rule for generate_component: 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 Salesforce MCP Server. Nothing to install.
generate_component 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 generate_component 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 generate_component. 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.
generate_component is provided by the Salesforce MCP Server MCP server (advancedcommunities/salesforce-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Salesforce MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
