PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Guide, and nothing reaches the server without passing your rules. This is the rule we recommend for greet:
{
"version": "1",
"default": "deny",
"tools": {
"greet": {}
}
}greet is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Yes. Add a rate_limit block to the greet 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 greet. 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.
greet is provided by the MCP Guide MCP server (switchblxdee/mcp_guide). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Guide, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
