A simple greeting tool with customizable greeting
AI agents call greet to retrieve information from Codemesh without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or returns a greeting string based on customizable parameters. It performs no state changes, does not execute external code, does not delete or modify persistent data, and does not involve financial transactions. It is a pure read operation that outputs a formatted message to the user.
From the tool's definition Tool name 'greet' and description 'A simple greeting tool with customizable greeting' indicate a function that returns a greeting message without side effects, data modifications, or external operations.
Documented attack patterns abuse exactly the kind of access greet gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Codemesh, 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.

A simple greeting tool with customizable greeting. It is categorised as a Read tool in the Codemesh MCP Server, which means it retrieves data without modifying state.
Register the Codemesh MCP server in PolicyLayer and add a rule for greet: 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 Codemesh. Nothing to install.
greet 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 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 Codemesh MCP server (kiliman/codemesh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Codemesh, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
