AI agents call getServer to retrieve information from Executor without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries configuration details about registered MCP integrations without making any changes. It is a read-only inspection operation with no side effects or ability to modify state.
From the tool's definition Tool name is 'getServer' and description states 'Inspect a registered MCP integration' — indicates data retrieval only. No modifications, deletions, or side effects are mentioned.
Documented attack patterns abuse exactly the kind of access getServer gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Executor, and nothing reaches the server without passing your rules. This is the rule we recommend for getServer:
{
"version": "1",
"default": "deny",
"tools": {
"getServer": {}
}
}getServer is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Executor MCP server in PolicyLayer and add a rule for getServer: 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 Executor. Nothing to install.
getServer 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 getServer 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 getServer. 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.
getServer is provided by the Executor MCP server (rhyssullivan/executor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
