AI agents call get_version to retrieve information from PTT MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward informational read operation that queries the server's version metadata. It has no side effects, does not modify data, does not execute code, and poses minimal risk if misused by an AI agent.
From the tool's definition Tool name 'get_version' and description 'Returns the current version of the PTT MCP Server' indicate a simple query operation that retrieves version information without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access get_version gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PTT MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_version:
{
"version": "1",
"default": "deny",
"tools": {
"get_version": {}
}
}get_version is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns the current version of the PTT MCP Server. It is categorised as a Read tool in the PTT MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PTT MCP Server MCP server in PolicyLayer and add a rule for get_version: 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 PTT MCP Server. Nothing to install.
get_version 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 get_version 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 get_version. 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.
get_version is provided by the PTT MCP Server MCP server (pyptt/ptt_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
