AI agents call get_version to retrieve information from Astro MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a straightforward read operation to obtain server version information. It has no capability to modify, execute external operations, or access sensitive ASO data. The blast radius of misuse is negligible—an agent could only retrieve version metadata, which poses minimal security risk.
From the tool's definition Tool name 'get_version' and description 'Get the server version' indicate a simple query operation that retrieves version metadata without side effects or data modifications.
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 Astro 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.
Free to start. No card required.
Get the server version. It is categorised as a Read tool in the Astro MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Astro 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 Astro 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 Astro MCP Server MCP server (timbroddin/astro-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Astro 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.
