Fetch MLB game results for a given date (default is today)
AI agents call get_daily_results to retrieve information from Baseball without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves historical game result data from the MLB Stats API. It has no side effects, cannot modify data, and presents no security risk beyond potentially exposing publicly available sports statistics. The low severity reflects the minimal blast radius if an AI agent calls this tool repeatedly or with unexpected arguments.
From the tool's definition Tool fetches/retrieves MLB game results with no modification capability. Description uses "Fetch" which is a read operation. No parameters suggest data creation, modification, or deletion.
Documented attack patterns abuse exactly the kind of access get_daily_results gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Baseball, and nothing reaches the server without passing your rules. This is the rule we recommend for get_daily_results:
{
"version": "1",
"default": "deny",
"tools": {
"get_daily_results": {}
}
}get_daily_results 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 get_daily_results 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_daily_results. 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_daily_results is provided by the Baseball MCP server (mpizza/mcp_mlb_statsapi). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Baseball, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
