AI agents call get-rankings to retrieve information from Cfbd without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool fetches team ranking information from the College Football Data API. The operation is a simple data retrieval with no parameters that would allow modification, deletion, or execution of code. It has no financial impact and cannot be weaponized to cause harm. The blast radius of misuse is minimal—an agent could only retrieve ranking data it's authorized to access.
From the tool's definition Tool name 'get-rankings' and description 'Check team rankings' indicate a read-only query operation that retrieves ranking data without modification or side effects.
Documented attack patterns abuse exactly the kind of access get-rankings gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Cfbd, and nothing reaches the server without passing your rules. This is the rule we recommend for get-rankings:
{
"version": "1",
"default": "deny",
"tools": {
"get-rankings": {}
}
}get-rankings 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.
Check team rankings. It is categorised as a Read tool in the Cfbd MCP Server, which means it retrieves data without modifying state.
Register the Cfbd MCP server in PolicyLayer and add a rule for get-rankings: 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 Cfbd. Nothing to install.
get-rankings 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-rankings 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-rankings. 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-rankings is provided by the Cfbd MCP server (lenwood/cfbd-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Cfbd, 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.
