AI agents call search_race to retrieve information from FirstCycling 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 search operation to retrieve cycling race information. It is purely informational—it queries existing data by name without creating, modifying, deleting, or executing any operations. The tool fits the Read category as it retrieves or queries data with no side effects, similar to other sibling tools on this server (get_race_details, get_race_edition_results, etc.).
From the tool's definition Tool name 'search_race' and description 'Search for races by name' indicate a query operation that retrieves data without modification or side effects.
Documented attack patterns abuse exactly the kind of access search_race gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FirstCycling MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_race:
{
"version": "1",
"default": "deny",
"tools": {
"search_race": {}
}
}search_race 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.
Search for races by name. It is categorised as a Read tool in the FirstCycling MCP Server MCP Server, which means it retrieves data without modifying state.
Register the FirstCycling MCP Server MCP server in PolicyLayer and add a rule for search_race: 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 FirstCycling MCP Server. Nothing to install.
search_race 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 search_race 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 search_race. 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.
search_race is provided by the FirstCycling MCP Server MCP server (r-huijts/firstcycling-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FirstCycling 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.
