AI agents call get_event_matches_simple to retrieve information from Tba without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and presents match information from an event without modifying data, executing commands, or performing destructive operations. The 'simple' variant explicitly reduces data payload for efficiency. No capability to create, delete, or execute arbitrary operations is indicated.
From the tool's definition Tool description states it 'List matches at an event' with 'reduced match fields', indicating data retrieval with no modification or side effects.
Attacks that exploit this kind of access
List matches at an event with reduced match fields (no game-specific score breakdown or videos). Lighter than get_event_matches. It is categorised as a Read tool in the Tba MCP Server, which means it retrieves data without modifying state.
Register the Tba MCP server in PolicyLayer and add a rule for get_event_matches_simple: 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 Tba. Nothing to install.
get_event_matches_simple 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_event_matches_simple 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_event_matches_simple. 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_event_matches_simple is provided by the Tba MCP server (@withinfocus/tba-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
