# Usage, Billing, Exports, and Access Control

> Understand usage attribution, rate limiting, quotas, and request-level access controls for Sports MCP Server.

# Usage, Billing, Exports, and Access Control

Sports MCP Server emits structured usage data and enforces access control at request time.

## What the server tracks

* request-level usage
* tool-level usage
* error paths
* source-family usage
* resolution and crosswalk behavior

## Access control layers

* product-scoped API keys
* rate limits
* quotas
* optional trusted-forwarder lineage

## Why this matters in hybrid flows

<Tabs>
  <Tab title="Single-source tools">
    Usage attribution is straightforward because one tool maps cleanly to one source family.
  </Tab>

  <Tab title="Hybrid tools">
    Hybrid tools can use more than one source family, so provenance and usage need to stay explicit instead of being hidden behind one synthetic sports answer.
