## Summary

The MCP Support Policy configures Flex Gateway to support MCP server instances. You must apply this
policy to all MCP server instances for the instance to function properly. If you don’t apply this
policy, Flex Gateway might throw a runtime error.

The MCP Support policy enables the **Total MCP Calls** metric that tracks the total successful and
unsuccessful calls made to the MCP server. To view the total MCP calls, see
[Viewing Key Metrics in API Manager for Managed Flex Gateway](https://docs.mulesoft.com/gateway/1.12/flex-managed-view-api-metrics).

There are no configuration parameters for this policy.

> [!NOTE] This policy must come first in policy order. If this policy doesn’t come first, Flex
> Gateway might throw a runtime error.

### Flex Gateway Local Mode

The MCP Support policy isn’t supported in Local Mode.
