# Autumn

> Connect Autumn to Mistle

## Overview

Connect to Autumn through Autumn's hosted MCP server with an Autumn secret key.

The Autumn integration exposes billing, customer, plan, balance, and request-log workflows to agent runtimes through Autumn's official hosted MCP endpoint.

## Connect In Mistle

Open **Integrations** in the dashboard, choose **Autumn**, then select **Secret key**.

Enter:

| Field             | Value                                                                            |
| ----------------- | -------------------------------------------------------------------------------- |
| Autumn secret key | Autumn secret key with access to the organization billing data agents should use |

Mistle stores the secret key on the connection and injects it into requests to Autumn MCP through managed egress.

## Use With A Sandbox Profile

After the connection exists:

1. Open the sandbox profile that should use Autumn.
2. Add Autumn to the profile's integration configuration.
3. Select the Autumn MCP server.
4. Save and publish the profile version.
