Copy the following block into your .env file in the project root:

+
+ Your .env content: + 
STRAVA_CLIENT_ID={self.client_id}
+STRAVA_CLIENT_SECRET={self.client_secret}
+STRAVA_REFRESH_TOKEN={refresh_token}

2. Kubernetes Setup (Secret)

+

If you are deploying this server to Kubernetes, run the following command to create the required Secret:

+
+ Kubectl Command: + 
kubectl create secret generic strava-mcp-server-secret \\
+  --from-literal=STRAVA_CLIENT_ID={self.client_id} \\
