Add a custom connector in Claude pointing at this URL:
+
+ {{ mcp_url }}
+
+
+
Name the connector without a dot. Use something like
intervals — notintervals.icu.
Claude Desktop and mobile currently don’t support a . in the
connector name, and it will stop the tools from loading.
+
+
Step by step:
+
+
In Claude, open Settings → Connectors
+ (on claude.ai this may be Customize → Connectors).
+
Click Add custom connector.
+
Name it intervals — letters only, no dot.
+
URL: paste the address above (use Copy).
+
Click Add, then sign in with Google when prompted.
