How do you connect Claude to something like Strava or a custom data source?

You bridge external APIs through MCPs. Common services often already have community connectors—search GitHub or an MCP directory for "Strava MCP" before you build.

If nothing fits:

• Wrap the vendor API in a tiny MCP (you can vibe-code a thin layer if you read API docs patiently).
• Expect more debugging than off-the-shelf installs.

Foundations first—stable MCP installs—then chase bespoke connectors.
