Sign in at /login with your email: we send a one-time link, no password. Your account page shows your balance, your connection key (starts with ojk_) and your usage. Top up with any of the credit packs; a VAT invoice is emailed by Stripe.
In claude.ai or the Claude apps: Settings → Connectors → Add custom connector. Paste the connector's MCP address (listed on each connector page, for example https://bolt.openjack.dev/mcp) and click Connect. In Claude Code: claude mcp add --transport http <name> <address>.
Claude opens the connector's connect page. Enter your connection key and the platform's own credentials (for Bolt, the API key from the Fleet Portal; for Uber, your developer application's client ID and secret). The connector validates them live and stores them encrypted, tied to the token Claude receives.
Each tool call Claude makes is charged from your balance at the price on the connector page. Failed calls are refunded. When the balance is too low the call returns a message asking you to top up.
Regenerating your connection key invalidates the previous one: existing connections stop working until you reconnect them in Claude with the new key.
Every connector is open source (MIT). You can run it locally with npx or deploy it to your own Cloudflare account; see each repository's README. Self-hosted connectors do not use OpenJack credits.
