UsageWall — landing + waitlist endpoint. Static HTML + Vercel serverless functions.
Usagewall MCP server exists for a simple reason — assistants are far more useful when they can act on Usagewall directly instead of describing what you should do. UsageWall — landing + waitlist endpoint. Static HTML + Vercel serverless functions.
Install in Claude.ai: > Settings → Connectors → Add custom connector → paste https://usagewall.vercel.app/api/mcp
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need 5 environment variables: UNSUBSCRIBE_SECRET, SUPABASE_URL, SUPABASE_SERVICE_ROLE_KEY, RESEND_API_KEY, PUBLIC_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the cloud and infrastructure group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by agenciabakucl-coder; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Usagewall's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
