Each example is a small, self-contained project you can clone and run. Most have a one-click deploy button.

​
Webhooks

Handle every message in your own code. Pair these with webhook routing.

Cloudflare Worker receiver

A single-file Worker that verifies signatures with Web Crypto and replies to each routed message with messages.send.@wassist/sdk · Cloudflare Workers · one-click deploy

Vercel eve agent

A minimal eve agent with the @wassist/eve channel. It handles signatures, typing indicators and replies for you.@wassist/eve · Vercel · one-click deploy
Deploy to Cloudflare Workers Deploy with Vercel After deploying, create a webhook pointing at the deployed URL under Settings → Developers → Webhooks (for eve, add /eve/v1/wassist). Then route a number to it, or your own sandbox chat.

​
Apps (alpha)

MCP servers packaged as Wassist Apps. Your agents call their tools, and each tool call arrives with signed Wassist context.

App MCP server

The smallest Wassist-aware app: an Express server with two loyalty tools (get_points, redeem). It verifies the context token, works out whether the call came from WhatsApp or a dashboard test, and has a signed setup page.@wassist/sdk/apps · Express · auth: none

Google Calendar Booking

A complete, production-style app on Cloudflare Workers. Customers check availability, then book, reschedule and cancel appointments in a business’s Google Calendar. It includes a setup page with Google OAuth, and per-customer ownership of bookings.@wassist/sdk/apps · Cloudflare Workers + KV · setup page
To try one, run it behind an HTTPS tunnel, create an app under Settings → Developers → Apps, paste the manifest (or set the MCP URL and Who logs in: Nobody), then Sync tools → Publish → Install:
Then ask your agent something that needs the tool, for example “How many points do I have?”. Try it both in Test Chat on the agent’s page and on the sandbox number.
