list_callbacks

Who this business promised to ring back, and when. Open promises first, plus anything cancelled or completed in the last seven days - a promise that was NOT kept has to stay visible rather than simply disappear. `askedBy` matters and should not be flattened: 'customer' means they asked us to ring, 'us' means we offered, and those are different obligations when a backlog has to be triaged. `theySaid` is the customer's own words - quote it, never paraphrase.

This is the exact text the model reads before deciding to call.

curl -X POST https://us.avrosh.com/mcp \
  -H "Authorization: Bearer $AVROSH_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"list_callbacks","arguments":{"business_id":"926135ac-487d-4367-8bad-25397d0d4b87"}}}'

The result arrives as an MCP content block; the JSON below is what the text field parses to.

{
  "callbacks": [
    {
      "id": "cb_1…",
      "e164": "+6281234",
      "name": "Andi",
      "askedBy": "customer",
      "status": "pending",
      "dueAt": "2026-08-20T02:00:00.000Z",
      "theySaid": "ring me after lunch"
    }
  ]
}

Paste the URL into your assistant and log in. Avrosh implements OAuth 2.1, so an MCP client discovers the authorisation server, registers itself, and opens a browser asking you to sign in here. That is the whole setup: nothing to copy, no key to keep, and nothing to rotate later.

https://us.avrosh.com/mcp

For something with no browser to log in with — a cron job, a script, an automation platform — there is a second door: a bearer key made in the dashboard under Docs, shown once because only its hash is stored, and revocable at any time.

curl https://us.avrosh.com/mcp \
  -H "Authorization: Bearer $AVROSH_KEY"

Either way the boundary is the same one: an assistant reaches every business on the account it signed in to, and no others. There are no scopes to configure and nothing to switch on — what bounds it is whose account it is, enforced in the database rather than by a permission anybody sets.
