Phone Workflow Automation With Webhooks, API & MCP

What is it?

Phone workflow automation connects a call outcome to the systems that act on it. LiveMSG is designed to record and transcribe a caller response, then make the result available by email and, once contracts are final, through signed webhooks, an API and permissioned MCP-compatible tools. The workflow may route or classify the message, while a human verifies high-impact details.

From voice to an event

A caller speaks naturally after the recorded prompt. Processing produces a transcript and links it to the call record. A message-ready event can then notify the receiving workflow, which decides whether to create a lead, ticket or task.

Why webhooks and APIs work together

The webhook should carry a unique event ID, timestamp, event type and signature. The receiver can then use the API to retrieve the current record. This pattern keeps notifications small and makes reconciliation possible after a temporary failure.

Where MCP fits

MCP can make a small set of authorised actions available to compatible AI clients, such as listing new messages or retrieving one transcript. The final tool catalogue, permission boundaries and audit model must be specified during the platform build.

Keep humans in consequential decisions

Automation can suggest categories and urgency, but it may misread speech or infer more than the caller said. Workflows should preserve the original transcript and audio, flag uncertainty and require human review before quotes, safety actions or other high-impact outcomes.

Frequently asked questions

What is a webhook?+

It is an HTTPS message one system sends another when an event occurs.

What is the difference between a webhook and an API?+

A webhook pushes an event notification; an API lets software request the current record when needed.

What is MCP?+

The Model Context Protocol is a way for compatible AI clients to discover and call authorised tools and resources.

Is the LiveMSG technical contract final?+

No. Event names, payloads, limits, authentication and MCP tools remain implementation inputs.
