For AI assistants

How can an AI assistant make a phone call?

Last updated: November 2026

Two ways. Have the assistant write a request and paste it into Phone Bud, or connect Phone Bud's MCP server so the assistant can call make_call itself. Either way Phone Bud places a real call and returns a transcript and a summary when the call ends.

Make a free call

Option 1: paste a request

Ask your assistant to write who to call, their number, and what to find out. At phone-bud.com/app, put the number in To, paste the rest into Purpose, and press Start call. This works with any assistant.

A good request names the business, its phone number, the one thing to find out, and your own number if you want a callback.

Option 2: connect the MCP server

Create an API key in Phone Bud under Settings, Developer. Then add https://www.phone-bud.com/mcp with the header Authorization: Bearer followed by your key. Clients that accept an API key header, such as Claude Code, work. Connectors that need an OAuth sign-in don't.

What the tools do

  • make_call places a call and returns the transcript and notes when it ends.
  • get_call fetches a call again later.
  • start_campaign calls a list of numbers with the same request.
  • list_contacts and list_agents read your saved contacts and agents.

Things to know

make_call waits up to 10 minutes by default, then hangs up and returns what it has. Raise max_wait_seconds for long holds; calls still end at 30 minutes. A system_prompt replaces the default agent's instructions, so tell it to say it's an AI if asked and never claim to be a person.

Billing

Calls use the same minutes as the web app. The first call is free, up to 5 minutes.
