MightyCall hooks your professional phone system right into any AI client you're running. You don't gotta switch between tabs or write a bunch of API code; your agent handles all the comms stuff—call routing, managing records, checking voicemails—all from within the chat window. When you need to keep track of what’s going on with calls, you use `list_calls` to pull detailed activity history. You'll see a full record of your most recent inbound and outbound calls, getting metadata like the status code and who was involved in each interaction. If you just want to check out who exists without knowing their call history, run `list_contacts` to get the complete list of every existing client record. For immediate follow-up, you use `make_call`. Your agent initiates a live outgoing phone call directly from one of your registered business numbers straight to the recipient. It's instant and requires zero manual setup. You can also check out what businesses are even connected by calling `list_business_numbers`, which pulls a complete rundown of every active number on your account. Dealing with customer data is easy too. If you need to build a new client file, use the `create_contact` tool; it lets your agent add a brand-new contact record using just basic profile details. You'll keep everything organized right in your system. Don't forget about messages left behind. Your team can track down specific customer inquiries by running `list_voicemails`. This pulls a summary and the full details of your most recent voicemails, making sure your agent knows exactly which message needs attention first—especially if some are marked as unread. Basically, you've got the power to monitor all call activity history with `list_calls`, track every voicemail in the queue using `list_voicemails`, kick off outgoing calls instantly via `make_call`, manage your whole client database by creating new contacts with `create_contact` or pulling existing ones with `list_contacts`, and always know what numbers you're playing with by listing them all out with `list_business_numbers`. ## Tools ### create_contact Adds a new contact record into your system using basic profile information. ### list_business_numbers Retrieves a list of all active business phone numbers registered to the account. ### list_calls Gets a detailed record of your most recent inbound and outbound call activities. ### list_contacts Fetches a full list of all existing contacts in the system. ### list_voicemails Pulls a summary and details of your most recent voicemails, marking which ones are unread. ### make_call Initiates an outgoing phone call from one of your registered business numbers to a specified recipient. ## Prompt Examples **Prompt:** ``` List all recent calls in my MightyCall account. ``` **Response:** ``` I've retrieved your recent calls.

Instead of waiting for the customer's call back, they ask their agent to run `list_voicemails`. The agent pulls two unread messages—one from 'Global Tech' and one unknown number—allowing the rep to immediately triage which client needs attention first. ### Field Sales Follow-up An SDR finishes a meeting. They ask their agent to run `create_contact` with the new attendee details, then use `make_call` right away to schedule the next step. The system handles both data entry and communication in one sequence. ### Daily Call Audit A manager needs a report on last week’s calls. They ask their agent to run `list_calls`. The agent returns structured data listing the call status, total duration, and key participants for auditing purposes. ### Building Contact Lists A developer needs to know which numbers are available for a new campaign. They ask their agent to run `list_business_numbers`, getting a clean list of all active lines before writing the deployment script. ## Benefits - See every call's metadata instantly.
