What this MCP does

Verifies US phone numbers for line type, carrier, activity and likely disconnection status, and known TCPA litigator status.

get_credit_balance
Check the remaining pre-paid API credit balance for the connected NumberBroom account. Free to call — does not spend credits.

{'type': 'object', '$schema': 'https://json-schema.org/draft/2020-12/schema', 'properties': {}}
verify_phone_number
Verify a single US phone number: carrier-level line type (mobile, landline, VoIP, toll-free or other), carrier name, an activity score with a likely-disconnected flag (a dead mobile still reports as mobile, so read isLikelyDisconnected, not lineType), and whether the number is a known TCPA litigator. Does not check Do Not Call registries. Costs $0.20, charged against the caller's NumberBroom API credit balance — a number that fails to parse as a phone number is not charged. Get an API key at https://numberbroom.com/settings.
