Appointment Booking MCP server

• check_booking_linkFree

  Free, instant pre-flight check for a booking URL. Classifies which booking platform a URL belongs to and tells you whether import_booking_url will accept it, WITHOUT fetching the page or spending money. Returns the platform, the exact smb_id import_booking_url would assign, the channels the booking will route through, and the inferred country. Use it to de-risk a paid booking BEFORE calling import_booking_url + schedule_appointment. [free, no key]

• find_businessFree

  Given criteria (vertical, location, capability, price band, availability window), return ranked candidate businesses from our supply network. THE NETWORK IS SMALL AND STILL MOSTLY SAMPLE DATA: entries that are not real are named [DEMO] and flagged is_demo - check that field before acting on a result. [free, no key]

• get_outcomeFree

  Retrieve the final OutcomeReceipt for a completed operation. [free, no key]

• get_statusFree

  Query the current state of any in-flight async operation by operation_id. [free, no key]

• import_booking_urlFree

  Turn ANY public booking URL (Cal.com, Calendly, Doctolib, Booksy, Fresha, OpenTable, Setmore, Square, Acuity, Schedulista, Squarespace, BookMyCity) into a callable smb_id you can immediately use with schedule_appointment, send_message, or capture_lead. Idempotent — calling twice returns the same smb_id. [free, requires key]

• preview_costFree

  Return an expected cost estimate, latency estimate, and success-probability estimate for a proposed call before execution. Returns the exact price when it is fixed, and a min/max range when the cost depends on channel or outcome. It does not promise an accuracy percentage - check cost_range. [free, no key]

• schedule_appointmentFree

  Availability lookup, hold, confirm, reschedule, or cancel appointments with an SMB. Routes through the SMB's native booking system if available, falls back to voice AI or web form. [from $0.15/call, variable] [async→get_outcome]

• self_testFree

  Service health probe: runs 6 internal checks and reports how many passed. Confirms the server is up and responding - it does NOT probe each tool individually. Use to verify connectivity before production use. [free, no key]

• verify_businessFree

  Look up what we know about a business in our supply network: its contact channels, capabilities, and when the record was last verified. This is a DIRECTORY LOOKUP - it does not contact the business. [free, no key]
