The server completed its last measured handshake. This is an observation, not a guarantee.

Unmeasured means there is not enough evidence to decide. How these checks work
Start using Appointment Booking
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.
Claude Code
claude mcp add --transport http appointment-booking https://hatchloop.dev/mcp/appointment-bookingCapabilities
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]
DiscoveredFind real businesses near a place, sorted by distance (nearest of those examined; see result.search). Data: OpenStreetMap (ODbL, (c) OSM contributors); phone, website, hours only when mapped. Coverage varies; community-mapped, NOT verified by us; source=openstreetmap rows cannot be booked. Answers within about 5 s: status partial (search_in_progress) means repeat the call. If OSM is down: retriable 'temporarily unavailable', never invented rows. [free, no key] [beta]
DiscoveredRetrieve the final OutcomeReceipt for a completed operation. [free, no key]
DiscoveredQuery the current state of any in-flight async operation by operation_id. [free, no key]
DiscoveredTurn a public booking URL into a callable smb_id for send_message and capture_lead. But schedule_appointment only completes on Cal.com bound to our one connected account — the other 11 always fail schedule_appointment honestly, uncharged. Detects 12 platforms (Cal.com, Calendly, Doctolib, Booksy, Fresha, OpenTable, Setmore, Square, Acuity, Schedulista, Squarespace, BookMyCity). Idempotent — calling twice returns the same smb_id. [free, requires key] [limited]
DiscoveredReturn 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]
DiscoveredCheck availability, book, or cancel via Cal.com. Only completes when the SMB's imported booking link is bound to this deployment's ONE connected Cal.com account; otherwise fails honestly (booking_destination_unmapped) with no charge. No working booking path exists yet for non-Cal.com platforms (voice AI, web form) — those SMBs fail honestly instead of a fabricated confirmation. [from $0.15/call, variable, not charged while no payment rail is on] [async→get_outcome] [limited]
DiscoveredService 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]
DiscoveredLook up what we know about a business in our supply network: contact channels, capabilities, last verification. A DIRECTORY LOOKUP - it does not contact the business. Supply-network ids only, not osm:... ids. [free, no key] [limited]
