Comprehensive Model Context Protocol server for managing Home Assistant through AI assistants.
Nothing to run from here
Appointment Booking is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http appointment-booking-mcp https://hatchloop.dev/mcp/appointment-bookingReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
9 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Find 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: retriabl

Look 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]

Check 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, v

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]

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]
No parameter schema on file.
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

Turn 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.

Release 0.2.13 · scanned 24 Oct 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.

This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 0.2.13.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Appointment Booking can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
