Install

How do I install the io.usefulapi/smoobu MCP server?

io.usefulapi/smoobu is a hosted endpoint at https://smoobu.usefulapi.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 20 exposed · ~2,672 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
smoobu_check_availability ~172

Check which properties can be booked for an arrival/departure pair and get the total price for each; unavailable ones come back with the reason (minimum stay, too many guests, arrival day, lead time...). Read-only, books nothing. Smoobu: POST /booking/checkApartmentAvailability.

Common questions

What is the io.usefulapi/smoobu MCP server?

io.usefulapi/smoobu is an MCP server listed in the public MCP registry as io.usefulapi/smoobu. Check vacation-rental reservations, rates, availability and guest messages, and update bookings. This page covers its hosted endpoint (https://smoobu.usefulapi.io/mcp).

Is the io.usefulapi/smoobu MCP server safe to use?

io.usefulapi/smoobu scores 74 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.usefulapi/smoobu MCP server expose?

io.usefulapi/smoobu exposes 20 tools: smoobu_get_user, smoobu_list_apartments, smoobu_get_apartment, smoobu_list_reservations, smoobu_get_reservation, and 15 more. Their descriptions and schemas cost roughly 2,672 tokens of context every time the server is loaded.

Does the io.usefulapi/smoobu MCP server require authentication?

Yes. io.usefulapi/smoobu asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the io.usefulapi/smoobu MCP server still maintained?

io.usefulapi/smoobu is still listed as active in the MCP registry. We last reached this channel on 4 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
