How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not yet verified: we couldn't confirm whether this endpoint requires it. View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port redirected somewhere other than https, so enforcement is unproven. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but the endpoint redirected instead of responding directly. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.Unverified
Stability & Change Management0

Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

How do I install the YouCanBook.me MCP by usefulapi server?
YouCanBook.me MCP by usefulapi is a hosted endpoint at https://youcanbookme.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.
remote · youcanbookme.usefulapi.io
claude mcp add --transport http io-usefulapi-youcanbookme 'https://youcanbookme.usefulapi.io/mcp'
What is the YouCanBook.me MCP by usefulapi server?
YouCanBook.me MCP by usefulapi is listed in the public MCP registry as io.usefulapi/youcanbookme. Manage YouCanBook.me bookings, booking pages, appointment types, team members and locations. This page covers its hosted endpoint (https://youcanbookme.usefulapi.io/mcp).
Is the YouCanBook.me MCP by usefulapi server safe to use?
YouCanBook.me MCP by usefulapi scores 18 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 YouCanBook.me MCP by usefulapi server expose?
YouCanBook.me MCP by usefulapi exposes 18 tools: youcanbookme_list_bookings, youcanbookme_get_booking, youcanbookme_list_profiles, youcanbookme_get_profile, youcanbookme_list_team_members, and 13 more. Their descriptions and schemas cost roughly 2,825 tokens of context every time the server is loaded.
Does the YouCanBook.me MCP by usefulapi server require authentication?
Its publisher declares no required credentials for YouCanBook.me MCP by usefulapi. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.
Is the YouCanBook.me MCP by usefulapi server still maintained?
YouCanBook.me MCP by usefulapi is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What did VerifyMCP test on the YouCanBook.me MCP by usefulapi server?
VerifyMCP ran 4 checks on YouCanBook.me MCP by usefulapi, covering TLS certificate, HSTS header, DNSSEC and Transport. 7 items could not be completed, a gap on our side rather than a finding about YouCanBook.me MCP by usefulapi: Authorization, HTTPS, Schema quality, Stability and 3 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
