  • TLS certificate
  • HSTS header

Checks we could not complete (7)

These are gaps on our side, not findings about this hosted endpoint. We only credit what we can confirm, so a category made up entirely of them scores 0.

  • Authorization in Endpoint SecurityAuthorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  • HTTPS in Endpoint SecurityHTTPS enforcement could not be verified: the plaintext port redirected somewhere other than https, so enforcement is unproven.

Install

How do I install the Jackrabbit Class MCP by usefulapi server?

Jackrabbit Class MCP by usefulapi is a hosted endpoint at https://jackrabbit-class.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.

Common questions

What is the Jackrabbit Class MCP by usefulapi server?

Jackrabbit Class MCP by usefulapi is listed in the public MCP registry as io.usefulapi/jackrabbit-class. Read Jackrabbit Class beta data, create students and add class waitlist entries. This page covers its hosted endpoint (https://jackrabbit-class.usefulapi.io/mcp).

Is the Jackrabbit Class MCP by usefulapi server safe to use?

Jackrabbit Class 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 Jackrabbit Class MCP by usefulapi server expose?

Jackrabbit Class MCP by usefulapi exposes 24 tools: jackrabbit_get_organization, jackrabbit_get_custom_field_labels, jackrabbit_list_options, jackrabbit_list_families, jackrabbit_get_family, and 19 more. Their descriptions and schemas cost roughly 2,929 tokens of context every time the server is loaded.

Does the Jackrabbit Class MCP by usefulapi server require authentication?

Its publisher declares no required credentials for Jackrabbit Class 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 Jackrabbit Class MCP by usefulapi server still maintained?

Jackrabbit Class MCP by usefulapi is still listed as active in the MCP registry. We last reached this channel on 5 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 Jackrabbit Class MCP by usefulapi server?

VerifyMCP ran 4 checks on Jackrabbit Class 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 Jackrabbit Class 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.
