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
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified
Tool Safety0

Capabilities0

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.
Checks we ran (4)
- TLS certificate

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.

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.
remote · jackrabbit-class.usefulapi.io
claude mcp add --transport http io-usefulapi-jackrabbit-class 'https://jackrabbit-class.usefulapi.io/mcp'
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.
