MCP tools · 16 exposed · ~1,894 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 →

Install

How do I install the TimeTac MCP by usefulapi server?

TimeTac MCP by usefulapi is a hosted endpoint at https://timetac.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 TimeTac MCP by usefulapi server?

TimeTac MCP by usefulapi is listed in the public MCP registry as io.usefulapi/timetac. Read hours, absences and projects; start timers, add entries, approve leave in TimeTac. This page covers its hosted endpoint (https://timetac.usefulapi.io/mcp).

Is the TimeTac MCP by usefulapi server safe to use?

TimeTac 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 TimeTac MCP by usefulapi server expose?

TimeTac MCP by usefulapi exposes 16 tools: timetac_list_users, timetac_get_user, timetac_list_time_trackings, timetac_current_time_trackings, timetac_list_absences, and 11 more. Their descriptions and schemas cost roughly 1,894 tokens of context every time the server is loaded.

Does the TimeTac MCP by usefulapi server require authentication?

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

TimeTac 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 TimeTac MCP by usefulapi server?

VerifyMCP ran 4 checks on TimeTac 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 TimeTac 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.
