Schema Quality & AI Usability69
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 3676 tokens (~175/item across 21 items; 21 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

Install

How do I install the io.usefulapi/when-i-work MCP server?

io.usefulapi/when-i-work is a hosted endpoint at https://when-i-work.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.

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 →

Common questions

What is the io.usefulapi/when-i-work MCP server?

io.usefulapi/when-i-work is an MCP server listed in the public MCP registry as io.usefulapi/when-i-work. Check shifts, time clock entries, time-off requests, swaps and availability, and manage shifts. This page covers its hosted endpoint (https://when-i-work.usefulapi.io/mcp).

Is the io.usefulapi/when-i-work MCP server safe to use?

io.usefulapi/when-i-work scores 76 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/when-i-work MCP server expose?

io.usefulapi/when-i-work exposes 21 tools: wheniwork_get_account, wheniwork_list_users, wheniwork_get_user, wheniwork_list_locations, wheniwork_list_positions, and 16 more. Their descriptions and schemas cost roughly 3,676 tokens of context every time the server is loaded.

Does the io.usefulapi/when-i-work MCP server require authentication?

Yes. io.usefulapi/when-i-work 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/when-i-work MCP server still maintained?

io.usefulapi/when-i-work 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.
