Worth a look

  • Tools that change data, on a server that answers without a sign-in: overtime_pay

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • calculate_time_card

    Adds up a time card (up to 14 days, 7 per workweek) from start and end times in 24-hour HH:MM, subtracting unpaid breaks; shifts past midnight are handled. Splits overtime per workweek under US federal law (over 40 hours, 1.5x) or under…

  • convert_decimal_hours

    Converts hours and minutes (H:MM) to decimal hours, or decimal hours to hours and minutes. 7:45 is 7.75 hours.

  • overtime_pay

    Regular, overtime and double-time pay from an hourly rate and hours. Overtime multiplier defaults to 1.5 (US federal minimum for covered, non-exempt work over 40 hours a week); double time is 2x.

  • split_tip_pool

    Splits a tip pool by hours worked, rounded to the cent so the shares add up exactly to the total.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "calculators": {
      "type": "http",
      "url": "https://paycheckhours.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http paycheckhours https://paycheckhours.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://paycheckhours.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
