Zed Date Math business_hours_deadline

How to: Zed Date Math business_hours_deadline

client:Zed transport:streamable-http tool:business_hours_deadline

Add Date Math to Zed

  1. 01

    Open ~/.config/zed/settings.json and merge this in. Keep any servers already there.

{
  "context_servers": {
    "date-math": {
      "url": "https://date-math.datemath.workers.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

    Ask for something business_hours_deadline does. Zed lists the server's tools on connect and calls business_hours_deadline itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Date Math's identifier in your config matches the one above exactly.

Merge this into your existing settings object — do not replace the file. Zed docs

Set these first

Date Math will not start until these are set, so business_hours_deadline never becomes available.

  • DATE_MATH_PRIVATE_KEY
  • DATE_MATH_MAX_PRICE

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
