Windsurf Date Math subscription_dates
How to: Windsurf Date Math subscription_dates
Add Date Math to Windsurf
-
01
Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"date-math": {
"serverUrl": "https://date-math.datemath.workers.dev/mcp"
}
}
}-
02
Save the file and restart Windsurf.
-
03
Ask for something subscription_dates does. Windsurf lists the server's tools on connect and calls subscription_dates itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that Date Math's identifier in your config matches the one above exactly.
Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs
Set these first
Date Math will not start until these are set, so subscription_dates 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.
