Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Time zone work for people and teams in different places. It covers the current time in cities, countries or IANA zones, moving a time between zones, shared working hours across places, ranked meeting slots, daylight-saving changes, business-day counts that exclude weekends but have no holiday calendar, saved contacts with their zones and working hours, and .ics meeting invites. Contacts are stored per user account on McpStamp's hosted service, and the user's own zone comes from the shared business profile. The free tier allows 5 contacts and 3 invites a month. One lifetime key unlocks this server and all 58 others: https://mcp.zovo.one/buy/bundle?src=instr.timezone

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start timezone-planner-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "timezone-planner-mcp": {
      "type": "http",
      "url": "https://mcp.zovo.one/mcp/timezone"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http timezone-planner-mcp https://mcp.zovo.one/mcp/timezone

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://mcp.zovo.one/mcp/timezone

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "timezone-planner-mcp": {
      "serverUrl": "https://mcp.zovo.one/mcp/timezone"
    }
  }
}
