WorkdayAPI is a remote MCP server (Streamable HTTP) at https://workdayapi.mike-tusa.workers.dev/mcp. Tools: get_holidays, is_business_day, add_business_days, business_days_between, list_countries.
Most MCP clients (Claude Desktop, Cursor, Cline, Windsurf) accept this config:
{
"mcpServers": {
"workdayapi": {
"type": "http",
"url": "https://workdayapi.mike-tusa.workers.dev/mcp"
}
}
}Clients that only support stdio can bridge with npx mcp-remote https://workdayapi.mike-tusa.workers.dev/mcp. VS Code uses a servers key instead of mcpServers.
The server.json file is the MCP Registry manifest for this server.
