To ensure consistent access and better account management, we have updated the supported authentication flow for mabl MCP users. Starting with mabl CLI version 2.74.0, API key auth is no longer supported for the mabl MCP. All mabl MCP users must authenticate via the mabl CLI by using mabl auth login and providing their user credentials.
If you already authenticate using mabl auth login, you are not impacted by this change. If you previously configured your mabl MCP by including an API key in the "args" section, please make sure to remove it from your configuration.
Moving forward, your mabl MCP config should contain the following details:
{
"mcpServers": {
"mabl": {
"command": "npx",
"args": [
"@mablhq/mabl-cli@latest",
"mcp",
"start"
]
}
}
}
