# Model Settings

> Configure default agents, provider keys, custom MCP servers, and model availability.

Use **Settings > Models** in the [dashboard](https://app.tembo.io) to control how your workspace selects and runs models.

## Default agent

Set the default agent and model Tembo uses for new tasks and automations.

* Pick the default from a single dropdown in **Settings > Models**
* You can still override agent/model per task or automation

## Provider API keys

You can manage model provider credentials in one place:

* Anthropic API key
* OpenAI API key
* Amp API key
* Cursor API key
* AWS Bedrock access key, secret key, and region

Keys are saved at the workspace level and used when a selected model requires that provider.

## Custom MCP servers (global JSON)

`globalMcpServers` lets you define shared MCP servers available across tasks and automations.

```json theme={null}
{
  "mcpServers": {
    "my-server": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_TOKEN": "your-github-token"
      }
    }
  }
}
```

<Note>
  This JSON is workspace-wide. Invalid JSON is rejected when you save.
</Note>

## Available models

The **Available Models** list lets you enable or disable specific models for your organization.

* Models are enabled by default
* Org admins can toggle models on/off
* Non-admin members can view status but cannot change it

<Warning>
  You cannot disable the model currently used by your default agent. Change the default agent model first.
</Warning>
