description: Add local and remote MCP tools.
---

You can add external tools to opencode using the _Model Context Protocol_, or MCP. opencode supports both:

- Local servers
- And remote servers

Once added, MCP tools are automatically available to the LLM alongside built-in tools.

---

## Configure

You can define MCP servers in your opencode config under `mcp`.

### Local

Add local MCP servers under `mcp` with `"type": "local"`.

```json title="opencode.json"
{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "my-local-mcp-server": {
      "type": "local",
      "command": ["bun", "x", "my-mcp-command"],
      "enabled": true,
      "environment": {
        "MY_ENV_VAR": "my_env_var_value"
      }
    }, {
    "my-different-local-mcp-server": {
      "type": "local",
      "command": ["bun", "x", "my-other-mcp-command"],
      "enabled": true
    }
  }
}
```

You can also disable a server by setting `enabled` to `false`. This is useful if you want to temporarily disable a server without removing it from your config.

### Remote

Add remote MCP servers under `mcp` with `"type": "remote"`.

```json title="opencode.json"
{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "my-remote-mcp": {
      "type": "remote",
      "url": "https://my-mcp-server.com",
      "enabled": true,
      "headers": {
        "Authorization": "Bearer MY_API_KEY"
      }
    }
  }
}
```
