# Install Lightsage MCP in OpenCode

> Connect OpenCode to Lightsage MCP with a remote MCP server entry.

OpenCode can connect to remote MCP servers from `opencode.json` or `opencode.jsonc`. Use this guide to connect OpenCode to the hosted Lightsage MCP endpoint.

<Steps>
  <Step title="Get your Lightsage API key">
    Open the [Lightsage dashboard](https://app.lightsage.com/settings/api), copy your API key, and store it as `LIGHTSAGE_API_KEY`:

    ```bash theme={null}
    export LIGHTSAGE_API_KEY="ls_cli_your_api_key"
    ```

    Do not put your API key in shared project config, screenshots, issue reports, or public repositories.
  </Step>

  <Step title="Add Lightsage MCP to OpenCode">
    Add Lightsage MCP to `opencode.json` or `opencode.jsonc`:

    ```jsonc theme={null}
    {
      "$schema": "https://opencode.ai/config.json",
      "mcp": {
        "lightsage": {
          "type": "remote",
          "url": "https://mcp.lightsage.com/mcp",
          "enabled": true,
          "oauth": false,
          "headers": {
            "X-Lightsage-Api-Key": "{env:LIGHTSAGE_API_KEY}"
          }
        }
      }
    }
    ```
  </Step>

  <Step title="Verify OpenCode can use Lightsage">
    Run OpenCode and ask it to use the `lightsage` MCP server. Use `opencode mcp list` if you need to inspect connection state.

    Then run a read-only prompt:

    ```text theme={null}
    Use the Lightsage MCP server to check my Lightsage auth status.
    ```
  </Step>
</Steps>

See the [OpenCode MCP docs](https://opencode.ai/docs/mcp-servers/) for local and remote server options.
