 - Run `bun run dev:live` from a development worktree to test its TUI against the currently elected `opencode2` background server and live sessions.
 - Pass a directory after the script when needed, for example `bun run dev:live /path/to/project`.
-- The script discovers the server with `opencode2 service status`, injects its private local credential from `opencode2 service get password`, and uses the `next` TUI storage channel so tabs and other client-local state match the installed client.
+- The script discovers the server with `opencode2 service status`, injects its private local credential from `opencode2 service get password`, and uses the `dev` TUI storage channel so tabs and other client-local state match the installed client.
 - Prefer `dev:live` over plain `bun run dev` for this workflow. An implicit managed-service connection may replace the live server when the worktree client version differs; explicit `--server` warns and continues without replacing it.

+Configure MCP servers under `mcp.servers`. Prefer the CLI because it preserves

+The auth command prints an authorization URL, waits for the browser redirect,
+and stores credentials outside the OpenCode configuration. Do not ask for or
+store an API key when the server supports OAuth. Use header-based credentials
+only when OAuth is unavailable or the user explicitly requires them, and use an
+environment substitution such as `{env:MCP_API_KEY}` instead of writing a
+secret into configuration.

 ## [V1 to V2 migration](https://opencode.ai/v2/docs/migrate-v1)
 
 For any request to migrate OpenCode configuration, agents, commands, skills,
 plugins, integrations, or other behavior from V1 to V2, read the full
 [migration guide](https://opencode.ai/v2/docs/migrate-v1) before acting. In
-the repository, its source is `packages/www/content/docs/(Get started)/migrate-v1.mdx`.
+the repository, its source is `packages/www/content/docs/migrate-v1.mdx`.
 
 V1 config files and `.opencode/` definitions are intended to remain compatible.
 The only intentional breaking changes are the server API and plugin API. Native
