/**
 * Serves a harness as an MCP server, so any MCP client (Claude Code, Claude
 * Desktop, Cursor, another agent) can use it.
 *
 * The tools are `chat`, `steer`, `cancel`, `approve`, `reject`, `resolve`,
 * `answer`, and `status`, plus `agent_<name>` for each agent in
 * `harness.expose.agents`, `command_<name>` for each plugin command in
 * `harness.expose.commands`, and `tool_<name>` for each tool in
 * `harness.expose.tools`.
 * Every tool takes an optional `threadId`. Sessions open with
 * `host.open(harness, { threadId, user })`, so the host checks each
 * call. The `status` tool and the media resource only read: they use
 * `host.observe`, so they open no session and mount no plugins.
 *
 * Who makes the calls:
 *
 * - A host with `access`: the user that `access.getUser` finds for each
 *   HTTP request. `null` gets a 401. A refused action is a tool error. Each
 *   spec 2025 session belongs to its user, and `handle` replaces the
 *   `authInfo` of its options for that. Such a server needs HTTP: over stdio
 *   it throws. The server lists the agents of the harness definition, and
 *   no commands or agents of plugins, as it opens no session at the start.
 * - A host without `access`: the `openAccess` user, or no user
 *   with `openAccess: true`.
 *
 * The server throws at the start for a host without `access` and without
 * `openAccess`, and for a host with both.
 *
 * A result lists the open waits of its work in `waits`, each with its
 * `kind` (see `waitKind`): `approval`, `question`, `sign-in`,
 * `client-tool`, or `human`. `interrupts` are the waits of a stopped turn,
 * and `questions` the questions of the work. `approve` and `reject` answer
 * the approvals of the turn only. `resolve` answers the interrupts of the
 * turn, or the waits of a background agent run: `approved` for an
 * approval, and `payload` for the others. `answer` answers a question.
 *
 * `chat` takes `attachments`: `{ path }` (only inside `filePaths`),
 * `{ url, mimeType? }` (the model reads the URL, the server does not fetch
 * it), or `{ data, mimeType }` (base64). A result lists the media that the
 * work made in `media`. An image or audio file up to 5 MB comes back inline.
 * Any other file comes back as a `resource_link` to
 * `harness-media://<threadId>/<id>`, which `resources/read` returns.
 *
 * The result is the server from `createMCPServer`. Mount `server.fetch` on
 * an HTTP route, or pass the server to `serveMCPStdio`.
 *
 * @param options - The host, the harness, who the calls run as, the default thread, the approval mode, and the folders for `path` attachments
 *
 * @example
 * ```ts
 * const server = await createHarnessMcpServer({
 *   host,
 *   harness: assistant,
 *   openAccess: { user: { id: 'local-user' } },
 * })
 * serveMCPStdio(server)
 * ```
