# `fastmcp.cli.apps_dev`
Dev server for previewing FastMCPApp UIs locally.
Starts the user's MCP server on a configurable port, then starts a lightweight
Starlette dev server that:
- Serves a Prefab-based tool picker at GET /
- Proxies /mcp to the user's server (avoids browser CORS restrictions)
- Serves the AppBridge host page at GET /launch
The host page uses @modelcontextprotocol/ext-apps to connect to the MCP server
and render the selected UI tool inside an iframe.
Startup sequence
----------------
1. Download ext-apps app-bridge.js from npm and patch its bare
``@modelcontextprotocol/sdk/…`` imports to use concrete esm.sh URLs.
2. Detect the exact Zod v4 module URL that esm.sh serves for that SDK version
and build an import-map entry that redirects the broken ``v4.mjs`` (which
only re-exports ``{z, default}``) to ``v4/classic/index.mjs`` (which
correctly exports every named Zod v4 function). Import maps apply to the
full module graph in the document, including cross-origin esm.sh modules.
3. Serve both the patched JS and the import-map JSON from the dev server.

```python
run_dev_apps(server_spec: str) -> None
```
Start the full dev environment for a FastMCPApp server.
Starts the user's MCP server on *mcp_port*, starts the Prefab dev UI
on *dev_port* (with an /mcp proxy to the user's server), then opens
the browser.

All components returned by this provider have task_config.mode="forbidden"
because tasks cannot be executed through a proxy.
Component lists (tools, resources, templates, prompts) are cached so that
individual lookups (e.g. during ``call_tool``) can resolve from the cache
instead of opening a new backend connection. The cache stores the
backend's raw component metadata and is shared across all sessions;
per-session visibility and auth filtering are applied after cache lookup
by the server layer. The cache is refreshed whenever a ``list_*`` call
is made, and entries expire after ``cache_ttl`` seconds (default 300).
Set ``cache_ttl=0`` to disable caching. Disabling is recommended for
backends whose component lists change dynamically.

Transform that adds tools for listing and getting prompts.
Generates two tools:
- `list_prompts`: Lists all prompts from the provider
- `list_prompts`: Lists all prompts
- `get_prompt`: Gets a specific prompt with optional arguments
The transform captures a provider reference at construction and queries it
for prompts when the generated tools are called. When used with FastMCP,
the provider's auth and visibility filtering is automatically applied.
The generated tools route through the server at runtime, so auth,
middleware, and visibility apply automatically.
