Bumps [fastmcp](https://github.com/PrefectHQ/fastmcp) from 3.1.1 to 3.2.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/PrefectHQ/fastmcp/releases">fastmcp's releases</a>.</em></p> <blockquote> <h2>v3.2.0: Show Don't Tool</h2> <p>FastMCP 3.2 is the Apps release. The 3.0 architecture gave you providers and transforms; 3.1 shipped Code Mode for tool discovery. 3.2 puts a face on it: your tools can now return interactive UIs — charts, dashboards, forms, maps — rendered right inside the conversation.</p> <h2>FastMCPApp</h2> <p><code>FastMCPApp</code> is a new provider class for building interactive applications inside MCP. It separates the tools the LLM sees (<code>@app.ui()</code>) from the backend tools the UI calls (<code>@app.tool()</code>), manages visibility automatically, and gives tool references stable identifiers that survive namespace transforms and server composition — without requiring host cooperation.</p> <pre lang="python"><code>from fastmcp import FastMCP, FastMCPApp from prefab_ui.actions.mcp import CallTool from prefab_ui.components import Column, Form, Input, Button, ForEach, Text <p>app = FastMCPApp("Contacts")</p> <p><a href="https://github.com/app"><code>@app</code></a>.tool() def save_contact(name: str, email: str) -> list[dict]: db.append({"name": name, "email": email}) return list(db)</p> <p><a href="https://github.com/app"><code>@app</code></a>.ui() def contact_manager() -> PrefabApp: with PrefabApp(state={"contacts": list(db)}) as view: with Column(gap=4): ForEach("contacts", lambda c: Text(c.name)) with Form(on_submit=CallTool("save_contact")): Input(name="name", required=True) Input(name="email", required=True) Button("Save") return view</p> <p>mcp = FastMCP("Server", providers=[app]) </code></pre></p> <p>The UI is built with <a href="https://prefab.prefect.io">Prefab</a>, a Python component library that compiles to interactive UIs. You write Python; the user sees charts, tables, forms, and dashboards. FastMCP handles the MCP Apps protocol machinery — renderer resources, CSP configuration, structured content serialization — so you don't have to.</p> <p>For simpler cases where you just want to visualize data without server interaction, set <code>app=True</code> on any tool and return Prefab components directly:</p> <pre lang="python"><code>@mcp.tool(app=True) def revenue_chart(year: int) -> PrefabApp: with PrefabApp() as app: BarChart(data=revenue_data, series=[ChartSeries(data_key="revenue")]) return app </code></pre> <h2>Built-in Providers</h2> <p>Five ready-made providers you add with a single <code>add_provider()</code> call:</p> <ul> <li><strong>FileUpload</strong> — drag-and-drop file upload with session-scoped storage</li> </ul>  </blockquote> <p>...
