Bumps the uv group with 3 updates in the / directory: fastmcp, pytest and cryptography.

Updates fastmcp from 3.0.1 to 3.2.0

Release notes

Sourced from fastmcp's releases.

v3.2.0: Show Don't Tool

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.

FastMCPApp

FastMCPApp is a new provider class for building interactive applications inside MCP. It separates the tools the LLM sees (@app.ui()) from the backend tools the UI calls (@app.tool()), manages visibility automatically, and gives tool references stable identifiers that survive namespace transforms and server composition — without requiring host cooperation.

from fastmcp import FastMCP, FastMCPApp
from prefab_ui.actions.mcp import CallTool
from prefab_ui.components import Column, Form, Input, Button, ForEach, Text
app = FastMCPApp("Contacts")
@​app.tool()
def save_contact(name: str, email: str) -> list[dict]:
db.append({"name": name, "email": email})
return list(db)
@​app.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
mcp = FastMCP("Server", providers=[app])

The UI is built with Prefab, 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.

For simpler cases where you just want to visualize data without server interaction, set app=True on any tool and return Prefab components directly:

@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

Built-in Providers

Five ready-made providers you add with a single add_provider() call:

  • FileUpload — drag-and-drop file upload with session-scoped storage

v3.1.1: 'Tis But a Patch

Pins pydantic-monty below 0.0.8 to fix a breaking change in Monty that affects code mode. Monty 0.0.8 removed the external_functions constructor parameter, causing MontySandboxProvider to fail. This patch caps the version so existing installs work correctly.

Fixes 🐞

Full Changelog: v3.1.0...v3.1.1

v3.1.0: Code to Joy

FastMCP 3.1 is the Code Mode release. The 3.0 architecture introduced providers and transforms as the extensibility layer — 3.1 puts that architecture to work, shipping the most requested capability since launch: servers that can find and execute code on behalf of agents, without requiring clients to know what tools exist.

New Features 🎉

Updates pytest from 9.0.2 to 9.0.3

Release notes

Sourced from pytest's releases.

9.0.3

pytest 9.0.3 (2026-04-07)

Bug fixes

  • #12444: Fixed pytest.approx which now correctly takes into account ~collections.abc.Mapping keys order to compare them.

  • #13634: Blocking a conftest.py file using the -p no: option is now explicitly disallowed.

    Previously this resulted in an internal assertion failure during plugin loading.

    Pytest now raises a clear UsageError explaining that conftest files are not plugins and cannot be disabled via -p.

  • #13734: Fixed crash when a test raises an exceptiongroup with __tracebackhide__ = True.

  • #14195: Fixed an issue where non-string messages passed to unittest.TestCase.subTest() were not printed.

  • #14343: Fixed use of insecure temporary directory (CVE-2025-71176).

Improved documentation

  • #13388: Clarified documentation for -p vs PYTEST_PLUGINS plugin loading and fixed an incorrect -p example.
  • #13731: Clarified that capture fixtures (e.g. capsys and capfd) take precedence over the -s / --capture=no command-line options in Accessing captured output from a test function <accessing-captured-output>.
  • #14088: Clarified that the default pytest_collection hook sets session.items before it calls pytest_collection_finish, not after.
  • #14255: TOML integer log levels must be quoted: Updating reference documentation.

Contributor-facing changes

  • #12689: The test reports are now published to Codecov from GitHub Actions. The test statistics is visible on the web interface.

Updates cryptography from 46.0.5 to 46.0.7

Changelog

Sourced from cryptography's changelog.

46.0.7 - 2026-04-07


* **SECURITY ISSUE**: Fixed an issue where non-contiguous buffers could be
  passed to APIs that accept Python buffers, which could lead to buffer
  overflow. **CVE-2026-39892**
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.5.6.

.. _v46-0-6:

46.0.6 - 2026-03-25

  • SECURITY ISSUE: Fixed a bug where name constraints were not applied to peer names during verification when the leaf certificate contains a wildcard DNS SAN. Ordinary X.509 topologies are not affected by this bug, including those used by the Web PKI. Credit to Oleh Konko (1seal) for reporting the issue. CVE-2026-34073
