[dependabot]

Updates click from 8.3.3 to 8.4.0

Release notes

Sourced from click's releases.

8.4.0

This is the Click 8.4.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecation, or introduce potentially breaking changes.

We encourage everyone to upgrade. You can read more about our Version Support Policy on our website.

PyPI: https://pypi.org/project/click/8.4.0/ Changes: https://click.palletsprojects.com/page/changes/#version-8-4-0 Milestone https://github.com/pallets/click/milestone/30

• ParamType typing improvements. #3371

  • :class:ParamType is now a generic abstract base class, parameterized by its converted value type.
  • :meth:~ParamType.convert return types are narrowed on all concrete types (str for :class:STRING, int for :class:INT, etc.).
  • :meth:~ParamType.to_info_dict returns specific :class:~typing.TypedDict subclasses instead of dict[str, Any].
  • :class:CompositeParamType and the number-range base are now generic with abstract methods.

• Refactor convert_type to extract type inference into a private _guess_type helper, and add :func:typing.overload signatures. #3372

• Parameter typing improvements. #2805

  • :class:Parameter is now an abstract base class, making explicit that it cannot be instantiated directly.
  • :attr:Parameter.name is now str instead of str | None. When expose_value=False, the name is set to "" instead of None.
  • The ctx parameter of :meth:Parameter.get_error_hint is now typed as Context | None, matching the runtime behavior.

• Split string values from default_map for parameters with nargs > 1 or :class:Tuple type, matching environment variable behavior. #2745 #3364

• Auto-detect type=UNPROCESSED for flag_value of non-basic types (not str, int, float, or bool), so programmer-provided Python objects like classes and enum members are passed through unchanged instead of being stringified. Previously type=click.UNPROCESSED had to be set explicitly. #2012 #3363

• The error hint now uses Command.get_help_option_names to pick non-shadowed help option names, so Try '... -h' no longer points to a subcommand option that shadows -h. All surviving names are shown (-h/--help). #2790 #3208

• Fix readline functionality on non-Windows platforms. Prompt text is now passed directly to readline instead of being printed separately, allowing proper backspace, line editing, and line wrapping behavior. #2968

Updates fastmcp from 3.2.4 to 3.3.1

Release notes

Sourced from fastmcp's releases.

v3.3.1: Loop There It Is

FastMCP 3.3.1 is a hotfix for the 3.3 packaging split. Clean installs of 3.3.0 could fail on standalone component imports like from fastmcp.tools import tool because component modules reached auth and task primitives through fastmcp.server, pulling in the server/provider stack and exposing a circular import.

Component-level auth and task primitives now live in lightweight utility modules, with the old server import paths preserved as compatibility re-exports. Component imports stay lightweight, existing server-facing imports continue to work, and the release also includes small docs corrections from the 3.3 rollout.

What's Changed

Fixes 🐞

• fix(docs): use valid FA icon on client-only package page by @​jlowin in PrefectHQ/fastmcp#4139
• Decouple component imports from server by @​jlowin in PrefectHQ/fastmcp#4150

Full Changelog: PrefectHQ/fastmcp@v3.3.0...v3.3.1

v3.3.0: Slim Reaper

FastMCP 3.3 ships fastmcp-slim, a new lightweight distribution that separates the client from the server stack. It also closes out a meaningful backlog of security hardening, observability improvements, and auth additions that accumulated through the 3.2 cycle.

fastmcp-slim

The full FastMCP package pulls in Starlette, Uvicorn, and the rest of the server machinery — necessary for running a server, but wasteful if you're writing a client, a script, or an agent that just needs to talk to MCP. fastmcp-slim is a dependency-light distribution that ships the client and transport layer without any of that.

The import namespace is unchanged:

from fastmcp import Client
async with Client("https://example.com/mcp") as client:
result = await client.call_tool("my_tool", {"arg": "value"})

Install fastmcp-slim[client] anywhere you want FastMCP's client without the server footprint — CI environments, lightweight agents, library dependencies that shouldn't force Uvicorn on downstream users.

Security

The OAuth proxy received three hardening upgrades. Silent consent is now guarded against AS-in-the-middle attacks — a malicious authorization server can no longer silently approve a consent it wasn't meant to handle. Redirect URI allowlist matching now rejects dot-segment paths (/../, /./) that could otherwise bypass prefix checks. And ResponseCachingMiddleware partitions its cache by access token, closing a gap where different users could see each other's cached responses.

Auth

AzureB2CProvider adds first-class support for Azure AD B2C user flows. The OCI provider is fixed for 3.x installs. And OAuthProxy gains a public update_scopes() API for updating the proxy's required scopes after initialization — useful for servers that determine scope requirements at runtime.

Observability

OTEL instrumentation is now fully compliant with MCP semantic conventions. List operations (list_tools, list_resources, list_prompts, list_resource_templates) are instrumented, and delegate spans on proxy servers are enriched with backend attributes.

Thread Affinity

Sync tools run in a thread pool by default. If your tool holds thread-local state or is bound to a specific thread (UI frameworks, some database drivers), you can now opt out:
