Release notes

Sourced from mcp's releases.

v2.0.0

MCP Python SDK v2 Stable Release

This is v2.0.0, the stable v2 release of the MCP Python SDK. It supports the 2026-07-28 revision of the Model Context Protocol and serves every earlier revision from the same server. pip install mcp now installs 2.x.

pip install "mcp[cli]"
# or
uv add "mcp[cli]"

Documentation Rewrite

The documentation has the full tutorial and API reference. Coming from v1? What's new in v2 is the tour of what changed and why, and the migration guide lists every breaking change with before-and-after code.

V1 Maintenance mode

v1.x is in maintenance mode and will only receive security fixes from now on The 1.x line lives on the v1.x branch, continues to receive critical bug fixes and security patches, and is documented at https://py.sdk.modelcontextprotocol.io/v1/. If your project is not ready to migrate, keep a <2 upper bound on your requirement (for example mcp>=1.28,<2).

Highlights

One SDK, both protocol eras

v2 speaks the 2026-07-28 revision (stateless requests with no handshake, server/discover, subscriptions/listen, multi-round-trip requests) and still serves every 2025-era client from the same MCPServer, over Streamable HTTP and stdio, with nothing to configure. Client(target) negotiates the version automatically.

FastMCP is now MCPServer, and there is a first-class Client

The decorator API is unchanged; the low-level Server is rebuilt around a shared dispatcher engine, and one Client object replaces v1's transport-plus-ClientSession-plus-initialize() layering. It connects to a URL, a stdio subprocess, a custom transport, or straight to a server object in memory for tests.

Multi-round-trip requests and resolver dependency injection

At 2026-07-28 the server can no longer call the client, so tools return the question instead. A Resolve(fn) parameter is filled by your function invisibly to the model and can put a question to the user; one tool body serves both eras.

Extension APIs, OpenTelemetry, and a standalone types package

Servers and clients compose protocol extensions through pluggable extension APIs (MCP Apps built in); OpenTelemetry tracing ships on by default; every protocol type is its own package, mcp-types (imported as mcp_types), published in lock-step with mcp.

Hardened stdio and auth

stdio servers keep handler subprocesses and stray prints off the wire, and stdout is diverted to stderr while serving. OAuth adds RFC 9207 issuer validation, the SEP-990 identity-assertion flow, and the client-credentials extension.

Coming from a v2 pre-release

Since the last release candidate: the per-version wire packages are private (mcp_types._v*), mcp.types is a permanent alias for mcp_types, the auth registration request model is split from the registered-client record, cancelled requests are no longer answered, and log notifications are gated on the per-request log-level opt-in at 2026-07-28. Since the betas: Client(cache=False) is now cache=None with CacheConfig() the default; Context.client_id, RFC7523OAuthClientProvider, and OAuthClientProvider(timeout=) are removed; the client-credentials providers take scope=; message_handler receives notifications and exceptions only; FileResource(is_binary=) becomes encoding; MCP_* env vars are gone with pydantic-settings; Streamable HTTP servers reject bodies over 4 MiB with HTTP 413. The migration guide covers all of it.

Known gaps

The tasks extension (SEP-2663) is not part of this release. On the client, the DPoP proof binding (SEP-1932) and the workload-identity jwt-bearer grant are not implemented; both are additive and can land in 2.x.

Updates cryptography from 48.0.1 to 50.0.0

Changelog

Sourced from cryptography's changelog.

50.0.0 - 2026-07-31

* **SECURITY ISSUE**:
  :func:`~cryptography.hazmat.primitives.serialization.pkcs7.pkcs7_decrypt_der`
  and its PEM and S/MIME variants no longer expose distinguishable errors or
  timing when unwrapping a ``RecipientInfo``'s ``encryptedKey``, which could
  act as a Bleichenbacher oracle for callers that decrypt untrusted messages.
  A random key is now substituted on failure, as described in :rfc:`3218`.
  Credit to **@X1AOxiang** for reporting the issue. **CVE-2026-69247**
* Deprecated Diffie-Hellman key exchange over finite fields (FFDH).
  Everything FFDH is deprecated, including the types in
  ``cryptography.hazmat.primitives.asymmetric.dh`` and loading FFDH keys or
  parameters with the key loading APIs. Users should migrate to a more
  modern key exchange algorithm.
* Added ``xof()`` class methods to
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE128` and
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE256` for constructing
  algorithm instances configured for use with
  :class:`~cryptography.hazmat.primitives.hashes.XOFHash`.
* The :mod:`X.509 verification <cryptography.x509.verification>` APIs are now
  considered stable and are subject to our API stability policy.
* Added the :doc:`/cobblestone` recipe, an implementation of the
  Cobblestone-128 and Cobblestone-256 instantiations of the `C2SP
  chunked-encryption specification
  <https://c2sp.org/chunked-encryption>`_ for streaming authenticated
  encryption of large messages.
* Parsing a Signed Certificate Timestamp list now rejects encodings that
  carry trailing bytes after the list or after an individual SCT, instead of
  silently ignoring them.
* Added support for using :class:`~cryptography.x509.Name` as a field type in
  the :doc:`/hazmat/asn1/index` module.
* Loading a public key or an EC private key now rejects DER where the
  ``subjectPublicKey`` (or EC ``publicKey``) ``BIT STRING`` declares a non-zero
  number of unused bits, instead of silently ignoring it.
* Parsing a CRL entry's ``InvalidityDate`` extension now rejects a
  ``GeneralizedTime`` that carries fractional seconds or another non-DER form,
  matching the strict encoding already required for every other X.509 time
  field.
* :func:`~cryptography.x509.ocsp.load_der_ocsp_request` and
  :func:`~cryptography.x509.ocsp.load_der_ocsp_response` now reject a request
  or response whose ``version`` field is not ``v1``, the only version defined
  by RFC 6960, matching the version validation already performed when loading
  certificates, CSRs and CRLs.
* :class:`~cryptography.hazmat.primitives.hashes.XOFHash` is now supported
  when building against AWS-LC.
* HMAC (and therefore PBKDF2-HMAC) with SHA-3 hashes is now supported when
  building against AWS-LC.
* Diffie-Hellman (:doc:`/hazmat/primitives/asymmetric/dh`) is now supported
  when building against AWS-LC.

3.32.2 (2026-07-29)

---

• A SoftReadWriteLock or SoftFileLease acquire whose heartbeat thread fails to start now unlinks its marker and hands the claim back, instead of leaving an unrefreshed marker a peer takes while the caller believes it still holds the lock. :pr:691

---

3.32.1 (2026-07-26)

---

• Canceling an AsyncSoftReadWriteLock acquire now releases the claim instead of leaking a marker whose heartbeat wedges every contender. :pr:686

---

3.32.0 (2026-07-21)

---

• SoftReadWriteLock closes the directory handle it opens to scan for readers as soon as a scan stops early, rather than holding it until the generator is collected. :pr:685
• Declare support for Python 3.15 and run the test suite against it and its free-threaded build, both currently in beta. :pr:683
• The source distribution ships the capability probes the tests import, and reading one no longer needs coverage installed, so the suite runs from an unpacked sdist instead of failing on a missing coverage_pragmas. :pr:685

---

3.31.2 (2026-07-21)

---

• filelock imports again on runtimes whose errno omits ENOTSUP, such as GraalPy, where importing the package raised ImportError. It probes the code instead, preferring ENOTSUP, falling back to EOPNOTSUPP where that name is absent, and dropping to ENOSYS/EXDEV where neither exists. Platforms defining ENOTSUP keep their behavior. :pr:681

---

3.31.1 (2026-07-20)

---

• A SoftFileLease acquired on one thread keeps its claim when another thread fails to acquire the same lease object, so its heartbeat carries on refreshing the marker instead of being torn down and letting a peer take the live claim. :pr:680

Updates click from 8.4.1 to 8.4.2

Release notes

Sourced from click's releases.

8.4.2

This is the Click 8.4.1 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/click/8.4.2/ Changes: https://click.palletsprojects.com/page/changes/#version-8-4-2 Milestone: https://github.com/pallets/click/milestone/34

• Fix Fish shell completion broken in 8.4.0 by #3126. Newlines and tabs in option help text are now escaped, keeping the original completion format while still supporting multi-line help. #3502 #3043 #3504 #3508
• Deprecated commands and options with empty or missing help text no longer render a stray leading space before the (DEPRECATED) label. #3509
• A {class}Group with invoke_without_command=True marks its subcommand as optional in the usage help, showing [COMMAND] instead of COMMAND. #3059 #3507
• echo_via_pager flushes after each write, so passing a generator streams output to the pager incrementally instead of staying hidden until the pipe buffer fills. #3242 #2542 #3534
• echo_via_pager and get_pager_file no longer close a borrowed stdout stream when no external pager runs, completing the partial I/O operation on closed file fix from #3482. #3449 #3533
• Fix CLI usage symopsis for optional arguments producing double square brackets [[a|b|c]]... whose type already brackets their metavar. #3578
• {func}version_option resolves a package_name that does not match an installed distribution as an import (top-level module) name via {func}importlib.metadata.packages_distributions. Packages whose top-level module name differs from their distribution name (PIL vs Pillow, jwt vs PyJWT) no longer raise RuntimeError out of the box. #2331 #1884 #3125 #3582

Updates uvicorn from 0.48.0 to 0.52.1

Release notes

Sourced from uvicorn's releases.

Version 0.52.1

Fixed

• Complete the closing handshake on server-initiated WebSocket closes in the websockets-sansio and wsproto implementations, waiting for the client's close reply with a 10 second timeout instead of resetting the connection (#3053)
• Add missing write flow control to the websockets-sansio implementation, preventing data truncation on server-initiated closes with large in-flight payloads (#3048)
• Handle connection loss while a WebSocket write is waiting on backpressure (#3050)
• Remove duplicate Content-Type and Content-Length headers from WebSocket denial responses on the websockets-sansio implementation, and deliver non-UTF-8 denial bodies intact (#3041)

Full Changelog: Kludex/uvicorn@0.52.0...0.52.1

Version 0.52.0

This release adds an experimental HTTP/1.1 implementation backed by zttp, a sans-IO HTTP parser I've been developing on the side: a core written in Zig, with bindings to Python. It has been running under a fuzzer for some weeks now, and has been through multiple rounds of security auditing.

It is still experimental, so don't put it in front of production traffic yet. Try it with --http zttp, and please send any feedback to the issue tracker.

Added

• Add an experimental zttp HTTP/1.1 implementation, selectable with --http zttp (#2979)

Fixed

• Keep non-ASCII WebSocket request headers intact with websockets 17.0, which encodes them with ISO-8859-1 (#3036)

Full Changelog: Kludex/uvicorn@0.51.0...0.52.0

Version 0.51.0

What's Changed

• Restart workers with overlap on SIGHUP for near-zero-downtime reloads by @​Kludex in Kludex/uvicorn#3025
• Remove colorama from the standard extra by @​Kludex in Kludex/uvicorn#3027

Full Changelog: Kludex/uvicorn@0.50.2...0.51.0

Version 0.50.1

What's Changed

• Split comma-separated Sec-WebSocket-Protocol values in the websockets-sansio implementation by @​Aayush7352 in Kludex/uvicorn#3019

New Contributors

• @​Aayush7352 made their first contribution in Kludex/uvicorn#3019

Full Changelog: Kludex/uvicorn@0.50.0...0.50.1

Version 0.50.0

What's Changed

• Memoize trusted host checks to avoid re-parsing the client IP per request by @​Kludex in Kludex/uvicorn#2970
• Cache the asgi scope sub-dict per connection by @​Kludex in Kludex/uvicorn#2976
• Build a fresh asgi scope dict per request by @​Kludex in Kludex/uvicorn#2977
• Replace click.style with an internal ANSI style helper by @​Kludex in Kludex/uvicorn#2981
• Avoid copying single-frame WebSocket payloads in websockets-sansio by @​Kludex in Kludex/uvicorn#2983

0.51.0 (July 8, 2026)

Added

• Restart workers one at a time on SIGHUP, bringing each replacement up before retiring the old worker, so reloads no longer drop requests (#3025)

Removed

• Remove colorama from the standard extra (#3027)

0.50.2 (July 6, 2026)

Fixed

• Require websockets>=13.0, which the default websockets-sansio implementation needs (#3021)

0.50.1 (July 6, 2026)

Fixed

• Split comma-separated Sec-WebSocket-Protocol values in the websockets-sansio implementation (#3019)

0.50.0 (July 4, 2026)

If you use WebSockets, note that --ws auto now picks the websockets-sansio implementation. You shouldn't need it, but you can pin --ws websockets to get the deprecated legacy one back.

Updates pytest from 9.0.3 to 9.1.1

Release notes

Sourced from pytest's releases.

9.1.1

pytest 9.1.1 (2026-06-19)

Bug fixes

• #14220: Fixed a logic bug in pytest.RaisesGroup which would might cause it to display incorrect "It matches FooError() which was paired with BarError" messages.
• #14591: Fixed a regression in pytest 9.1.0 which caused overriding a parametrized fixture with an indirect @​pytest.mark.parametrize to fail with "duplicate parametrization of '<fixture name>'".
• #14606: Fixed list-item typing errors from mypy in @pytest.mark.parametrize <pytest.mark.parametrize ref> argvalues parameter.
• #14608: Fixed a regression in pytest 9.1.0 where conftest.py files located in <invocation dir>/test* were no longer loaded as initial conftests when invoked without arguments. This could cause certain hooks (like pytest_addoption) in these files to not fire.

9.1.0

pytest 9.1.0 (2026-06-13)

Removals and backward incompatible breaking changes

• #14533: When using --doctest-modules, autouse fixtures with module, package or session scope that are defined inline in Python test modules (not plugins or conftests) will now possibly execute twice.

  If this is undesirable, move the fixture definition to a conftest.py file if possible.

  Technical explanation for those interested: When using --doctest-modules, pytest possibly collects Python modules twice, once as pytest.Module and once as a DoctestModule (depending on the configuration). Due to improvements in pytest's fixture implementation, if e.g. the DoctestModule collects a fixture, it is now visible to it only, and not to the Module. This means that both need to register the fixtures independently.

Deprecations (removal in next major release)

• #10819: Added a deprecation warning for class-scoped fixtures defined as instance methods (without @classmethod). Such fixtures set attributes on a different instance than the test methods use, leading to unexpected behavior. Use @classmethod decorator instead -- by yastcher.

  See 10819 and 14011.

• #12882: Calling request.getfixturevalue() <pytest.FixtureRequest.getfixturevalue> during teardown to request a fixture that was not already requested is now deprecated and will become an error in pytest 10.

  See dynamic-fixture-request-during-teardown for details.

• #13409: Using non-~collections.abc.Collection iterables (such as generators, iterators, or custom iterable objects) for the argvalues parameter in @pytest.mark.parametrize <pytest.mark.parametrize ref> and metafunc.parametrize <pytest.Metafunc.parametrize> is now deprecated.

  These iterables get exhausted after the first iteration, leading to tests getting unexpectedly skipped in cases such as running pytest.main() multiple times, using class-level parametrize decorators, or collecting tests multiple times.

  See parametrize-iterators for details and suggestions.

• #13946: The private config.inicfg attribute is now deprecated. Use config.getini() <pytest.Config.getini> to access configuration values instead.

  See config-inicfg for more details.

• #14004: Passing baseid to ~pytest.FixtureDef or nodeid strings to fixture registration APIs is now deprecated. These are internal pytest APIs that are used b...
