chore(deps): bump the python group across 1 directory with 2 updates

[dependabot]

Updates the requirements on mcp and structlog to permit the latest version.
Updates mcp to 2.0.0

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 structlog to 26.1.0

Release notes

Sourced from structlog's releases.

26.1.0

Highlights

Given how long this release took, it's pretty thicc with nice things all over the board! Apologies for the long release cycle; it's been a victim of the slopocalypse and me trying to navigate my way thru the new normal. Extra big thanks to my sponsors for not abandoning me in these unironically trying times. ❤️

Full changelog below!

Full Changelog

Removed

• Python 3.8 and 3.9 support.

Deprecated

• Support for better-exceptions is deprecated and will be removed within a year. Use our Rich integration or copy-paste the one line of code you need. #802

Added

• Python 3.15 support. #813

• structlog.dev.rich_monochrome_traceback for Rich-based monochrome exception rendering and add support for it throughout structlog.dev.ConsoleRenderer when the user asks for no colors. #794

• structlog.BytesLogger now has a name attribute which allows you to use it with the structlog.stdlib.add_logger_name() processor without using the standard library integration. #786

• structlog.processors.CallsiteParameterAdder now supports CallsiteParameter.QUAL_MODULE that adds the qualified import name of the module of the callsite, or __main__ if the module is the entry point. This is only available for structlog-originated events since the standard library has no equivalent (except for the convention of setting the logger's name to __name__). #812

• structlog.stdlib.BoundLogger now has is_enabled_for() and get_effective_level() methods that are snake_case aliases for its isEnabledFor() and getEffectiveLevel() methods. This makes it more compatible with the native structlog.typing.FilteringBoundLogger, so you can swap configurations without changing your call sites. #818

Changed

• structlog.dev.ConsoleRenderer does not warn anymore when the exception key has a rendered value despite having a fancy formatter configured. #790

Changed

• structlog.dev.ConsoleRenderer does not warn anymore when the exception key has a rendered value despite having a fancy formatter configured. #790

Fixed

• structlog.BytesLogger, structlog.PrintLogger, and structlog.WriteLogger now hold weak references to the files they use for output. This prevents their leakage in long-running processes that open many logfiles, such as task executors that create a per-task BytesLogger or WriteLogger. #807

• structlog.WriteLogger is usable after unpickling. #787

• structlog.processors.CallsiteParameterAdder now reports the calling thread's id and name for async log methods, instead of the thread from the executor pool that runs the underlying sync logger.
