Updates the requirements on fastmcp, mcp, python-dotenv, pypdf, pillow and ruff to permit the latest version.
Updates fastmcp to 4.1.3

Release notes

Sourced from fastmcp's releases.

v4.1.3: Root Awakening

This release updates certifi-backed dependencies following the eMudhra CA compromise and fixes public-client OAuth authentication, empty visibility selections, generator transforms, and per-server timeouts for ordinary requests. FastMCP 4 uses system trust by default: follow the security notice to update operating-system, container, custom, and installer trust stores; upgrading FastMCP alone is insufficient. Thanks to our 11 contributors, including 6 first-time contributors.

What's Changed

Security 🔒

  • Require certifi 2026.10.19 or later for certifi-backed server dependencies and optional SDK integrations, and document system, custom, and installer trust-store updates by @​zzstoatzz in PrefectHQ/fastmcp#5945.

Full Changelog: v4.1.2...v4.1.3

v4.1.2: License to Deny

Component authorization now applies after transforms, denied resources cannot fall through matching templates, and OAuth client credentials providers support issuer binding across fresh and cached-token flows. Existing configurations remain compatible, but users of ClientCredentialsOAuthProvider or PrivateKeyJWTOAuthProvider must set issuer to enable this protection; upgrading alone is insufficient. Thanks to our 18 contributors, including 9 first-time contributors.

Updates mcp to 2.3.0

Release notes

Sourced from mcp's releases.

v2.3.0

pip install -U mcp. Docs: https://py.sdk.modelcontextprotocol.io/

Mostly fixes, plus three new options. A few things behave differently, so skim these first:

Behaviour changes

httpx2>=2.10.0 is now required (#3600)

  • It was >=2.5.0. The new max_sse_event_size option needs it.
  • Nothing to do unless you pin httpx2 below 2.10.

A tool with an invalid x-mcp-header annotation fails at registration (#3620)

  • @mcp.tool(), add_tool and Tool.from_function raise InvalidSignature, naming the tool and the problem.
  • Until now the server started, and 2026-07-28 clients silently dropped the tool from their listing.
  • Refused: anything other than a plain str, int or bool parameter (so also str | None, float, lists and enums), a header name that isn't a valid token, and two names that differ only by case.
  • For an optional header parameter, give the schema directly: Annotated[str | None, WithJsonSchema({"type": "string", "x-mcp-header": "Region"})] = None.

Empty _meta and params are no longer sent (#3628)

  • On 2025-11-25 and earlier connections, 2.x sent "_meta": {} on every request. Some servers reject that. It is now left out, as in v1.
  • ping and list requests without a cursor go out with no params member.
  • On the receiving side ctx.meta is None rather than {}, and middleware sees ctx.params as None for a request without params.
  • 2026-07-28 connections are unchanged.

initialize leaves out experimental when none is configured (#3614)

  • It used to send "experimental": {}. server/discover already left it out.
  • Client code reading capabilities.experimental on a legacy connection should handle None.

Mcp-Param-* validation looks the tool up by name (#3630)

  • MCPServer no longer runs tools/list for every tools/call, so middleware no longer sees that extra request.
  • The registered schema is what gets checked. Middleware that filters or rewrites tools/list no longer affects it.

An interactive OAuth login no longer counts against request timeouts (#3635)

  • The timeout pauses while OAuthClientProvider waits on redirect_handler and callback_handler.
  • This fixes Client(mode="auto") settling on 2025-11-25 when the login took longer than 10 seconds.
  • A request timeout no longer ends a login nobody finishes. Put a limit inside callback_handler if you need one.

New

  • max_sse_event_size= on streamable_http_client and StreamableHttpParameters. The default stays 1 MiB per SSE event; raise it, or pass None, for larger tool results (#3600).
  • MCPServer(subscriptions=False) stops serving subscriptions/listen and advertises listChanged and subscribe as false (#3626).
  • Server(get_tool_input_schema=...) lets a low-level server supply a tool's schema for header validation without running its tools/list handler (#3630).
  • Client.call_tool re-lists the tools and retries once after a HeaderMismatch (-32020) rejection (#3627).

Fixes

  • ctx: Context[AppState] works on prompts and resource templates, not only on tools (#3624).
  • An explicit "structuredContent": null is checked against the output schema instead of being treated as missing (#3621).
  • A progress_callback that raises no longer fails the call on an in-process Client(server) (#3623).
  • Client OpenTelemetry spans record JSON-RPC error responses. With mode="auto", connecting to a server without server/discover now shows one ERROR span for the probe (#3629).
  • stdio_client resolves the executable off the event loop on Windows (#3510).

Updates python-dotenv to 1.2.4

Release notes

Sourced from python-dotenv's releases.

v1.2.4

Fixed

  • dotenv get no longer exits with code 1 for empty string values (KEY=) by [@​ShamikOfficial] in #700
  • An unquoted empty value followed by an inline comment (e.g. KEY= # comment) is now parsed as an empty string instead of the comment text by [@​Noethix55555] in #663
  • dotenv run --no-override now expands variable references with the same precedence as load_dotenv(override=False), so a value like ${BASE}/suffix uses the existing BASE from the environment instead of the one from the .env file by [@​ROTl24] in #698
Changelog

Sourced from python-dotenv's changelog.

[1.2.4] - 2026-10-01

Fixed

  • dotenv get no longer exits with code 1 for empty string values (KEY=) by [@​ShamikOfficial] in #700
  • An unquoted empty value followed by an inline comment (e.g. KEY= # comment) is now parsed as an empty string instead of the comment text by [@​Noethix55555] in #663
  • dotenv run --no-override now expands variable references with the same precedence as load_dotenv(override=False), so a value like ${BASE}/suffix uses the existing BASE from the environment instead of the one from the .env file by [@​ROTl24] in #698

[1.2.3] - 2026-08-16

Fixed

  • Strip a leading UTF-8 BOM from .env file contents so the first variable is no longer silently lost when the file is saved with BOM (e.g. by some JetBrains IDEs on Windows) by [@​h1whelan] in #640
  • set_key now escapes backslashes, so values containing them (Windows paths, regular expressions) survive a write/read round-trip. Quoted values ending in an escaped backslash are no longer mis-parsed as an escaped quote, which used to swallow the following lines by [@​dchaudhari7177] in #680
  • dotenv run now prints a friendly error instead of a traceback when no command is given by [@​bbc2] in #606
  • Cache the parsed result for empty .env files so repeated dotenv_values/load_dotenv calls no longer re-read the file by [@​ReinerBRO] in #638

[1.2.2] - 2026-03-01

Added

  • Support for Python 3.14, including the free-threaded (3.14t) build. (#588)

Changed

  • The dotenv run command now forwards flags directly to the specified command by [@​bbc2] in #607
  • Improved documentation clarity regarding override behavior and the reference page.
  • Updated PyPy support to version 3.11.
  • Documentation for FIFO file support.
  • Dropped Support for Python 3.9.

Fixed

  • Improved set_key and unset_key behavior when interacting with symlinks by [@​bbc2] in [790c5c0]
  • Corrected the license specifier and added missing Python 3.14 classifiers in package metadata by [@​JYOuyang] in #590

Breaking Changes

  • dotenv.set_key and dotenv.unset_key used to follow symlinks in some situations. This is no longer the case. For that behavior to be restored in all cases, follow_symlinks=True should be used.

  • In the CLI, set and unset used to follow symlinks in some situations. This is no longer the case.

  • dotenv.set_key, dotenv.unset_key and the CLI commands set and unset used to reset the file mode of the modified .env file to 0o600 in some situations. This is no longer the case: The original mode of the file is now preserved. Is the file needed to be created or wasn't a regular file, mode 0o600 is used.

0.17.0

Released on 2026-10-09.

The executables in our macOS and Windows release archives and ruff wheels are now code-signed. macOS executables are signed with an Apple Developer ID certificate and notarized by Apple. Windows executables have timestamped Authenticode signatures from Azure Artifact Signing. This enables verification of the release publisher and binary integrity, supports publisher-based allowlisting, and should reduce security warnings and antivirus false positives.

Breaking changes

  • Update the default and latest Python versions for 3.15 (#28792)

    Ruff now defaults to Python 3.11 instead of 3.10 when no Python version is configured through target-version or requires-python. When checking for syntax errors without a configured Python version, Ruff now defaults to Python 3.15

Looks like these dependencies are updatable in another way, so this is no longer needed.
