chore(deps): bump python-dotenv from 1.1.1 to 1.2.2

[dependabot]

Bumps python-dotenv from 1.1.1 to 1.2.2.

Release notes

Sourced from python-dotenv's releases.

v1.2.2

Added

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

Changed

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

Fixed

• Improved set_key and unset_key behavior when interacting with symlinks by @​bbc2 in #790c5
• Corrected the license specifier and added missing Python 3.14 classifiers in package metadata by @​JYOuyang in theskumar/python-dotenv#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.

Misc

• skip 000 permission tests for root user by @​burnout-projects in theskumar/python-dotenv#561
• Bump actions/checkout from 5 to 6 in the github-actions group by @​dependabot[bot] in theskumar/python-dotenv#593
• Add Windows testing to CI by @​bbc2 in theskumar/python-dotenv#604
• Improve workflow efficiency with best practices by @​theskumar in theskumar/python-dotenv#609
• Remove the use of sh in tests by @​bbc2 in theskumar/python-dotenv#612

New Contributors

• @​JYOuyang made their first contribution in theskumar/python-dotenv#590
• @​burnout-projects made their first contribution in theskumar/python-dotenv#561
• @​cpackham-atlnz made their first contribution in theskumar/python-dotenv#597

[claude]

LGTM — routine dependabot lockfile bump of python-dotenv 1.1.1 → 1.2.2.

What was reviewed:

• uv.lock is the only changed file; the pyproject.toml constraint (python-dotenv>=1.0.0, cli extra) is unchanged and satisfied by 1.2.2.
• Checked the upstream breaking changes (set_key/unset_key symlink and file-mode behavior) against SDK usage — the SDK only calls dotenv.dotenv_values() in src/mcp/cli/cli.py, so it is unaffected.
• Upstream dropped Python 3.9, which is below this SDK's 3.10 floor, so the supported-version matrix is unaffected.

Extended reasoning...

Overview

Dependabot PR bumping python-dotenv from 1.1.1 to 1.2.2 in uv.lock only. No source code, dependency constraints, or CI configuration are modified. python-dotenv is an optional dependency of the cli extra with a >=1.0.0 floor, which 1.2.2 satisfies.

Security risks

None introduced by the SDK side of this change. The new upstream release actually tightens security posture (symlinks are no longer followed by set_key/unset_key by default). The sdist/wheel hashes in the lockfile pin the exact artifacts, so there is no supply-chain ambiguity beyond trusting PyPI's published release.

Level of scrutiny

Low. This is a mechanical lockfile update with no code changes. The main thing worth verifying was whether the upstream breaking changes affect the SDK: they are confined to set_key/unset_key and the dotenv CLI, while the SDK only uses dotenv.dotenv_values() (read-only) in src/mcp/cli/cli.py. The upstream drop of Python 3.9 support is also irrelevant since this SDK requires Python 3.10+.

Other factors

The bug hunting system found no issues, and there are no reviewer comments or prior reviews on the timeline. CI runs the full test matrix (3.10–3.14 across platforms) against the locked versions, which exercises the CLI import path. This fits squarely in the approve category: simple, mechanical, self-contained.
