Fixes include: 1. Add types-PyYAML to the dev dependencies for YAML type stubs 2. Initialize global variables in server.py properly 3. Fix missing return type annotations 4. Handle 'stream' attribute check more safely in CLI and main 5. Fix FastMCP stdio mode usage with environment variables 6. Create safe file copy helper function 7. Handle nullable types more safely in KubectlResult and KubectlError 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .github/workflows/pr-checks.yaml | 3 ++ pyproject.toml | 1 + src/mcp_server_troubleshoot/__main__.py | 14 +++++++--- src/mcp_server_troubleshoot/bundle.py | 37 +++++++++++++++++++------ src/mcp_server_troubleshoot/cli.py | 13 +++++---- src/mcp_server_troubleshoot/config.py | 3 +- src/mcp_server_troubleshoot/kubectl.py | 15 +++++++--- src/mcp_server_troubleshoot/server.py | 13 ++++++--- 8 files changed, 73 insertions(+), 26 deletions(-) diff --git a/.github/workflows/pr-checks.yaml b/.github/workflows/pr-checks.yaml index d7d4c7f..5efe002 100644 --- a/.github/workflows/pr-checks.yaml +++ b/.github/workflows/pr-checks.yaml @@ -35,6 +35,9 @@ jobs: # Install development dependencies uv pip install -e ".[dev]" + + # Install additional type stubs for CI + uv pip install types-PyYAML -
