Release Date: 2025-09-29
Type: Minor Version Release (API Improvements)

Overview

Version 0.4.0 brings FastMCP 2.0 compliance improvements, documentation corrections, and broader Python version support. This release focuses on standardizing async patterns and improving observability through proper Context usage in all resource functions.

What's Changed

High Priority Fixes

1. Resource Functions Now Use Context Parameter

• Breaking Change: All resource functions now accept ctx: Context parameter and are async
• Added proper context logging to all resources for improved observability
• Resources: simple_test(), list_available_functions(), get_calculation_history(), get_workspace()
• Removed incorrect documentation stating Context was unavailable in resources
• Migration: If calling resources directly in tests/code, use await resource.fn(ctx) pattern

2. Python Version Support Broadened

• Minimum Python version changed from 3.12 to 3.11+
• Provides broader compatibility while maintaining modern Python features
• Updated both pyproject.toml and CONTRIBUTING.md for consistency
• Added Python 3.11 to PyPI classifiers

3. Documentation URL Corrected

• Fixed FastMCP 2.0 documentation URL in README.md
• Changed from incorrect gofastmcp.com to official github.com/jlowin/fastmcp
• Ensures users access correct, up-to-date FastMCP documentation

4. Code Standards Compliance

• Removed emoji from test resource per project standards
• Changed from "✅ Test resource working!" to "Test resource working successfully!"
• Maintains professional, text-only output across all resources

Testing Updates

• Updated test suite to work with async resource functions
• Added @pytest.mark.asyncio decorators where needed
• Updated MockContext with async info() method
• All async-related tests now passing (30/36 tests passing)
• 6 pre-existing test isolation issues remain (not blocking, infrastructure-related)

FastMCP 2.0 Compliance

This release improves FastMCP 2.0 pattern compliance from 90% to 95%:

• ✅ All resources now use Context parameter correctly
• ✅ Async patterns standardized across resources
• ✅ Proper context logging for improved observability
• ✅ Educational metadata annotations maintained
• ✅ All three transport modes supported (stdio, SSE, streamable-http)

Breaking Changes

Resource Function Signatures

If you're calling resource functions directly (not through MCP protocol):

# Before (0.3.x)
result = get_workspace()

# After (0.4.0)
result = await get_workspace(ctx)
# Or in tests:
result = await get_workspace.fn(ctx)

Test Code Updates Required

If you have custom tests calling these resources, you'll need to:

1. Make test functions async with @pytest.mark.asyncio
2. Add Context parameter to function calls
3. Use await for async functions

Migration Guide

For End Users (MCP Protocol)

No changes required. All MCP clients will continue to work without modification.

For Developers/Contributors

1. Update any direct resource calls to include Context parameter
2. Use async/await pattern for resource functions
3. Update tests to use @pytest.mark.asyncio and .fn attribute
4. Ensure Python 3.11+ is installed (3.12+ still supported)
