This commit upgrades the entire codebase to Rust 1.88 and edition 2024 to take advantage of the latest language features and improvements. Changes include: - Update rust-toolchain.toml to specify Rust 1.88 with required components - Update workspace Cargo.toml to set rust-version = "1.88" and edition = "2024" - Fix unsafe set_var calls in mcp-auth by adding proper unsafe blocks with safety comments - Update pattern matching syntax to comply with edition 2024 requirements - Remove unnecessary 'ref' binding modifiers that are no longer allowed The migration enables access to edition 2024 features while maintaining backward compatibility and ensuring all code adheres to the latest Rust idioms and safety requirements.
Updates all GitHub Actions workflows to support the new Rust toolchain and resolves CI reliability issues. Changes include: - Update all workflows to use Rust 1.88 toolchain consistently - Increase External Validation timeout from 30 to 45 minutes to prevent macOS and Windows job failures due to insufficient time allocation - Improve cache keys to include Rust version and toolchain file hashes for better cache invalidation when toolchain changes - Remove invalid --timeout parameter from cargo test commands that was causing CI failures These changes address the recurring CI timeout and failure issues that were blocking successful builds on platform-specific runners.
Adds comprehensive support for MCP resources and prompts through new
procedural macros that automatically generate protocol handlers.
New macros:
- #[mcp_resource] - Generates resource handlers with URI template parsing,
parameter extraction, and automatic content type handling
- #[mcp_prompt] - Generates prompt handlers with argument validation and
message generation
Key features:
- URI template parsing with {param} placeholder support
- Type-safe parameter extraction from URI paths
- Automatic schema generation for prompt arguments
- Integration with existing server capability detection
- Support for both sync and async resource/prompt functions
- Comprehensive error handling with protocol error conversion
- Auto-documentation from function doc comments
These macros enable developers to define MCP resources and prompts using
simple function annotations, dramatically reducing boilerplate while
maintaining full protocol compliance and type safety.
Enhances the macro system to automatically detect and enable MCP capabilities when resources and prompts are defined. Changes include: - Update mcp_backend and mcp_server macros to enable resources and prompts capabilities by default, providing seamless integration - Add integration hooks for automatic discovery of resources and prompts defined with the new macros - Implement default handler methods that route requests to macro-generated functions when available - Add comprehensive documentation for new macro attributes and parameters - Enhance utility functions to support resource and prompt parameter parsing The auto-detection system ensures that servers automatically advertise their capabilities correctly, eliminating manual configuration while maintaining backward compatibility with existing implementations. Resource and prompt handlers are now automatically registered and discoverable by MCP clients without additional setup.
Implements extensive test coverage for the new MCP resource and prompt macros, along with enhanced backend and server lifecycle testing. New test files: - mcp_resource_tests.rs - Tests for resource URI templates, parameter extraction, MIME type handling, and error conditions - mcp_prompt_tests.rs - Tests for prompt argument validation, message generation, and template processing - backend_integration_tests.rs - Tests for backend macro with struct/enum support and capability auto-detection - server_lifecycle_tests.rs - Tests for server creation, configuration, and fluent API patterns - error_handling_tests.rs - Comprehensive error handling tests across all macro types with custom error types These tests ensure reliability and correctness of the new macro system, covering edge cases, error conditions, and integration scenarios. The test suite validates that generated code properly handles both sync and async functions, complex parameter types, and protocol compliance.
Expands test coverage with sophisticated validation for macro attributes, async/sync patterns, parameter handling, and documentation extraction. New test files: - macro_attribute_tests.rs - Tests for all macro attribute combinations, custom configurations, and documentation inheritance patterns - async_sync_tests.rs - Tests for mixed async/sync function handling, concurrent execution, and performance characteristics - parameter_validation_tests.rs - Tests for complex parameter types, edge cases, validation rules, and error handling - documentation_tests.rs - Tests for doc comment extraction, formatting, and integration with generated code These tests validate advanced macro functionality including: - Complex type system integration with custom structs and enums - Unicode and special character handling in parameters - Concurrent access patterns and thread safety - Documentation preservation and formatting across all macro types - Validation of edge cases and error conditions The expanded test suite ensures robust handling of real-world usage patterns and provides confidence in the macro system's reliability.
Completes the comprehensive test suite with specialized tests for performance, security, complex type systems, and full integration scenarios. New test files: - performance_tests.rs - Performance and concurrency tests with metrics for CPU-intensive, I/O-intensive, and memory-intensive operations - security_tests.rs - Security-focused tests with input sanitization, validation, access control, and attack prevention measures - type_system_tests.rs - Complex type system integration tests with custom types, generics, serialization, and error handling - integration_full_tests.rs - Full integration tests combining all macro features in realistic server scenarios Key testing areas: - Performance benchmarking and concurrent access patterns - Security validation including injection prevention and rate limiting - Complex data structures with custom serialization/deserialization - End-to-end integration with all macros working together - Real-world usage patterns and edge case handling This completes the expansion from 9 to 21 test files, providing comprehensive coverage of all macro functionality and ensuring production-ready reliability and security.
Excludes local Claude configuration files from version control as they contain development-specific settings that should not be shared across different development environments.

…t code This commit addresses Rust edition 2024 compatibility by wrapping all std::env::set_var and std::env::remove_var calls in test code with proper unsafe blocks and safety comments. In Rust edition 2024, environment variable modification functions are marked as unsafe due to potential data races when multiple threads access environment variables concurrently. This change ensures all test code complies with the new safety requirements. Changes: - Add unsafe blocks around all env::set_var/remove_var calls in tests - Include safety comments explaining the context (test environment setup) - Maintain existing test functionality while meeting edition 2024 requirements Files affected: - mcp-auth/src/storage.rs: Storage backend tests - mcp-auth/src/transport/stdio_auth.rs: Authentication extraction tests - mcp-auth/tests/vault_integration_tests.rs: Vault integration tests - mcp-cli-derive/tests/test_mcp_config.rs: Configuration derivation tests - mcp-cli/src/config_tests.rs: CLI configuration tests This resolves clippy errors about unsafe function calls and ensures compatibility with Rust 1.88 edition 2024 requirements.
This commit addresses various clippy warnings in the MCP resource and prompt macro implementation to improve code quality and follow Rust best practices. Changes: - Replace format\! with string interpolation for better performance - Remove unnecessary as_ref().map(|d| d.clone()) pattern - Convert while let loop to for loop for better iterator handling - Use direct string interpolation in format\! macros Specific fixes: - mcp_prompt.rs: Fix uninlined_format_args and useless_asref warnings - mcp_resource.rs: Fix uninlined_format_args, while_let_on_iterator, and useless_asref warnings These changes maintain the same functionality while following modern Rust idioms and eliminating clippy warnings when building with -D warnings flag.
This commit improves test isolation by replacing generic app names and hardcoded paths with unique, test-specific identifiers. This prevents conflicts when running multiple MCP applications or tests concurrently. Changes to test app names: - Macro tests now use descriptive suffixes (e.g., "test-app-macro-attribute-tests") - Security tests use "security-test-security-tests" - Lifecycle tests use "lifecycle-test-app-server-lifecycle-tests" - Each test module has a unique app_name to avoid auth storage conflicts Changes to test paths: - Replace hardcoded /tmp paths with temp_dir() based paths - Use test-specific directory names for better isolation - Add UUID generation for auth test storage paths - Update logging, auth config, and vault tests to use unique directories Benefits: - Prevents test interference when running parallel test suites - Eliminates race conditions in shared storage locations - Enables safe concurrent execution of multiple MCP instances - Improves test reliability and debugging capabilities Files updated: - mcp-macros/tests/: Updated all test servers with unique app names - mcp-auth/src/: Updated storage paths in config and vault tests - mcp-cli/src/: Updated logging configuration test paths - mcp-logging/src/: Updated metrics persistence test paths - mcp-auth/tests/: Enhanced test utilities with UUID-based paths This addresses the test isolation issues identified in the application- specific storage path requirements and ensures each test runs in its own isolated environment.
