Affects both company and person notes formatters ## [0.2.0] - 2025-08-04 This is a major release featuring the Universal Tool Consolidation, which dramatically simplifies the MCP interface by replacing 50+ resource-specific tools with a unified set of universal tools that work across all resource types. ### Added #### Universal Tool System (#352, #358) - **Universal Tools**: New consolidated tools that work across all resource types (companies, people, deals, tasks, records) - `search-records`: Search any resource type with consistent interface - `get-record-details`: Get details for any record type - `create-record`: Create records of any type - `update-record`: Update records of any type - `delete-record`: Delete records of any type - `discover-attributes`: Discover attributes for any resource type - `get-detailed-info`: Get categorized information (basic, contact, business, social) - **Advanced Operations**: New tools for complex operations - `advanced-search`: Multi-attribute search with complex filters - `search-by-relationship`: Find records by their relationships - `search-by-content`: Search by notes or interaction content - `search-by-timeframe`: Search by creation/update dates - `batch-operations`: Perform bulk operations efficiently - **Resource Type Support**: Full support for companies, people, deals, tasks, and generic records - **Backwards Compatibility**: All existing tool names continue to work via intelligent routing #### Enhanced Error Handling System (#362) - Comprehensive error categorization (USER_ERROR, SYSTEM_ERROR, API_ERROR) - Detailed error messages with examples and suggestions - Field-specific guidance for common mistakes - HTTP status code mapping for better API integration - Structured error responses with actionable feedback #### Deal Management Improvements - Comprehensive deal field error messages for common mistakes (description, probability, source, close_date, tags, etc.) - Deal field documentation showing available vs non-existent fields - Currency handling guidance - Attio automatically formats currency based on workspace settings - Field name conversions for backwards compatibility: - `company_id` → `associated_company` - `deal_stage` → `stage` - `deal_value` → `value` - `deal_name` → `name` #### Documentation & Testing (#360, #359) - Complete universal tools documentation with examples - Comprehensive integration test suite for all universal operations - Performance benchmarks for batch operations - Migration guide from resource-specific to universal tools #### Developer Experience - Config migration tool for postal code mapping fix (#330) - Enhanced validation pipeline with mandatory pre-commit checks - Systematic lint reduction plan (targeting <100 warnings from ~800) - Improved environment setup for API integration testing ### Changed #### API & Tool Behavior - **Simplified Currency Handling**: Deal values now accept plain numbers (e.g., `value: 9780`) instead of complex objects - **Consistent Search Interface**: All search operations now use the same filter structure - **Unified Response Format**: All tools return consistent response structures - **Better Field Validation**: Proactive validation with helpful suggestions before API calls - **Improved Error Messages**: Context-aware error messages that guide users to solutions #### Infrastructure & Performance - Consolidated 50+ individual tool handlers into modular universal handlers - Reduced code duplication by ~70% through shared implementations - Improved response times through optimized routing - Better memory usage with streamlined tool definitions - Enhanced TypeScript type safety throughout the codebase ### Fixed #### Critical Fixes - Fixed deal currency format errors by accepting simple numeric values (#352) - Fixed company domain search regression - now correctly uses `domains` field instead of `website` (#334, #353) - Fixed "Format Error: An invalid value was passed to attribute with slug 'value'" issue - Fixed missing generic record operation handlers (#343, #349) - Fixed people search phone field regression (P0 hotfix) - Fixed list filtering for list-specific attributes (#341) #### Search & Filter Fixes - Fixed date filter operators to match Attio API requirements - Fixed domain search implementation by removing over-engineering - Fixed company search validation and enhanced error handling - Fixed filter condition type enum values for API compatibility #### API Integration Fixes - Fixed MCP tool calls failing with missing arguments wrapper (#344, #345) - Fixed relationship helper tools and type conversion issues (#347) - Fixed note formatting and content extraction (#338, #347) - Fixed schema alignment for add-record-to-list tool (#332) #### Testing & CI/CD Fixes - Fixed integration test failures with proper mock management - Fixed CI test compatibility with simplified mocks - Fixed flaky date tests for Node v22.x - Fixed TypeScript type issues and unnecessary try/catch warnings ### Security - Updated form-data dependency from 4.0.1 to 4.0.4 for security patches (#346) ### Deprecated - Resource-specific tool names (e.g., `search-companies`, `create-person`) are deprecated but still functional - Legacy field names for deals are deprecated but automatically converted - Individual resource type handlers are deprecated in favor of universal handlers ### Migration Guide Users upgrading from v0.1.x should note: 1. All existing tools continue to work - no breaking changes 2. Consider migrating to universal tools for new implementations 3. Deal currency values should now be simple numbers 4. Use `associated_company` instead of `company_id` for deals 5.
