Optimized Memory MCP Server V2

# Enhanced MCP Server Specification ## Project Overview This document outlines the specifications for an enhanced Model Context Protocol (MCP) server designed specifically for use with Claude Desktop, focusing on Infrastructure as Code (IaC) memory persistence. The server uses SQLite for data storage and is intended for single-user deployment on a local machine. ## Core Requirements [⬜] ### Environment Setup [⬜] - [ ] Accept DATABASE_URL environment variable pointing to SQLite database file - [ ] Validate database file existence on startup - [ ] Handle common SQLite connection errors - [ ] Implement single-user local access model ### Base MCP Implementation [⬜] - [ ] FastMCP server initialization - [ ] Claude Desktop integration - [ ] Basic error handling - [ ] Resource cleanup ## Database Schema [⬜] ### Core Tables [⬜] #### Entities Table [⬜] - [ ] Primary key (UUID) - [ ] Entity name (unique identifier) - [ ] Entity type - [ ] Creation timestamp - [ ] Last modified timestamp - [ ] Source context hash #### Relationships Table [⬜] - [ ] Primary key (UUID) - [ ] Source entity reference - [ ] Target entity reference - [ ] Relationship type - [ ] Creation timestamp - [ ] Context metadata #### Observations Table [⬜] - [ ] Primary key (UUID) - [ ] Entity reference - [ ] Observation content - [ ] Creation timestamp - [ ] Source context - [ ] Confidence score ### IaC-Specific Tables [⬜] #### Provider Resources Table [⬜] - [ ] Primary key (UUID) - [ ] Provider name (aws, azure, etc.) - [ ] Resource type - [ ] Resource name - [ ] Documentation URL - [ ] Schema version - [ ] Last verified timestamp #### Resource Arguments Table [⬜] - [ ] Primary key (UUID) - [ ] Resource reference - [ ] Argument name - [ ] Argument type - [ ] Required status - [ ] Default value - [ ] Validation rules - [ ] Deprecated status #### Ansible Collections Table [⬜] - [ ] Primary key (UUID) - [ ] Collection name - [ ] Module name - [ ] Version information - [ ] Documentation URL - [ ] Last verified timestamp #### Module Parameters Table [⬜] - [ ] Primary key (UUID) - [ ] Module reference - [ ] Parameter name - [ ] Parameter type - [ ] Required status - [ ] Default value - [ ] Choices list - [ ] Version added ## API Design [⬜] ### Core Memory Functions [⬜] - [ ] Create/read/update/delete entities - [ ] Manage relationships - [ ] Handle observations - [ ] Retrieve context ### IaC-Specific Functions [⬜] #### Provider Resource Management [⬜] - [ ] Register new resources - [ ] Validate schema changes - [ ] Track versions - [ ] Monitor deprecation status #### Ansible Module Management [⬜] - [ ] Register modules - [ ] Validate parameters - [ ] Check version compatibility - [ ] Track collection updates ### Query Functions [⬜] - [ ] Implement full-text search - [ ] Check resource compatibility - [ ] Analyze version differences - [ ] Generate deprecation warnings ## Implementation Tasks [⬜] ### Database Implementation [⬜] - [ ] Create table schemas - [ ] Define indexes - [ ] Implement foreign key constraints - [ ] Verify data integrity rules ### API Implementation [⬜] - [ ] Define FastMCP routes - [ ] Create request/response models - [ ] Implement error handling - [ ] Format responses ### Integration Features [⬜] - [ ] Create Claude Desktop configuration template - [ ] Implement environment variable handling - [ ] Manage database connections - [ ] Handle resource cleanup ## Testing Requirements [⬜] ### Unit Tests [⬜] - [ ] Test database operations - [ ] Verify API endpoints - [ ] Validate query functions - [ ] Check schema validation ### Integration Tests [⬜] - [ ] Verify Claude Desktop compatibility - [ ] Test database persistence - [ ] Validate resource management - [ ] Handle error scenarios ## README.md Content [⬜] ### Documentation Sections [⬜] - [ ] Installation instructions - [ ] Configuration steps - [ ] API reference - [ ] Schema documentation - [ ] Usage examples - [ ] Error reference - [ ] Integration guide ## Performance Considerations [⬜] - [ ] Optimize SQLite queries - [ ] Implement efficient indexing - [ ] Monitor resource usage - [ ] Handle concurrent operations Note: This specification assumes manual creation of the SQLite database file using the sqlite3 command-line tool. The server will expect the database file to exist at the location specified by DATABASE_URL.
