Added DISABLED_TOOLS environment variable to filter specific tools from registration at startup, enabling deployment-specific tool configuration for multi-tenant deployments, security hardening, and feature flags. ## Implementation - Added getDisabledTools() method to parse comma-separated tool names from env var - Modified ListToolsRequestSchema handler to filter both documentation and management tools - Modified CallToolRequestSchema handler to reject disabled tool calls with clear error messages - Added defense-in-depth guard in executeTool() method ## Features - Environment variable format: DISABLED_TOOLS=tool1,tool2,tool3 - O(1) lookup performance using Set data structure - Clear error messages with TOOL_DISABLED code - Backward compatible (no DISABLED_TOOLS = all tools enabled) - Comprehensive logging for observability ## Use Cases - Multi-tenant: Hide tools that check global env vars - Security: Disable management tools in production - Feature flags: Gradually roll out new tools - Deployment-specific: Different tool sets for cloud vs self-hosted ## Testing - 45 comprehensive tests (all passing) - 95% feature code coverage - Unit tests + additional test scenarios - Performance tested with 1000 tools (<100ms) ## Files Modified - src/mcp/server.ts - Core implementation (~40 lines) - .env.example, .env.docker - Configuration documentation - tests/unit/mcp/disabled-tools*.test.ts - Comprehensive tests - package.json, package.runtime.json - Version bump to 2.22.14 - CHANGELOG.md - Full documentation Resolves #410 Conceived by Romuald Członkowski - www.aiadvisors.pl/en
