The experts-validation toolset is new. Use this toolset to validate and score LWC components for production readiness across accessibility, security, and best practices. The experts-validation toolset provides these MCP tools.

  • validate_and_optimize—Validates code quality by running the Code Analyzer, Data, LWC best practices, Security, and Accessibility validators.
  • score_issues—Consumes the validator findings to compute an overall readiness score from 0 to 100 and assigns a quality grade, such as review-for-production, prototype, or draft.

experts-validation is also available for React apps in Salesforce Multi-Framework.

These tools have changes:

  • The orchestrate_lwc_slds2_uplift (NON-GA) tool now analyzes LWC code along with SLDS Linter output to fix issues using SLDS 2 knowledge, and provides migration guidance for upgrading to SLDS 2.
  • The explore_lds_graphql_schema and guide_lwc_slds2_uplift_linter_fixes tools have been removed.
  • The guide_lwc_security tool has been renamed as guide_lws_security.
  • The 
    guide_lwc_accessibility
    tool has been renamed as guide_component_accessibility.

Note

Some tools are not yet generally available (NON-GA). To use NON-GA tools, specify the --allow-non-ga-tools flag in your DX MCP Server configuration.

We recommend that you use the LWC MCP tools via Agentforce Vibes Extension. Agentforce Vibes is pre-configured with the Salesforce DX MCP Server (Beta). To enable the LWC MCP tools using other clients, such as Cursor or VS Code with Copilot, install the Salesforce DX MCP Server (Beta).
