Use DX MCP Tools for LWC (Beta)

Salesforce Developer Experience (DX) Model Context Protocol (MCP) tools for LWC provide a powerful set of capabilities for component and app development, enabling advanced code intelligence, context-aware suggestions, and seamless integration with Salesforce metadata. MCP tools help streamline the development workflow, improve productivity, and ensure your code follows best practices.

MCP Tools for LWC is a pilot or beta service that is subject to the Beta Services Terms at Agreements - Salesforce.com or a written Unified Pilot Agreement if executed by Customer, and applicable terms in the Product Terms Directory. Use of this pilot or beta service is at the Customer’s sole discretion.

Note

We recommend that you use the MCP tools through Agentforce Vibes Extension. Agentforce Vibes is pre-configured with the Salesforce DX MCP Server (Beta). This setup offers the most integrated and robust experience, including real-time code analysis, context-driven completions, and direct access to Salesforce data models.

For developers using other clients, such as Cursor or VS Code with Copilot, install the Salesforce DX MCP Server (Beta) to enable the LWC MCP tools.

Enable the Toolsets

When configuring the DX MCP server and the Agentforce Vibes extension, several MCP tools are enabled by default. To enable all the tools in these toolsets, pass in the toolset names (aura-experts, lwc-experts, and experts-validation) using the --toolsets flag. As some tools can call other tools in the toolset, enabling all toolsets is recommended if you expect to use these tools for LWC development.

1{
2  "mcpServers": {
3    "Salesforce DX": {
4      "command": "npx",
5      "args": [
6        "-y",
7        "@salesforce/mcp@latest",
8        "--orgs",
9        "DEFAULT_TARGET_ORG",
10        "--toolsets",
11        "lwc-experts,aura-experts,experts-validation"
12      ]
13    }
14  }
15}

To specify individual tools, use the --tools flag instead.

1{
2  "mcpServers": {
3    "Salesforce DX": {
4      "command": "npx",
5      "args": [
6        "-y",
7        "@salesforce/mcp@latest",
8        "--orgs",
9        "DEFAULT_TARGET_ORG",
10        "--tools",
11        "guide_figma_to_lwc_conversion,create_lwc_component_from_prd"
12      ]
13    }
14  }
15}

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

2  "mcpServers": {
3    "Salesforce DX": {
4      "command": "npx",
5      "args": [
6        "-y",
7        "@salesforce/mcp@latest",
8        "--orgs",
9        "DEFAULT_TARGET_ORG",
10        "--toolsets",
11        "lwc-experts, aura-experts, experts-validation",
12        "--allow-non-ga-tools"
13      ]
14    }
15  }
16}

For more information, see Install and Configure the Salesforce DX MCP Server (Beta) in the Salesforce DX Developer Guide.

When working with these tools using Agentforce Vibes Extension, you must enable the a4d-general-rules-no-edit.md and a4d-lwc-rules-no-edit.md global rules. The a4d-general-rules-no-edit.md rule is enabled by default. For more information on configuring rules in Agentforce Vibes, see Agentforce Rules in the Agentforce Vibes Extension Developer Guide.

Aura Toolset

The aura-experts toolset provides tools for Aura component analysis, blueprinting, and Aura-to-LWC migration expertise.

Aura-to-LWC Migration Tools

LWC Validation Toolset

The experts-validation toolset provides tools for validating and scoring LWC components for production readiness across accessibility, security, and other best practices.

Validation MCP Tools

For other available toolsets, see Salesforce DX MCP Server.

MCP Tools for LWC uses generative AI, which can produce inaccurate or harmful responses. The output generated by AI is often nondeterministic. Before using the generated output, review it for accuracy and safety. You assume responsibility for how the outcomes are applied to your organization.

LWC and Aura Toolsets Benefits

The LWC and Aura toolsets analyze your Aura components to understand:

Component structure and hierarchy
Event handling patterns
Data binding approaches
Custom interfaces and dependencies
Third-party integrations

Using these MCP tools, you can get a detailed migration plan including:

Dependency analysis and order of conversion
Risk assessment for complex components
Time estimates for each component
Compatibility considerations

With the orchestrated migration tool, you can generate modern LWC equivalents from existing Aura sources. Migrated components include:

Standard LWC component class structure
Template conversion with proper binding
CSS with LWC-specific optimizations
Jest test suites for the new components
