- Lists all custom modes in the .roomodes file.
- Creates new custom modes with slug, name, roleDefinition, customInstructions, and groups.
- Retrieves the full fields of a specific custom mode.
- Updates one or more fields of a custom mode without rewriting the entire file.

Setting up with Highlight

This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:

  1. Download and install Highlight from highlightai.com/download
  2. Navigate to the plugins tab and select "Add Custom Plugin"
  3. Configure the plugin with the settings below
    Plugin Name roo-code-custom-mode-editor-mcp-server
    Command (node, npx, python, etc.)

    Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.

  4. Enable "Start Automatically" if you want the plugin to start when Highlight launches

From the repository

Run the server with npx https://github.com/raymondlowe/roo-code-custom-mode-editor-mcp-server. To integrate with Roo Code, add a server configuration entry to the MCP settings file pointing to the built index.js (the server has a build step via npm run build). The server communicates over stdio and exposes four tools: list_custom_modes, create_custom_mode, get_custom_mode_fields, and put_custom_mode_fields.

# roo-code-custom-mode-editor-mcp-server An MCP server that knows how to edit the Roo Code custom modes file Avoids having to overwrite the `.roomodes` file using file writes or edit the json with unreliable diffs. The MCP server exposes tools to: * List all custom modes * Create a new custom mode * Get the fields of a custom mode ( "slug","name", "roleDefinition", "customInstructions", "groups") * Put and overwrite any one or more fields of a custom mode. Fields are: - slug : short string - name : short string - roleDefinition : long string - customInstructions : long string - groups : array of short strings ## Usage This server is located at https://github.com/raymondlowe/roo-code-custom-mode-editor-mcp-server and can be run using the following command: ```bash npx https://github.com/raymondlowe/roo-code-custom-mode-editor-mcp-server ``` ## MCP Configuration To use with Roo Code, add the server config to the MCP settings file: ```json { "mcpServers": { "roo-code-custom-mode-editor": { "command": "node", "args": [ "/path/to/roo-code-custom-mode-editor-mcp-server/build/index.js" ], "disabled": false, "alwaysAllow": [] } } } ``` ## Development Install dependencies: ```bash npm install ``` Build the server: ```bash npm run build ``` For development with auto-rebuild: ```bash npm run watch ``` ### Debugging Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector), which is available as a package script: ```bash npm run inspector ``` The Inspector will provide a URL to access debugging tools in your browser. ## Tools ### list_custom_modes Lists all custom modes in the `.roomodes` file. ### create_custom_mode Creates a new custom mode with the specified fields. Parameters: - slug: string - name: string - roleDefinition: string - customInstructions: string - groups: string[] ### get_custom_mode_fields Gets the fields of a custom mode. Parameters: - slug: string ### put_custom_mode_fields Updates one or more fields of a custom mode. Parameters: - slug: string - fields: object containing any of the following fields: - name: string - roleDefinition: string - customInstructions: string - groups: string[]
