Roo Code Mode Editor

Example Use Cases

• 1

  List all custom Roo Code modes and their slugs without parsing the .roomodes file directly

• 2

  Create new custom modes programmatically with fields like slug, name, roleDefinition, customInstructions, and groups

• 3

  Retrieve or update one or more fields of an existing custom mode atomically to avoid corrupting the .roomodes file

Description

This MCP server exposes commands to list custom modes, create new modes, retrieve a mode's fields, and update one or more fields of an existing mode in the .roomodes file. It avoids directly overwriting the file with ad-hoc file writes or brittle JSON diffs by providing structured operations over the MCP protocol. The server is easy to run locally via npx and can be integrated into Roo Code by adding its config to the MCP settings.
