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

{
"mcpServers": {

}
}
}
Development

Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:
npm run inspector
The Inspector will provide a URL to access debugging tools in your browser.
