MCPs Installation

Who is this for? Teams that specifically need MCP: your IDE has no Rosetta plugin (Windsurf, Junie, OpenCode, or another MCP-compatible agent), or you need centrally-managed, always-fresh instructions with nothing copied into the repo. If your IDE supports Plugins, start there instead — most teams don’t need MCP. When should I read this? When you’ve decided MCP is the right fit and want to go from zero to a working setup.

[!CAUTION] You must receive prior approval from your manager and company to use it.

[!WARNING] Use Sonnet 5 medium, GPT-5.4-medium, gemini-3.1-pro or newer models. Avoid Auto model selection.

[!NOTE] Rosetta is designed to never use or see data or IP. Instead it uses inversion of control, by providing a “menu” to AI coding agents.

[!NOTE] The endpoint below (mcp.rosetta.griddynamics.net) is a public hosted instance for evaluation only — do not point production or sensitive repositories at it. Production use of MCP means deploying your own MCP server and RAGFlow inside your organization’s perimeter — see Deployment Guide.

Step 1: Connect Rosetta MCP

Rosetta uses HTTP MCP transport with OAuth.

  1. Pick your IDE and add the configuration.
  2. Authenticate to MCP using GitHub account according to IDE.
Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project):

{
  "mcpServers": {
    "Rosetta": {
      "url": "https://mcp.rosetta.griddynamics.net/mcp"
    }
  }
}
Claude Code 
claude mcp add --transport http Rosetta https://mcp.rosetta.griddynamics.net/mcp
Codex 
codex mcp add Rosetta --url https://mcp.rosetta.griddynamics.net/mcp
codex mcp login Rosetta
VS Code / GitHub Copilot

Add to .vscode/mcp.json or ~/.mcp.json:

{
  "servers": {
    "Rosetta": {
      "url": "https://mcp.rosetta.griddynamics.net/mcp"
    }
  }
}
GitHub Copilot (JetBrains)

Settings > Tools > GitHub Copilot > MCP Settings. Add to ~/.config/github-copilot/intellij/mcp.json:

{
  "servers": {
    "Rosetta": {
      "url": "https://mcp.rosetta.griddynamics.net/mcp"
    }
  }
}

Restart IDE after changes.

JetBrains Junie

Settings > Tools > Junie > MCP Settings > + Add > As JSON:

{
  "mcpServers": {
    "Rosetta": {
      "url": "https://mcp.rosetta.griddynamics.net/mcp"
    }
  }
}
Windsurf

Add to your Windsurf MCP config:

{
  "mcpServers": {
    "Rosetta": {
      "url": "https://mcp.rosetta.griddynamics.net/mcp"
    }
  }
}
Antigravity

Add to your Antigravity MCP config:

{
  "mcpServers": {
    "Rosetta": {
      "serverUrl": "https://mcp.rosetta.griddynamics.net/mcp"
    }
  }
}
OpenCode

Add to opencode.json:

{
  "mcp": {
    "Rosetta": {
      "type": "http",
      "url": "https://mcp.rosetta.griddynamics.net/mcp",
      "enabled": true
    }
  }
}

Step 2: Add Bootstrap Rule

Download mcp-files-mode.md and add it to your IDE’s instruction file (keep entire contents, including YAML frontmatter):

IDE Destination
Cursor .cursor/rules/mcp-files-mode.mdc
Claude Code .claude/claude.md
VS Code / GitHub Copilot .github/copilot-instructions.md
GitHub Copilot (JetBrains) .github/copilot-instructions.md
JetBrains Junie .junie/guidelines.md
Windsurf .windsurf/rules/mcp-files-mode.md
Antigravity .agents/rules/mcp-files-mode.md
OpenCode/Cursor AGENTS.md

Step 3: Verify

Ask the agent:

What can you do, Rosetta?

It should use Rosetta MCP to retrieve agents, guardrails, and instructions:

Rosetta proper response Rosetta proper response
