MCPs Installation

Who is this for? New users setting up Rosetta for the first time. When should I read this? When you want to go from zero to a working setup.

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

[!WARNING] Use Sonnet 4.6, GPT-5.4-medium, gemini-3.1-pro or better 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.

Step 1: Connect Rosetta MCP

Rosetta uses HTTP MCP transport with OAuth.

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.

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
    }
  }
}

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

IDE	Destination
Cursor	`.cursor/rules/bootstrap.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/bootstrap.md`
Antigravity	`.agent/rules/bootstrap.md`
OpenCode/Cursor	`AGENTS.md`

Ask the agent:

What can you do, Rosetta?

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

Rosetta proper response

OAuth prompt does not appear: restart your IDE and retry the connection. Read more in Troubleshooting — Connection & Authentication.
Agent ignores Rosetta tools: confirm the MCP server shows as connected in your IDE’s MCP settings. Add a bootstrap rule if the agent still skips Rosetta. Read more in Troubleshooting — Agent Not Using Rosetta.
Slow or empty responses: check your network can reach your Rosetta MCP host. See TROUBLESHOOTING.md.

Once the MCP is verified:

Run your first session and initialize the repo — see QUICKSTART.md.
Explore the workflows (coding, requirements authoring, modernization, and more) — see USAGE_GUIDE.md — Workflows.
