Consulting control plane for AI coding agents

What is Rosetta

Rosetta is a consulting control plane for AI coding agents. It consults them with versioned, expert-prepared instructions so every agent follows your organization’s rules, conventions, and knowledge. Works across IDEs, runs locally, and keeps instructions versioned as code.

Every AI interaction follows four phases: Prepare (load guardrails and context), Research (search the knowledge base), Plan (produce a reviewable plan), Act (execute with full context). Read more in the Usage Guide.

Why use it

• Context engineering, not prompt hacking. Agents receive your conventions, architecture, and business rules automatically — structured, versioned, and ready before the first line of code. See how it fits your workflow.
• Write once, run everywhere. Agent-agnostic design adapts to any IDE and any tech stack. No per-tool maintenance.
• Guardrails built in. Approval gates, risk assessment, and data protection ensure consistent AI behavior across teams. See how Rosetta protects you.
• Cross-project intelligence. Publish business and technical context from every project into a shared knowledge base. Agents see the system, not just one repo — trace flows across services, catch breaking API changes before they ship, and assess blast radius of any change across the portfolio.
• One-command onboarding. New repo, new developer — productive immediately with best practices baked in.
• Instructions as code. Prompts version-controlled with release management — single source of truth for all teams.

How it works

Your IDE connects to the Rosetta MCP server. The server transforms, bundles, and contextualizes knowledge from workflows, guardrails, coding conventions, and project context. The coding agent receives structured instructions from Rosetta and applies them to your code.

Rosetta never sees your source code. It only serves knowledge and instructions to the agent. The agent loads only what it needs per request (progressive disclosure) and follows your organization’s workflows.

Get Started

Cursor — add to ~/.cursor/mcp.json or .cursor/mcp.json:

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

Claude Code:

claude mcp add --transport http Rosetta https://rosetta.evergreen.gcp.griddynamics.net/mcp

Codex:

codex mcp add Rosetta --url https://rosetta.evergreen.gcp.griddynamics.net/mcp
codex mcp login Rosetta

Complete the OAuth flow when prompted. Then ask: “Initialize this repository using Rosetta”
