studio

TL;DR: Your team needs a secure internal vibecoding platform. You just found it. Configure agents with team context. Connect private MCPs once — share capabilities, not credentials. Keep the model layer interchangeable. Roll out across the organization with SSO, RBAC, audit logs, and cost controls — all through one MCP endpoint. Local-first. Self-host or use the cloud.

What is deco Studio?

Studio packages the infrastructure behind an internal AI rollout: model routing, MCP authentication, agent configuration, SSO, RBAC, audit logs, and usage accounting. Your teams get chat. You keep control.

Under the hood it's one control plane for your AI agents — one MCP endpoint for all your agents, tools, and models. Agents package context, tools, and policy into something you publish to the organization. Connections give them governed access to your systems — GitHub, Slack, Postgres, Sentry, anything that speaks MCP — with tokens stored in an encrypted vault. Models stay interchangeable: OpenRouter or direct providers, chosen per agent and per tool.

Start with one team. Standardize approved models, tools, and context. Expand across the organization without copying secrets or rebuilding the platform. Install locally and it stays private; sync to the cloud for remote access, team roles, and shared billing.

Quick Start

Install Docker with Compose, then run from source:

git clone https://github.com/decocms/studio.git
cd studio
docker compose up --build --watch

Open http://localhost:4000. Compose starts PostgreSQL, NATS, object storage, migrations, and the hot-reloading API and web app. See CONTRIBUTING.md for contributor setup and worktrees.

What you get

Agents

Package context, tools, and policy into an agent. Define instructions, add skills and files, grant approved MCP access, choose a model policy, then publish the agent to the organization. Each agent is its own MCP endpoint — callable from Cursor, Claude Desktop, your own code, or another agent. Agents compose, and every action is tracked with cost attribution.

Connections

Connect private systems once, securely. Register MCP servers at the organization level through a web UI with one-click OAuth — no JSON configs. Tokens live in the encrypted vault, and you grant tool-level access by organization, role, or agent. Share MCP capabilities — not credentials.

As tool surfaces grow, Studio exposes Virtual MCPs — one endpoint, different strategies for which tools to surface:

• Full-context: expose everything (simple, deterministic, good for small toolsets)
• Smart selection: narrow the toolset before execution
• Code execution: load tools on demand in a sandbox

Models

Keep the AI layer interchangeable. Use OpenRouter or connect Anthropic, OpenAI, Google, or any compatible provider directly — the best model for each agent and tool, behind one router. For coding work, engineers can link their own Claude Code or Codex session and use the subscription already authenticated on their machine.

Projects

Projects bring agents and connections together around a goal. The project's UI adapts to what's inside — add a content agent and a CMS connection, the sidebar shows content management; add an analytics agent and a database, it shows dashboards and queries. The UI you see is the UI that's relevant for operating that project.

Observability

Account for every model and tool call. Trace the user, agent, model, tools, latency, errors, tokens, and cost for every thread. Break usage down by agent, connection, organization, or teammate — one dashboard.

From your desktop to your org

Core Capabilities

Define Tools

Type-safe, audited, observable, callable via MCP.

import { z } from "zod";
import { defineTool } from "~/core/define-tool";

export const CONNECTION_CREATE = defineTool({
  name: "CONNECTION_CREATE",
  description: "Create a new MCP connection",
  inputSchema: z.object({
    name: z.string(),
    connection: z.object({
      type: z.enum(["HTTP", "SSE", "WebSocket"]),
      url: z.string().url(),
      token: z.string().optional(),
    }),
  }),
  outputSchema: z.object({
    id: z.string(),
    scope: z.enum(["workspace", "project"]),
  }),
  handler: async (input, ctx) => {
    await ctx.access.check();
    const conn = await ctx.storage.connections.create({
      projectId: ctx.project?.id ?? null,
      ...input,
      createdById: ctx.auth.user!.id,
    });
    return { id: conn.id, scope: conn.projectId ? "project" : "workspace" };
  },
});

Every tool call gets input/output validation, access control, audit logging, and OpenTelemetry traces automatically.

Documentation

Studio documentation lives in docs-tanstack, alongside the Storefront documentation. Update public product guides and architecture there. Workspace READMEs and engineering plans stay here with the implementation.
