Scalix World — MCP Server

The official Model Context Protocol server for Scalix World, the AI-native neocloud. One hosted MCP server lets an agent operate the entire platform — no local install. Database, compute, functions, storage, auth, AI, DNS and billing: 50 tools across 17 domains, one API key.

Claude Code plugin (recommended)

Install the full package — 50 tools, 4 skills and a /scalix:setup command:

claude plugin marketplace add scalixworld/scalix-cloud-mcp
claude plugin install scalix@scalix

Then run /scalix:setup inside Claude Code to connect and verify.

Antigravity (Google)

Install as a plugin (recommended — one command):

git clone https://github.com/scalixworld/scalix-cloud-mcp ~/.gemini/config/plugins/scalix

Then open the plugin's mcp_config.json and replace YOUR_SCALIX_API_KEY with a key from scalix.world (Console → API Keys). Antigravity auto-discovers plugins in ~/.gemini/config/plugins/ (global) or .agents/plugins/ (per-workspace).

Or add the server directly: paste the mcpServers block from mcp_config.json into ~/.gemini/config/mcp_config.json (Antigravity 2.0 / IDE) — or in Antigravity CLI type /mcp for the interactive manager. Note Antigravity uses serverUrl (not url).

Gemini CLI

gemini extensions install https://github.com/scalixworld/scalix-cloud-mcp

Set SCALIX_API_KEY in your environment; the extension config and GEMINI.md context load automatically.

Connect

https://api.scalix.world/v1/mcp

Authenticate with a Scalix World API key (Authorization: Bearer <key>), scopable to specific services, projects, and actions. Listed in the official MCP registry as world.scalix/cloud.

Example (Claude Code):

claude mcp add --transport http scalix https://api.scalix.world/v1/mcp \
  --header "Authorization: Bearer $SCALIX_API_KEY"

What an agent can do with it

• Databases — provision Postgres-compatible databases with scale-to-zero; create copy-on-write branches to test migrations, then promote or drop them

• Compute — deploy container services and serverless functions in isolated microVMs

• Storage, Auth, DNS, Email — manage the production primitives around the app

• AI inference — run AI workloads with routing, metering, and spend controls

• Observability & billing — read logs and metrics, check usage and remaining credits; the agent can make cost-aware decisions with the same key it deploys with

Consequential actions (deletes, production changes, spend past budget caps) pause for human approval — guardrails are a platform feature, not a wrapper script.

About

Scalix World is a fully managed cloud platform engineered as one system — database, AI, compute, storage, auth, billing — operable by humans through a console and by agents through this MCP server, on sovereign European infrastructure. Built by Scalix.
