Scalix Cloud
The agent-native cloud: database, functions, AI, storage, computers. 51 tools, one API key.
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
claude mcp add --transport http scalix-cloud 'https://api.scalix.world/v1/mcp' --header 'Authorization: <Bearer <your Scalix API key> - create one free at https://console.scalix.world>'
{
"mcpServers": {
"scalix-cloud": {
"type": "http",
"url": "https://api.scalix.world/v1/mcp",
"headers": {
"Authorization": "<Bearer <your Scalix API key> - create one free at https://console.scalix.world>"
}

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: 51 tools across 17 domains, one API key.
Claude Code plugin (recommended)
Install the full package — 51 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.
