Installation

Plugins

We ship plugins that bundle the api-gateway skill for popular agent harnesses.

Claude Code — add this repo as a plugin marketplace, then install the plugin:

claude plugin marketplace add maton-ai/api-gateway-skill
claude plugin install api-gateway@maton-plugins

Cursor — install the plugin directly from this repo:

/add-plugin maton-ai/api-gateway-skill

Codex — add this repo as a plugin marketplace, then install the plugin:

codex plugin marketplace add maton-ai/api-gateway-skill
codex plugin add api-gateway@maton-plugins

Kiro — shipped as a Power. Kiro has no install CLI; import it from GitHub inside the IDE:

Open the Powers panel (the Ghosty icon with the lightning bolt).
Choose Add Custom Power → Import power from GitHub.
Paste the power folder URL: https://github.com/maton-ai/api-gateway-skill/tree/main/providers/kiro/.kiro/powers/api-gateway
Click Install. Kiro reads POWER.md (and its local references/) and activates the power on demand when your request matches its keywords.

ClawHub — install using the clawhub CLI:

clawhub install @byungkyu/api-gateway

Network Access

The skill requires outbound network access to maton.ai.

Claude Desktop / Claude Cowork

Free / Pro / Max plans

Package manager egress is on by default, but allowlisting arbitrary domains is not allowed (as of July 2026). Instead, we recommend using the Maton MCP server, which doesn't require network allowlisting.

Team / Enterprise plans

Network egress is disabled by default. An organization owner must enable it:

Open Settings → Capabilities → "Code execution and file creation."
Select "Allow network egress to package managers and specific domains."
Add maton.ai to the allowed-domains list.

Refer to Anthropic's network access in Claude for more details.
