Merge Gateway — Claude Code Skills

A Claude Code plugin with skills for integrating with, building on, and migrating to Merge Gateway.

Installation

Add the plugin marketplace, then install:

claude plugin marketplace add merge-api/merge-gateway-skills
claude plugin install merge-gateway

That's it — the skills are ready to use immediately.

Alternative: manual install

If you prefer to add skills directly to a single project:

git clone https://github.com/merge-api/merge-gateway-skills.git
cp -r merge-gateway-skills/.claude/skills/ /path/to/your/project/.claude/skills/

Getting Started

After installing, open Claude Code and try one of these:

Integrate Gateway into your project

/merge-gateway:gateway-implement

Build an agent with tool calling

/merge-gateway:build-agent

Explore advanced Gateway features

/merge-gateway:gateway-features

Migrate from another provider

/merge-gateway:migrate-openrouter
/merge-gateway:migrate-direct-sdk
/merge-gateway:migrate-bedrock
/merge-gateway:migrate-azure
/merge-gateway:migrate-litellm

Or just describe what you want — Claude will pick the right skill:

• "Add Merge Gateway to this project"
• "Build a tool-use agent that can search the web"
• "Migrate this project from OpenRouter to Merge Gateway"
• "Switch from Bedrock to Merge Gateway"
• "Show me Gateway's advanced features like tags and routing"

What You'll Need

• A Merge Gateway API key (mg_...) — get one from the Gateway dashboard

How It Works

All skills route your LLM calls through Merge Gateway using the Merge Gateway SDK, available in both Python and TypeScript:

Python:

from merge_gateway import MergeGateway

client = MergeGateway(api_key="mg_...")

response = client.responses.create(
    model="openai/gpt-4o",
    input=[{"type": "message", "role": "user", "content": "Hello!"}],
)
print(response.output[0].content[0].text)

TypeScript:

import { MergeGateway } from "merge-gateway-sdk";

const client = new MergeGateway({ apiKey: "mg_..." });

const response = await client.responses.create({
  model: "openai/gpt-4o",
  input: [{ type: "message", role: "user", content: "Hello!" }],
});
console.log(response.output[0].content[0].text);

Key conventions:

• Model names use provider/model format (e.g., openai/gpt-4o, anthropic/claude-sonnet-4-20250514)
• Auth uses a single mg_... API key for all providers
