## What it does

The server provides access to Carbon Arc infrastructure over Streamable HTTP at `https://mcp.carbonarc.ai`. It connects your coding assistant to inference tools and agent decision primitives without local runtime setup.

Authentication uses OAuth 2.0 paired with Dynamic Client Registration. Requests fail without an API token generated in your user profile. You can register an account and retrieve this key at `https://app.carbonarc.co/pricing`.

## Requirements
- Remote server: `https://mcp.carbonarc.ai`

## Install

### Claude Code (native platform)

**Platform CLI: remote server**
```bash
claude mcp add --transport http mcp https://mcp.carbonarc.ai
```

### Codex

**Platform CLI: remote server**
```bash
codex mcp add carbon-arc --url https://mcp.carbonarc.ai
```

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "carbon-arc": {
            "url": "https://mcp.carbonarc.ai"
        }
    }
}
```

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "carbon-arc": {
            "type": "http",
            "url": "https://mcp.carbonarc.ai"
        }
    }
}
```

### Gemini CLI

**Platform CLI: remote server**
```bash
gemini mcp add -t http carbon-arc https://mcp.carbonarc.ai
```

## When to use it
- connect Carbon Arc infrastructure to a Claude Code session
- route inference tasks through an external HTTP endpoint
- authenticate assistant requests via OAuth 2.0
- access agent decision primitives without running a local server

## Example prompts
- Check the connection to the Carbon Arc endpoint at `https://mcp.carbonarc.ai`
- Execute an inference task using the connected Carbon Arc server
- Verify the authorization status of the Carbon Arc token
