  Linear API integration with managed OAuth. Query and manage issues, projects, teams, cycles, and labels using GraphQL.
  Use this skill when users want to create, update, or query Linear issues, search for tasks, manage projects, or track work.
  For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).
  Requires network access and valid Maton API key.

# Linear

Access the Linear API with managed OAuth authentication. Query and manage issues, projects, teams, cycles, labels, and comments using GraphQL.

## Quick Start

```bash
# Get current user
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': '{ viewer { id name email } }'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/linear/graphql', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

## Base URL

```
https://gateway.maton.ai/linear/graphql
```

All requests use POST to the GraphQL endpoint. The gateway proxies requests to `api.linear.app` and automatically injects your OAuth token.

## Authentication

All requests require the Maton API key in the Authorization header:

```
Authorization: Bearer $MATON_API_KEY
```

**Environment Variable:** Set your API key as `MATON_API_KEY`:

```bash
export MATON_API_KEY="YOUR_API_KEY"
```

### Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)
2. Go to [maton.ai/settings](https://maton.ai/settings)
3. Copy your API key

## Connection Management

Manage your Linear OAuth connections at `https://ctrl.maton.ai`.

### List Connections

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=linear&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Create Connection

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'linear'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Get Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

**Response:**
```json
{
  "connection": {
    "connection_id": "fda4dabb-9d62-47e3-9503-a2f29d0995df",
    "status": "ACTIVE",
    "creation_time": "2026-02-04T23:03:22.676001Z",
    "last_updated_time": "2026-02-04T23:03:51.239577Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "linear",
    "metadata": {}
  }
}
```

Open the returned `url` in a browser to complete OAuth authorization.

### Delete Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Specifying Connection

If you have multiple Linear connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': '{ viewer { id name } }'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/linear/graphql', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Maton-Connection', 'fda4dabb-9d62-47e3-9503-a2f29d0995df')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If omitted, the gateway uses the default (oldest) active connection.

## API Reference

Linear uses a GraphQL API. All operations are sent as POST requests with a JSON body containing the `query` field.
