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

# 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`:

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

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

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

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:**

{
  "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

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:

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.

Pagination

Linear uses Relay-style cursor-based pagination with `first/after` and `last/before` arguments.

# First page
POST /linear/graphql
{"query": "{ issues(first: 10) { nodes { id identifier title } pageInfo { hasNextPage endCursor } } }"}

# Next page using endCursor
POST /linear/graphql
{"query": "{ issues(first: 10, after: \"CURSOR_VALUE\") { nodes { id identifier title } pageInfo { hasNextPage endCursor } } }"}

Response includes `pageInfo`:

{
  "data": {
    "issues": {
      "nodes": [...],
      "pageInfo": {
        "hasNextPage": true,
        "endCursor": "4c7b33c8-dabf-47ce-9d30-7f286f9463be"
      }
    }
  }
}

Code Examples

JavaScript

const response = await fetch('https://gateway.maton.ai/linear/graphql', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    query: `{ issues(first: 10) { nodes { id identifier title state { name } } } }`
  })
});
const data = await response.json();

Python

import os
import requests

response = requests.post(
    'https://gateway.maton.ai/linear/graphql',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'query': '{ issues(first: 10) { nodes { id identifier title state { name } } } }'
    }
)
data = response.json()

Notes

Linear uses GraphQL exclusively (no REST API)

Issue identifiers like `MTN-527` can be used in place of UUIDs for the `id` parameter

Priority values: 0 = No priority, 1 = Urgent, 2 = High, 3 = Medium, 4 = Low

Workflow state types: `backlog`, `unstarted`, `started`, `completed`, `canceled`

The GraphQL schema is introspectable at `https://api.linear.app/graphql`

Use `searchIssues(term: "...")` for full-text search across issues

Some mutations (delete, create labels/projects) may require additional OAuth scopes. If you receive a scope error, contact Maton support at support@maton.ai with the specific operations/APIs you need and your use-case

Error Handling

| Status | Meaning |

|--------|---------|

| 400 | Missing Linear connection or GraphQL validation error |

| 401 | Invalid or missing Maton API key |

| 403 | Insufficient OAuth scope for the operation |

| 429 | Rate limited |

| 4xx/5xx | Passthrough error from Linear API |

GraphQL errors are returned in the `errors` array:

{
  "errors": [
    {
      "message": "Invalid scope: `write` required",
      "extensions": {
        "type": "forbidden",
        "code": "FORBIDDEN",
        "statusCode": 403
      }
    }
  ]
}

Troubleshooting: API Key Issues

1. Check that the `MATON_API_KEY` environment variable is set:

echo $MATON_API_KEY

2. Verify the API key is valid by listing connections:

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

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with `linear`. For example:

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

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