description	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
2. Go to 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.

{
  "data": {
    "issues": {

        "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 [e-mail] 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
