Linear Project Management
Manage Linear issues, cycles, projects, and team workflows via the Linear API (GraphQL) or MCP.
Setup
bash
# Get API key from Linear: Settings → API → Personal API Keys
export LINEAR_API_KEY="lin_api_..."python
import requests
LINEAR_API = "https://api.linear.app/graphql"
HEADERS = {
"Authorization": f"Bearer {LINEAR_API_KEY}",

python

If Linear MCP is installed in .mcp.json:
json
{
"mcpServers": {
"linear": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-linear"],
"env": {"LINEAR_API_KEY": "lin_api_..."}
}
}
}Then Claude can use Linear tools directly without GraphQL code.
Webhooks (receive events)
python
# Linear sends POST to your endpoint on issue create/update
# Payload includes: type, action, data.issue
# Verify with: X-Linear-Signature header
import hmac, hashlib
def verify_signature(payload, signature, secret):
expected = hmac.new(secret.encode(), payload, hashlib.sha256).hexdigest()
return hmac.compare_digest(f"sha256={expected}", signature)
