Linear — Issue & Project Management
Manage Linear issues, projects, and teams directly via the GraphQL API using curl. No MCP server, no OAuth flow, no extra dependencies.
Setup
- Get a personal API key from Linear Settings > Account > Security & access > Personal API keys (URL: https://linear.app/settings/account/security). Note: the org-level Settings > API page only shows OAuth apps and workspace-member keys, not personal keys.
- Set
LINEAR_API_KEY in your environment (via hermes setup or your env config)
API Basics
- Endpoint:
https://api.linear.app/graphql (POST)
- Auth header:
Authorization: $LINEAR_API_KEY (no "Bearer" prefix for API keys)
- All requests are POST with
Content-Type: application/json
- Both UUIDs and short identifiers (e.g.,
ENG-123) work for issue(id:)
Base curl pattern:
curl -s -X POST https://api.linear.app/graphql \
-H "Authorization: $LINEAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query": "{ viewer { id name } }"}' | jq .
Python helper script (ergonomic alternative)
For faster one-liners that don't need hand-written GraphQL, this skill ships a stdlib Python CLI at scripts/linear_api.py. Zero dependencies. Same auth (reads LINEAR_API_KEY).
SCRIPT=$(dirname "$(find ~/.hermes -path '*skills/productivity/linear/scripts/linear_api.py' 2>/dev/null | head -1)")/linear_api.py
python3 "$SCRIPT" whoami
python3 "$SCRIPT" list-teams
python3 "$SCRIPT" get-issue ENG-42
python3 "$SCRIPT" get-document 38359beef67c
python3 "$SCRIPT" raw 'query { viewer { name } }'
All subcommands: whoami, list-teams, list-projects, list-states, list-issues, get-issue, search-issues, create-issue, update-issue, update-status, add-comment, list-documents, get-document, search-documents, raw. Run with --help for flags.
Use the script when: you want a quick answer without crafting GraphQL. Use curl when: you need a query the script doesn't wrap, or you want to compose filters inline.
Workflow States
Linear uses WorkflowState objects with a type field. 6 state types:
| Type | Description |
|---|
triage | Incoming issues needing review |
backlog | Acknowledged but not yet planned |
unstarted | Planned/ready but not started |
started | Actively being worked on |
completed | Done |
canceled | Won't do |
Each team has its own named states (e.g., "In Progress" is type started). To change an issue's status, you need the stateId (UUID) of the target state — query workflow states first.
Priority values: 0 = None, 1 = Urgent, 2 = High, 3 = Medium, 4 = Low
