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 } }"}' | python3 -m json.tool
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).
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.
curl -s -X POST https://api.linear.app/graphql \
-H "Authorization: $LINEAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query": "{ issues(first: 20) { nodes { identifier title priority state { name type } assignee { name } team { key } url } pageInfo { hasNextPage endCursor } } }"}' | python3 -m json.tool
List my assigned issues
curl -s -X POST https://api.linear.app/graphql \
-H "Authorization: $LINEAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query": "{ viewer { assignedIssues(first: 25) { nodes { identifier title state { name type } priority url } } } }"}' | python3 -m json.tool
Get a single issue (by identifier like ENG-123)
curl -s -X POST https://api.linear.app/graphql \
-H "Authorization: $LINEAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query": "{ issue(id: \"ENG-123\") { id identifier title description priority state { id name type } assignee { id name } team { key } project { name } labels { nodes { name } } comments { nodes { body user { name } createdAt } } url } }"}' | python3 -m json.tool
Search issues by text
curl -s -X POST https://api.linear.app/graphql \
-H "Authorization: $LINEAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query": "{ issueSearch(query: \"bug login\", first: 10) { nodes { identifier title state { name } assignee { name } url } } }"}' | python3 -m json.tool
Filter issues by state type
curl -s -X POST https://api.linear.app/graphql \
-H "Authorization: $LINEAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"query": "{ issues(filter: { state: { type: { in: [\"started\"] } } }, first: 20) { nodes { identifier title state { name } assignee { name } } } }"}' | python3 -m json.tool
The trailing hex segment is the slugId. Example: https://linear.app/nousresearch/document/rfc-hermes-permission-gateway-discord-38359beef67c → slugId is 38359beef67c.
Important schema detail: the Markdown body is in the content field. The ProseMirror JSON is in contentState (not contentData — that field does not exist and the API returns 400).
Fetch a document by slugId
document(id:) only accepts UUIDs. To fetch by the URL's hex slug, filter the collection:
