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

  1. Get a personal API key from Linear Settings > API > Personal API keys
  2. 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

Workflow States

Linear uses 

WorkflowState
objects with a 
type
field. 6 state types:

TypeDescription
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

        "teamIds": ["TEAM_UUID"]
      }
    }
  }' | python3 -m json.tool

Pagination

Linear uses Relay-style cursor pagination:

# First page
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 } pageInfo { hasNextPage endCursor } } }"}' | python3 -m json.tool

# Next page — use endCursor from previous response
curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "{ issues(first: 20, after: \"CURSOR_FROM_PREVIOUS\") { nodes { identifier title } pageInfo { hasNextPage endCursor } } }"}' | python3 -m json.tool

Default page size: 50. Max: 250. Always use 

first: N
to limit results.

Typical Workflow

  1. Query teams to get team IDs and keys
  2. Query workflow states for target team to get state UUIDs
  3. List or search issues to find what needs work
  4. Create issues with team ID, title, description, priority
  5. Update status by setting 
    stateId
    to the target workflow state
  6. Add comments to track progress
  7. Mark complete by setting 
    stateId
    to the team's "completed" type state

Rate Limits

  • 5,000 requests/hour per API key
  • 3,000,000 complexity points/hour
  • Use 
    first: N
    to limit results and reduce complexity cost
  • Monitor 
    X-RateLimit-Requests-Remaining
    response header

Important Notes

  • Always use 
    terminal
    tool with 
    curl
    for API calls — do NOT use 
    web_extract
    or 
    browser
  • Always check the 
    errors
    array in GraphQL responses — HTTP 200 can still contain errors
  • If 
    stateId
    is omitted when creating issues, Linear defaults to the first backlog state
  • The 
    description
    field supports Markdown
  • Use 
    python3 -m json.tool
    or 
    jq
    to format JSON responses for readability
