Linear MCP — Auth Setup

Linear uses personal API keys to authenticate requests to your workspace.

1. Get your credentials

  1. Open the Linear API settings page (opens Linear — we never see your key)
  2. Under Personal API keys, click Create new API key
  3. Give it a label and copy the key — it will not be shown again after you leave the page

2. Set environment variables

macOS / Linux — add to ~/.zshrc or ~/.bashrc:

export LINEAR_API_KEY=YOUR_API_KEY_HERE

Then run source ~/.zshrc (or open a new terminal).

Windows — run in Command Prompt (then restart):

setx LINEAR_API_KEY "YOUR_API_KEY_HERE"

3. Verify

npx claude-skills doctor

You should see ✅ next to the Linear MCP entry. If you see ❌, confirm the key is set: echo $LINEAR_API_KEY.

4. Restart Claude Code

Quit and reopen Claude Code (or run /mcp list inside Claude Code to confirm the Linear MCP appears).
