CLI tool for Linear.app optimized for AI agents. JSON output, smart ID resolution, token-efficient usage commands, and a discover-then-act workflow that keeps agent context small. Works just as well for humans who prefer structured data on the command line.
The official Linear MCP works fine, but it eats up ~13k tokens just by being connected -- before the agent does anything. Linearis takes a different approach: instead of exposing the full API surface upfront, agents discover what they need through a two-tier usage system. linearis usage gives an overview in ~200 tokens, then linearis <domain> usage provides the full reference for one area in ~300-500 tokens. A typical agent interaction costs ~500-700 tokens of context, not ~13k.
The trade-off is coverage. An MCP exposes the entire Linear API; Linearis covers the operations that matter for day-to-day work with issues, comments, cycles, documents, and files. If you need to manage custom workflows, integrations, or workspace settings, the MCP is the better choice.
This project scratches my own itches, and satisfies my own usage patterns of working with Linear: I do work with tickets/issues and comments on the command line; I do not manage projects or workspaces etc. there. YMMV.
npm install -g linearisRequires Node.js >= 22.
linearis auth loginThis opens Linear in your browser, guides you through creating an API key, and stores the token encrypted in ~/.linearis/token.
Alternatively, provide a token directly:
# Via CLI flag
linearis --api-token <token> issues list
# Via environment variable
LINEAR_API_TOKEN=<token> linearis issues listToken resolution order: --api-token flag > LINEAR_API_TOKEN env > ~/.linearis/token > ~/.linear_api_token (deprecated).
All output is JSON. Pipe through jq or similar for formatting.
# Discovery

linearis <domain> usageThe CLI is structured around a discover-then-act pattern that matches how agents work:
- Discover --
linearis usagereturns a compact overview of all domains (~200 tokens). The agent reads this once to understand what's available. - Drill down --
linearis <domain> usagegives the full command reference for one domain (~300-500 tokens). The agent only loads what it needs. - Execute -- All commands return structured JSON. No parsing of human-readable tables or prose.
This means the agent never loads the full API surface into context. It pays for what it uses, one domain at a time.
| Linearis | Linear MCP | |
|---|---|---|
| Context cost | ~500-700 tokens per interaction | ~13k tokens on connect |
| Coverage | Common operations (issues, comments, cycles, docs, files) | Full Linear API |
| Output | JSON via stdout | Tool call responses |
| Setup | npm install -g linearis + bash tool |

Use Linearis when token efficiency matters and you work primarily with issues and related data. Use the MCP when you need full API coverage or tight tool-call integration.
## Linear (project management)
Tool: `linearis` CLI via Bash. All output is JSON.
Discovery: Run `linearis usage` once to see available domains. Run `linearis <domain> usage` for full command reference of a specific domain. Do NOT guess flags or subcommands -- check usage first.
Ticket format: "ABC-123". Always reference tickets by their identifier.
Workflow rules:
- When creating a ticket, ask the user which project to assign it to if unclear.
- For subtasks, inherit the parent ticket's project by default.
- When a task in a ticket description changes status, update the description.
- For progress beyond simple checkbox changes, add a comment instead of editing the description.
File handling: `issues read` returns an `embeds` array with signed download URLs and expiration timestamps. Use `files download` to retrieve them. Use `files upload` to attach new files, then reference the returned URL in comments or descriptions.Add this (or a version adapted to your workflow) to your AGENTS.md or CLAUDE.md so every agent session has it in context automatically.
