lin

Structured output — JSONL for lists and searches, NDJSON for multi-id gets, JSON or YAML on request, errors to stderr with fixable_by and a hint

LLM-optimized docs — lin usage in under 1,000 tokens, with a fuller usage page per command group

Smart IDs — accepts issue keys, UUIDs or URL fragments interchangeably

Customers and requests, first-class — list by tier, status, owner, domain or revenue, and pull the feedback attached to an issue or project

Rich integration attachments — link GitHub PRs and issues, GitLab MRs, Slack threads (optionally synced) and Discord messages

A pretty mode for humans — --format pretty renders a terminal card for reading an entity, and --full adds relations and comments

Item-level misses do not lose the batch — a missing id becomes an @unresolved line on stdout with exit 0; only command-level failures exit non-zero

Multi-user MCP — one lin mcp server serves several people, each principal's calls pinned to their own stored workspace

Fails closed on identity — LIN_REQUIRE_IDENTITY means a call missing its identity is refused rather than falling back to the operator's default

Browser self-enrollment — a principal minted without a binding pastes their own Linear API key during OAuth approval; it is validated, stored keychain-first, and bound automatically

One slot, one organization — a key resolving to a different Linear org is refused rather than silently re-pointing the slot

Read-back for filesystem-free clients — a built-in read-only fs MCP tool returns downloaded files, images as image blocks

Zero runtime dependencies — a single static Go binary
