Linear MCP (multi-workspace, PAT auth)

Connects Claude to Linear's project tracking API using Personal Access Tokens instead of OAuth, solving the official server's session persistence issues and enabling true multi-workspace routing from a single MCP instance. Exposes 57 tools covering teams, issues, projects, cycles, webhooks, notifications, attachments, and full-text search across all entity types. Enforces source attribution at the substrate layer by requiring canonical keys in issue descriptions and blocking duplicate creates through automatic deduplication checks. Destructive operations like webhook deletion use a draft-then-confirm flow with one-hour expiry. Ships with three prompts for triage, project status drafting, and inbox sweeps. Reach for this when you manage issues across multiple Linear workspaces and want PAT-based auth that survives client restarts without re-dancing through OAuth callbacks.
