Linear API Review 2026

GraphQL API, MCP server, webhooks, and developer docs for building Linear integrations and AI agent workflows.

Linear API is the official developer surface for Linear workspaces, combining a GraphQL-first API, schema explorer, OAuth and personal API-key authentication, webhooks, real-time subscription patterns, TypeScript tooling, and a Linear-hosted remote MCP server for AI clients that need secure access to issues, projects, teams, comments, initiatives, and workflow context. The platform is most useful when an engineering organization already uses Linear as its system of record and wants to connect issue tracking to internal dashboards, CI/CD workflows, customer support escalation, product planning, or AI-agent tools without replacing Linear's opinionated workflow model. Linear's public pricing page lists a Free plan at $0 with unlimited members, 2 teams, 250 issues, Agent platform access, Linear Agent beta access, and API and webhook access. The Basic plan is listed at $10 per user per month when billed yearly and adds 5 teams, unlimited issues, unlimited file uploads, and admin roles. The Business plan is listed at $16 per user per month when billed yearly and adds unlimited teams, private teams and guests, Triage Intelligence, Linear Agent automations beta, Linear Insights, Linear Asks, and Zendesk and Intercom integrations. Enterprise pricing is custom with annual billing and adds invoice or PO billing, SAML and SCIM, granular admin controls, enterprise-grade security, advanced org modeling, migration and onboarding support, priority support, and account management. Linear's pricing page also states that more than 25,000 companies use Linear, which gives buyers a concrete adoption signal beyond feature claims. For AI workflows, Linear documents a remote MCP endpoint at https://mcp.linear.app/mcp using Streamable HTTP transport and OAuth 2.1 with dynamic client registration, with setup guidance for Claude, Claude Code, Codex, Cursor, Visual Studio Code, Windsurf, Zed, Jules, v0 by Vercel, and generic MCP-compatible clients through mcp-remote. Linear's MCP tools are documented for finding, creating, and updating workspace objects such as issues, projects, and comments, and Linear's 2026 MCP changelog describes additional support for initiatives, initiative updates, project milestones, project updates, project labels, image loading, Linear URL resources, and improved tool documentation to reduce token usage. For traditional integrations, the developer documentation centers on GraphQL queries and mutations, webhook event payloads, OAuth scopes, personal API keys, and the official TypeScript SDK, making the API suitable for production systems that need authenticated read and write access rather than simple export-only reporting. The main tradeoffs are that Linear is GraphQL-first rather than REST-first, plan limits affect workspace scale and advanced features, and some AI or automation capabilities are still labeled beta or evolve quickly. Teams should treat Linear's official developer docs, pricing page, MCP docs, security page, and changelog as the authoritative sources when validating current limits, plan availability, and supported client behavior.
