Linear API

Linear API: The Developer Interface for Modern Project Management

Linear's API is what happens when a project management tool actually respects developers. Built on GraphQL from day one, it gives you strongly-typed queries, predictable responses, and an interactive explorer that makes building integrations feel more like assembling Lego than fighting documentation.

What You Get

The API covers everything in Linear: issues, projects, cycles, initiatives, teams, labels, and custom fields. GraphQL means you fetch exactly what you need in a single request — no over-fetching, no chaining five REST calls together. The schema is well-documented with introspection built in, so your IDE's autocomplete actually works.

Real-time subscriptions via WebSockets let you react to changes instantly. When an issue moves to "Done" or a comment gets added, your integration knows immediately without polling. Webhooks handle the server-side equivalent with granular event filtering and automatic retry on failed deliveries.

MCP Server: AI Agents Meet Project Management

Linear ships a native MCP server at mcp.linear.app/mcp that lets AI agents like Claude and Cursor interact directly with your project data. Agents can create and edit initiatives, manage project milestones, post updates, handle labels, and load Linear resources by URL. This isn't a wrapper — it's a first-party integration that treats AI agents as first-class citizens in the product workflow.

The MCP server requires a Business plan ($16/user/month). If your team uses AI coding assistants, this is where Linear pulls ahead of competitors. No other project management tool in 2026 offers a native, first-party MCP server. Jira's AI capabilities are locked to Atlassian Intelligence; Asana's AI features are internal-only; Notion's API has no MCP equivalent. Linear is the only platform where your AI coding assistant can directly manage your engineering backlog without third-party middleware.

How Linear's API Compares to Jira's

This is the comparison most teams care about. Jira's REST API is powerful but sprawling — dozens of endpoints with inconsistent naming, verbose JSON responses, and documentation that requires archaeology to navigate. A simple "get issue with project and assignee" takes multiple API calls in Jira. In Linear's GraphQL, it's one query.

Where Jira wins: deep customization (custom issue types, screens, workflows), a marketplace of 3,000+ apps, and enterprise features like advanced permissions and compliance certifications. Where Linear wins: developer experience, API consistency, real-time capabilities, and AI agent integration. If you're building a new integration from scratch, Linear takes hours where Jira can take days.

Authentication and Rate Limits

OAuth 2.0 for production apps, personal access tokens for development and scripts. Rate limiting is generous at 2,000 requests per hour for standard use, with higher limits available on Enterprise plans. The rate limits are per-token, so multiple integrations don't step on each other.

The GraphQL Advantage (and Tradeoff)

Linear's GraphQL-only approach is a deliberate choice. You get type safety, efficient data fetching, and a self-documenting schema. The tradeoff: there's no REST fallback. Teams without GraphQL experience will need to invest time learning the query language. The official TypeScript SDK abstracts much of this away, but developers in Python, Go, or other languages work with raw GraphQL queries or community libraries.

For teams already using GraphQL (common in modern stacks), this is a pure advantage. For teams coming from REST-heavy environments, budget a day or two of ramp-up time. The interactive explorer at developers.linear.app makes the learning curve manageable.

Where Linear's API Falls Short

Linear is opinionated about workflows. If your team's process doesn't map to Linear's Issues → Projects → Cycles → Initiatives hierarchy, the API can't save you. There's no way to fundamentally reshape the data model through the API.

The free tier caps at 2 teams and 250 issues, which growing startups can outgrow quickly. Enterprise pricing isn't published, requiring sales conversations. And while Linear Agent's AI automations are promising, they're still in beta with limited customization as of early 2026.

Pricing

| Plan | Price | API Access |
|------|-------|------------|
| Free | $0 | Full API + webhooks, 2 teams, 250 issues |
| Basic | $10/user/month (annual) | Full API, 5 teams, unlimited issues |
| Business | $16/user/month (annual) | Full API + MCP server + Linear Agent automations |
| Enterprise | Custom | Everything + SAML/SCIM + higher rate limits |

Who Should Use This

Engineering teams already on Linear who want to automate workflows, build custom dashboards, or integrate AI agents into their project management. If you're evaluating project management tools and API quality matters, Linear's is best-in-class for the category. Teams heavily invested in AI coding assistants should seriously consider the Business plan for MCP access — it's a capability no competitor currently matches.

Common Questions

Q: How does Linear's API compare to Jira's?

Linear's GraphQL API is significantly easier to work with than Jira's REST API. Queries are more flexible, documentation is better, and the developer experience is night-and-day different. Jira wins on customization depth and ecosystem size.

Q: Can AI agents fully manage my Linear workspace?

With the MCP server on Business plans, agents can create issues, manage projects, post updates, and handle most day-to-day operations. They can't change workspace settings or manage billing. The Linear Agent (beta) adds automated triage and workflow rules.

Q: Is there a sandbox or test environment?

No dedicated sandbox. Most developers use a separate test workspace on the Free plan for development and testing.

Q: What SDKs are available?

Official TypeScript/JavaScript SDK. Community SDKs exist for Python and Go. The GraphQL schema is well-documented enough that generating clients in other languages is straightforward.

Q: What's the rate limit and how is it enforced?

2,000 requests per hour per authentication token. Enterprise plans get higher limits. Rate limits are per-token, so separate integrations don't compete for quota. Standard rate limit headers are included in responses for client-side backoff implementation.
