Linear MCP Integration

Use Linear MCP server functions to interact with Linear's project management system.

Prerequisites

• Linear MCP server configured and available
• Authentication: Linear API token configured in MCP server
• Access to Linear workspace

Quick Start

Get issue details:

mcp_Linear_get_issue({
  id: "LIN-123",
  includeRelations: true // get related/blocking issues
})

List issues:

mcp_Linear_list_issues({
  team: "Engineering",
  state: "In Progress"
})

Usage Patterns for PR Review

Fetch Issue Requirements

Step 1: Extract Issue ID from PR

• Look for Linear issue references in PR title/body (e.g., LIN-123, [LIN-123])
• Extract issue identifier

Step 2: Get Issue Details

mcp_Linear_get_issue({
  id: "LIN-123", // extracted from PR
  includeRelations: true // to get blocking/related issues
})

Step 3: Extract Requirements

• Parse issue description for acceptance criteria
• Check labels for feature tags
• Review comments for additional context
• Check relatedTo and blocks for dependencies

Validate PR Completeness

Check if PR addresses all requirements:

1. Get issue details with mcp_Linear_get_issue
2. Parse issue description for:

• Acceptance criteria (checkboxes, numbered lists)
• Feature requirements
• Technical specifications

3. Compare PR changes against requirements
4. Identify gaps or missing implementations

Update Issue Status

After PR review:

• Use mcp_Linear_update_issue to:
  • Update status (e.g., "In Review", "Ready for QA")
  • Add comments with review findings
  • Link related issues

Create Review Comments

Post review findings to Linear:

mcp_Linear_create_comment({
  issueId: "LIN-123",
  body: "## PR Review Summary\n\n✅ Requirements met: ...\n⚠️ Gaps identified: ..."
})

Common Workflows

PR Review with Issue Validation

1. Extract issue reference from PR title/body
2. Fetch issue using mcp_Linear_get_issue
3. Parse requirements from issue description
4. Review PR changes against requirements
5. Create comment on Linear issue with review summary
6. Update issue status if needed

Issue Discovery

1. List issues for a team/project using mcp_Linear_list_issues
2. Filter by state, assignee, or labels
3. Get details for relevant issues
4. Cross-reference with PR changes

Integration with GitHub

When reviewing PRs:

1. Extract Linear issue references from PR title/body
2. Use Linear MCP to fetch issue requirements
3. Validate PR changes against requirements
4. Post review findings back to Linear issue
