Linear Automation via Rube MCP

Automate Linear operations through Composio's Linear toolkit via Rube MCP.

Toolkit docs: composio.dev/toolkits/linear

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Linear connection via RUBE_MANAGE_CONNECTIONS with toolkit linear
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit linear
3. If connection is not ACTIVE, follow the returned auth link to complete Linear OAuth
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. Manage Issues

When to use: User wants to create, search, update, or list Linear issues

Tool sequence:

1. LINEAR_GET_ALL_LINEAR_TEAMS - Get team IDs [Prerequisite]
2. LINEAR_LIST_LINEAR_STATES - Get workflow states for a team [Prerequisite]
3. LINEAR_CREATE_LINEAR_ISSUE - Create a new issue [Optional]
4. LINEAR_SEARCH_ISSUES / LINEAR_LIST_LINEAR_ISSUES - Find issues [Optional]
5. LINEAR_GET_LINEAR_ISSUE - Get issue details [Optional]
6. LINEAR_UPDATE_ISSUE - Update issue properties [Optional]

Key parameters:

• team_id: Team ID (required for creation)
• title: Issue title
• description: Issue description (Markdown supported)
• state_id: Workflow state ID
• assignee_id: Assignee user ID
• priority: 0 (none), 1 (urgent), 2 (high), 3 (medium), 4 (low)
• label_ids: Array of label IDs

Pitfalls:

• Team ID is required when creating issues; use GET_ALL_LINEAR_TEAMS first
• State IDs are team-specific; use LIST_LINEAR_STATES with the correct team
• Priority uses integer values 0-4, not string names

2. Manage Projects

When to use: User wants to create or update Linear projects

Tool sequence:

1. LINEAR_LIST_LINEAR_PROJECTS - List existing projects [Optional]
2. LINEAR_CREATE_LINEAR_PROJECT - Create a new project [Optional]
3. LINEAR_UPDATE_LINEAR_PROJECT - Update project details [Optional]

Key parameters:

• name: Project name
• description: Project description
• team_ids: Array of team IDs associated with the project
• state: Project state (e.g., 'planned', 'started', 'completed')

Pitfalls:

• Projects span teams; they can be associated with multiple teams

3. Manage Cycles

When to use: User wants to work with Linear cycles (sprints)

Tool sequence:

1. LINEAR_GET_ALL_LINEAR_TEAMS - Get team ID [Prerequisite]
2. LINEAR_GET_CYCLES_BY_TEAM_ID / LINEAR_LIST_LINEAR_CYCLES - List cycles [Required]

Key parameters:

• team_id: Team ID for cycle operations
• number: Cycle number

Pitfalls:

• Cycles are team-specific; always scope by team_id

4. Manage Labels and Comments

When to use: User wants to create labels or comment on issues

Tool sequence:

1. LINEAR_CREATE_LINEAR_LABEL - Create a new label [Optional]
2. LINEAR_CREATE_LINEAR_COMMENT - Comment on an issue [Optional]
3. LINEAR_UPDATE_LINEAR_COMMENT - Edit a comment [Optional]

Key parameters:

• name: Label name
• color: Label color (hex)
• issue_id: Issue ID for comments
• body: Comment body (Markdown)

Pitfalls:

• Labels can be team-scoped or workspace-scoped
• Comment body supports Markdown formatting

5. Custom GraphQL Queries

When to use: User needs advanced queries not covered by standard tools

Tool sequence:

1. LINEAR_RUN_QUERY_OR_MUTATION - Execute custom GraphQL [Required]

Key parameters:

• query: GraphQL query or mutation string
• variables: Variables for the query

Pitfalls:

• Requires knowledge of Linear's GraphQL schema
• Rate limits apply to GraphQL queries

Common Patterns

ID Resolution

Team name -> Team ID:

1. Call LINEAR_GET_ALL_LINEAR_TEAMS
2. Find team by name in response
3. Extract id field

State name -> State ID:

1. Call LINEAR_LIST_LINEAR_STATES with team_id
2. Find state by name
3. Extract id field

Pagination

• Linear tools return paginated results
• Check for pagination cursors in responses
• Pass cursor to next request for additional pages

Known Pitfalls

Team Scoping:

• Issues, states, and cycles are team-specific
• Always resolve team_id before creating issues

Priority Values:

• 0 = No priority, 1 = Urgent, 2 = High, 3 = Medium, 4 = Low
• Use integer values, not string names
