# Linear Automation via Rube MCP

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

## 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
