Introduction

Cowork is Anthropic's AI agent for knowledge work. Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks.

This guide walks you through the easiest and most secure way to connect your Linear account to Cowork via Composio Connect, enabling it to create a new bug for team Mobile, add a comment to issue LIN-123, list all cycles for the Design team, and more such actions on your behalf without compromising your account security.

4. Connect your Linear account

Back in Cowork, ask the agent to connect to Linear or give it any Linear-related task.

For example, ask Cowork to:

  • "Create a new bug for team Mobile"
  • "Add a comment to issue LIN-123"
  • "List all cycles for the Design team"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Linear account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Linear through MCP without you sharing account credentials directly with the agent.

What is the Linear MCP server, and what's possible with it?

The Linear MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Linear account. It provides structured and secure access to your team's issues, projects, and workflows, so your agent can perform actions like creating issues, posting comments, managing attachments, organizing teams, and automating project tracking on your behalf.

  • Automated issue creation and management: Instantly create new Linear issues, update existing ones, or archive issues to keep your team’s backlog organized and up to date.
  • Commenting and collaboration: Post comments on issues, facilitate team discussions, and keep everyone in the loop without manual effort.
  • Attachment handling: Add or download attachments to and from issues, making it easy to share files or reference important documents right from Linear.
  • Team and cycle insights: Retrieve all teams, fetch cycles (sprints) by team ID, and get default issue parameters to help your agent contextualize and optimize planning activities.
  • Personalized workspace access: Identify the current user, fetch their profile information, and tailor actions or queries to individual team members for smarter automation.

Create a labelCreates a new label in linear for a specified team, used to categorize and organize issues.
Delete issueArchives an existing linear issue by its id, which is linear's standard way of deleting issues; the operation is idempotent.
Get all teamsRetrieves all teams from the linear workspace without requiring any parameters.
Download issue attachmentsDownloads a specific attachment from a linear issue; the `file name` must include the correct file extension.
Get current userGets the currently authenticated user's id, name, email, and other profile information.
Get cycles by team IDRetrieves all cycles for a specified linear team id; cycles are time-boxed work periods (like sprints) and the team id must correspond to an existing team.
Get Linear issueRetrieves an existing linear issue's comprehensive details, including title, description, attachments, and comments.
Get all cyclesRetrieves all cycles (time-boxed iterations for work) from the linear account; no filters are applied.
List Linear issuesLists non-archived linear issues; if project id is not specified, issues from all accessible projects are returned.
Get labels by teamRetrieves all labels associated with a given team id in linear; the team id must refer to an existing team.
List linear projectsRetrieves all projects from the linear account.
List Linear statesRetrieves all workflow states for a specified team in linear, representing the stages an issue progresses through in that team's workflow.
Get teams by projectRetrieves all teams, including their members, and filters each team's associated projects by the provided 'project id'.
List Linear usersLists all users in the linear workspace with their ids, names, emails, and active status.
Remove label from Linear issueRemoves a specified label from an existing linear issue using their ids; successful even if the label isn't on the issue.
Run Query or MutationWildcard action that executes any graphql query or mutation against the linear api.
Update issueUpdates an existing linear issue using its `issue id`; requires at least one other attribute for modification, and all provided entity ids (for state, assignee, labels, etc.

Available tools and triggers

After setup, the supported Linear tools and triggers listed on this page are available to Cowork through Composio Connect.

You can now ask Cowork to handle Linear workflows in natural language, from quick summaries and drafting tasks to more complex multi-step work across connected apps.

How to build Linear MCP Agent with another framework

FAQ

What are the differences in Tool Router MCP and Linear MCP?

With a standalone Linear MCP server, the agents and LLMs can only access a fixed set of Linear tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Linear and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Linear tools.

Can I manage the permissions and scopes for Linear while using Tool Router?

Yes, absolutely. You can configure which Linear scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Linear data and credentials are handled as safely as possible.
