How to integrate Linear MCP with OpenCode

This guide explains how to connect Linear MCP to OpenCode using Composio Connect, which simplifies OAuth, API changes, and reliability concerns.

There are two ways to set this up:

Also integrate Linear with

Why use Composio?

Composio provides a single MCP server or CLI tool that exposes a set of meta-tools, allowing you to:

  • Connect to 1,000+ apps with on-demand tool loading, so you do not fill your LLM context window with unnecessary tool definitions.
  • Use programmatic tool calling through a remote Bash tool, letting LLMs write their own code to handle complex tool chaining. This reduces back-and-forth for frequent tool calls.
  • Handle large tool responses outside the LLM context to keep conversations lean.

Connect Linear with OpenCode

Option 1: Using Composio CLI

1. Install Composio CLI

Install the Composio CLI, authenticate, and initialize your project:

bash
# Install the Composio CLI
curl -fsSL https://composio.dev/install | bash

# Authenticate with Composio
composio login

During login, you will be redirected to the sign-in page. Finish the flow and you are all set.

2. Authorize Linear

Once the CLI is installed, it is essentially done. Give OpenCode access to your apps with these steps:

  1. Launch OpenCode.
  2. Prompt it to "Authenticate with Linear Composio".
  3. Complete the authentication and authorization flow, and your Linear integration is all set.
  4. Start asking anything you want.

Option 2: Using Composio MCP

You can also connect Linear to OpenCode by adding Composio as an MCP server through the OpenCode CLI.

1. Add the Composio MCP server

bash
opencode mcp add

This launches an interactive prompt.

2. Fill in the fields

FieldValue
Namecomposio
Typeremote
URLhttps://connect.composio.dev/mcp
Require OAuthYes
Have client IDNo
OpenCode MCP server interactive prompt for Composio

Alternatively, you can skip the interactive prompt and paste the configuration directly into your OpenCode config file.

Open your global OpenCode config:

bash
open ~/.config/opencode/opencode.json

Add this under the mcp key and save the file.

bash
{
  "mcp": {
    "composio": {
      "type": "remote",
      "url": "https://connect.composio.dev/mcp",
      "enabled": true
    }
  }
}

3. Authenticate

Authenticate the Composio MCP server you just added:

bash
opencode mcp auth composio

This opens a browser session. Authorize Composio and you are done.

4. Verify installation

bash
opencode mcp list

5. Connect Linear with OpenCode

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

For example, ask it 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 to Linear.

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

Supported Tools & Triggers

Tools
Triggers
Create linear attachmentCreates a new attachment and associates it with a specific, existing linear issue.
Create a commentCreates a new comment on a specified linear issue.
Create linear issueCreates a new issue in a specified linear project and team, requiring a title and description, and allowing for optional properties like assignee, state, priority, cycle, and due date.
Get create issue default paramsFetches a linear team's default issue estimate and state, useful for pre-filling new issue forms.
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.

Way Forward

Now that Linear is connected, extend your setup by connecting the other apps you already use every day, so your agent can run true cross-app workflows end to end.

  • Connect Calendar to turn threads into scheduled meetings automatically.
  • Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
  • Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
  • Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.

Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single MCP endpoint, your agent can coordinate multiple tools safely and reliably in one conversation.

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 OpenCode?

Yes, you can. OpenCode 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.
