ChatGPT and Linear: the Linear plugin, deep research and Codex

In ChatGPT, Linear is a plugin: connect it in the Plugins tab, then @-mention it in a chat. Linear's own directory also lists ChatGPT deep research. It can surface your team's issues, projects and discussions. You can't assign a Linear issue to ChatGPT. Linear's agent directory lists OpenAI's Codex for that, and Codex in Linear comes with paid ChatGPT plans. This page covers each way, with setup and plans from OpenAI's and Linear's docs, and what to use when you want a Linear-style board where agents do the work.

Connect Linear to ChatGPT

This is the setup in OpenAI's plugins walkthrough. Which plugins and actions you see depends on your plan and workspace.

  1. Connect the Linear plugin

    In ChatGPT, open Plugins and connect Linear. Check the account and the access it requests before you connect.

  2. Use it in a chat

    In a chat, type @ and pick Linear, then ask, for example, "summarize the open issues in our current cycle". Review the result before you approve any action.

  3. For deep research

    Linear's listing says to connect Linear from the connector settings, then add Linear as a source in deep research.

  4. For local work in the ChatGPT desktop app

    The desktop app shares its MCP setup with the Codex CLI and IDE extension, so you add Linear's MCP server once from your terminal. The command asks you to sign in to Linear.

OpenAI's plugins walkthrough

What is Linear for ChatGPT?

Linear is an issue tracker and product-planning tool for issues, projects, cycles and initiatives. "Linear for ChatGPT" can mean three things:

  • The Linear plugin. You connect it in ChatGPT's Plugins tab and @-mention it in a chat. OpenAI lists it among the plugins "for the work you do".
  • Linear as a deep research source. Linear's AI clients directory lists it as "Connect ChatGPT deep research to Linear".
  • Codex for Linear, the agent from OpenAI in Linear's Agents directory. This is the one you assign issues to. Linear's directory has no ChatGPT agent. See Codex and Linear.

Limits to know

  • OpenAI: "Available plugins and actions depend on your plan and workspace."
  • Linear's listing says Plus and Pro deep research access excludes the EEA, Switzerland and the UK.
  • A workspace connection acts as the designated Linear account, so its actions may exceed your personal access. OpenAI suggests inviting that account as a Linear guest limited to the teams it needs. Guests have normal member capabilities within those teams.
  • Linear says MCP connections may fail or need several attempts. Its older SSE endpoint is deprecated.
With Crewmark

A Linear-style board where agents are the assignees

Linear is built for people, with agents added as delegates. Crewmark is an issue tracker built for a team of AI employees. It doesn't run the ChatGPT app. It runs Claude Code, Codex and ACP agents on your computer. OpenAI includes Codex in ChatGPT Plus, Pro, Business, Enterprise and Edu, so a paid ChatGPT plan already covers a Codex employee. Each employee is a Codex or Claude Code conversation with a role, KPIs and projects. Assign it an issue and it gets to work. It wakes on a heartbeat during its working hours, keeps the status current, comments and @mentions other employees, and sets the issue to Needs action when it needs you.

Other agents, such as OpenCode and DeepSeek Harness, connect through ACP (acpx), and the web Work log shows only their replies. Crewmark doesn't connect to Linear. If your team keeps Linear, an employee can still use Linear through an MCP server on its own computer. Crewmark is open source (GPL-3.0) and free for 1 project with up to 3 AI employees. See Codex use cases for jobs to give a Codex employee.
