Linear MCP Server Extension for Zed

This extension integrates my Linear MCP Server into Zed's AI Assistant, enabling direct interaction with Linear through Zed.

Features

• ✨ Full Linear API integration through MCP
• 🔄 Create, update, and manage issues directly from Zed
• 📝 Comment management (create, update, delete, resolve)
• 📊 Project and milestone management
• 👥 Multiple workspace support
• 🔍 Advanced issue search and filtering
• 🏷️ Label management
• 📎 Parent/child issue relationships

Setup

Option 1: Developer Token

Go to Linear: Workspace Settings > API > OAuth application > Create or select an application (e.g., "Cline MCP"). Under "Developer Token", click "Create & copy token". Select "Application" as the actor and copy the generated token.

Option 2: Personal API Key

Go to Linear: Your Personal Settings > API > Personal API Keys. Click "Create key", give it a label (e.g., "Cline MCP"), and copy the generated key.

Setting up Zed

Take the key you just received and add them to your Zed settings.json, in the "context_servers" field

{
  "context_servers": {
    "mcp-server-linear": {
      "settings": {
        "linear_api_key": "<LINEAR_API_KEY>",
        "tool_prefix": "<optional tool prefix>"
      }
    }
  }
}

You can also add these keys directly into an Agent profile, for example:

{
  "assistant": {
    "profiles": {
      "write": {
        "name": "Write",
        "context_servers": {
          "mcp-server-linear": {
            "settings": {
              "linear_api_key": "<LINEAR_API_KEY>",
              "tool_prefix": "company1" // optional
            }
          }
        }
      }
    }
  }
}

Multiple Workspace Support

If you work with multiple Linear workspaces, you can use the optional tool_prefix setting to prefix all Linear tools. This helps distinguish between different workspaces:

{
  "context_servers": {
    "mcp-server-linear": {
      "settings": {
        "linear_api_key": "<LINEAR_API_KEY>",
        "tool_prefix": "company1"
      }
    }
  }
}

With this configuration:

• Tool names will be prefixed (e.g., company1_linear_create_issue)
• Makes it clear which workspace each tool is operating on
• Prevents conflicts when working with multiple Linear instances

Multiple Simultaneous Installations

You can run multiple instances of the MCP server simultaneously by configuring different command blocks with unique TOOL_PREFIX values:

{
  "context_servers": {
    "mcp-server-linear": {
      // provided through Zed extension
      "settings": {
        "linear_api_key": "<LINEAR_API_KEY>",
        "tool_prefix": "company1"
      }
    },
    "linear-workspace2": {
      // provided through npx
      "settings": {},
      "command": {
        "command": "npx",
        "args": ["-y", "mcp-server-linear"],
        "env": {
          "LINEAR_ACCESS_TOKEN": "<LINEAR_API_KEY_2>",
          "TOOL_PREFIX": "workspace2"
        }
      }
    }
  }
}

Each instance will have its tools prefixed with the specified TOOL_PREFIX, allowing you to interact with multiple Linear workspaces simultaneously.
