+# Linear MCP Setup Guide
+
+This guide shows how to set up Linear MCP (Model Context Protocol) integration to create tickets programmatically.
+
+## Prerequisites
+
+1. **Linear API Key**: You need a Linear API key from your Linear workspace
+   - Go to Linear → Settings → API → Create API Key
+   - Copy the key (starts with `lin_api_...`)
+
+2. **Environment Setup**: Set the Linear API key as an environment variable:
+   ```bash
+   export LINEAR_API_KEY="your_linear_api_key_here"
+   ```
+
+## MCP Configuration
+
+The Linear MCP server configuration has been added to `.continue/mcpServers/linear-mcp.yaml`:
+
+```yaml
+name: Linear MCP
+description: Linear MCP server for creating and managing Linear issues
+
+mcpServers:
+  - name: "Linear"
+    type: "stdio"
+    command: "npx"
+    args: ["@linear/mcp-server"]
+    env:
+      LINEAR_API_KEY: "${LINEAR_API_KEY}"
+```
+
+## Usage
+
+### Option 1: Using the Node.js Script
+
+Run the provided script to create a test ticket:
+
+```bash
+# Set your Linear API key first
+export LINEAR_API_KEY="lin_api_your_key_here"
+
+# Run the script
+node create-linear-ticket.js
+```
+
+### Option 2: Using Continue CLI (when available)
+
+Once the Continue CLI is properly built and the MCP server is connected, you can use MCP tools directly:
+
+```bash
+continue mcp call linear create_issue --title "create test ticket" --description "Test ticket created via MCP"
+```
+
+### Option 3: Direct API Call
+
+The script includes a fallback to use Linear's GraphQL API directly if MCP is not available.
+
+## Testing
+
+To test the MCP setup:
+
+1. Install the Linear MCP server:
+   ```bash
+   npm install -g @linear/mcp-server
+   ```
+
+2. Set your API key:
+   ```bash
+   export LINEAR_API_KEY="your_key_here"
+   ```
+
+3. Run the test script:
+   ```bash
+   node create-linear-ticket.js
+   ```
+
+## Expected Output
+
+When successful, you should see:
+```
+✅ Linear ticket created successfully!
+Title: create test ticket
+ID: [ticket-id]
+URL: https://linear.app/[workspace]/issue/[ticket-key]
+```
+
+## Troubleshooting
+
+1. **API Key Issues**: Make sure your Linear API key is valid and has the necessary permissions
+2. **MCP Server Issues**: If the MCP server fails, the script will fall back to direct API calls
+3. **Network Issues**: Ensure you have internet connectivity to reach Linear's API
+
+## Integration with Continue
+
+This setup enables the Continue AI assistant to create Linear tickets using the MCP protocol, providing a standardized way to interact with Linear's issue tracking system.
