Troubleshooting

Server not connecting

• Verify the absolute path in your configuration

• Ensure the server is built (npm run build)

• Check that environment variables are set correctly

• Restart Claude Desktop or VS Code after configuration changes

Authentication errors

• Verify your Personal Access Token is still valid

• Check that the token has not expired

• Ensure the token has appropriate permissions

• Verify the JIRA_BASE_URL is correct (no trailing slash)

API errors

• Check Jira server logs for detailed error messages

• Verify the Jira API is accessible from your machine

• Ensure your user account has necessary permissions

• Try accessing the REST API directly: https://jira.domain.com/rest/api/2/myself

Common issues

• "Cannot find module": Run npm install and npm run build

• "Connection refused": Check if Jira server is accessible and URL is correct

• "Unauthorized": Verify your Personal Access Token

• "Issue type not found": Use jira_get_issue_types to see valid types for the project

Security Best Practices

1. Never commit your Personal Access Token to version control

2. Store tokens securely in configuration files with restricted permissions

3. Use tokens with minimal required permissions

4. Set expiration dates for tokens

5. Rotate tokens regularly

6. Monitor token usage in Jira's audit logs
