import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js";

const client = new Client({
  name: 'jira-test-client',
  version: '1.0.0'
});

const transport = new StreamableHTTPClientTransport(
  new URL('http://localhost:3000/mcp')
);

await client.connect(transport);

// Test connection
const connectionInfo = await client.callTool('jira_get_connection_info', {});
console.log('Connection:', connectionInfo);

// Search for issues
const issues = await client.callTool('jira_search_issues', {
  projectKey: 'PROJ',
  maxResults: 10
});
console.log('Issues:', issues);

// Create an issue
const newIssue = await client.callTool('jira_create_issue', {
  projectKey: 'PROJ',

🐛 Troubleshooting

Common Issues

1. Authentication Failed

• Verify your API token is correct
• Check that your email matches your Jira account
• Ensure JIRA_BASE_URL doesn't have a trailing slash

1. Permission Denied

• Verify you have the required Jira permissions
• Check project access rights
• Ensure issue type is available in the project

1. Connection Issues

• Verify JIRA_BASE_URL is accessible
• Check firewall/network restrictions
• Test connection with /health endpoint

1. Tool Errors

• Check the MCP tool response for detailed error messages
• Verify input parameters match the expected schema
• Use jira_get_connection_info to test basic connectivity
