Add sse mcp support

[aheizi]

Context

The previous issue was #1495

this Pr resolved the issue where mcp does not display in certain situations.

Implementation

The previous problem was：In the initializeMcpServers method, it directly reads the configuration file and passes config.mcpServers to the updateServerConnections method without validation. However, the connectToServer method expects a configuration object that has already been validated by ServerConfigSchema.

Now this issue has been resolved in this commit: e2182eb

  • Enhances error handling with showErrorMessage() in McpHub.ts.
• Configuration:
  • Introduces ServerConfigSchema to validate server configurations for both stdio and SSE types.
  • Validates configurations in validateServerConfig() in McpHub.ts.
• Testing:
  • Updates tests in McpHub.test.ts to cover new SSE functionality and configuration validation.
  • Tests toggleToolAlwaysAllow() and updateServerTimeout() for correct behavior.

The pull request is quite large, with 10 files changed and over 1000 lines added. It includes various changes such as adding new dependencies, updating configurations, and introducing SSE support for MCP.

To improve manageability and review efficiency, consider splitting the pull request into smaller, focused ones. Here are some suggestions:

1. Dependency Updates: Create a separate pull request for updating dependencies in package.json and adding the alias plugin in esbuild.js.

2. SSE Support: Group all changes related to SSE support, including the new SSEClientTransport class and updates in McpHub.ts, into a dedicated pull request.

3. Documentation Updates: Separate the documentation changes in system.test.ts.snap and mcp-servers.ts into their own pull request.

4. Timezone Fixes: Consider isolating the timezone offset formatting fix in Cline.ts into a separate pull request.

These splits will help streamline the review process and ensure each set of changes is thoroughly evaluated. Let me know if you have any questions or need further clarification.
