…ClientTransport Added migration guide for users who were using the deprecated transport classes directly. These classes have been replaced by the official MCP SDK transport classes which now work natively with Cloudflare Workers. Changes: - Add deprecation notice for SSEEdgeClientTransport and StreamableHTTPEdgeClientTransport - Provide before/after code examples showing import path migration - Explain that the official SDK classes now support Workers natively Related to cloudflare/agents#637 Generated with Claude Code Co-Authored-By: Claude <[email protected]>

Document the deprecation of SSEEdgeClientTransport and StreamableHTTPEdgeClientTransport in favor of standard MCP SDK transports. Since workerd now supports the duplex parameter, the custom edge transports are no longer necessary. Users should migrate to SSEClientTransport and StreamableHTTPClientTransport from @modelcontextprotocol/sdk. Related to cloudflare/agents#637

Summary
Documents the deprecation of
SSEEdgeClientTransportandStreamableHTTPEdgeClientTransportclasses and provides migration guidance for users.Changes
Context
Related to cloudflare/agents#637 - This PR removed the custom edge transport implementations since the official MCP TypeScript SDK now supports Cloudflare Workers natively (as of summer 2024). The SDK now exports deprecated wrapper classes that log console warnings to guide users to update their imports.
Target Audience
Users who were directly importing and using these transport classes in custom MCP client implementations (advanced use case - most users rely on the automatic transport handling in
McpAgentandaddMcpServer()).Generated with Claude Code
