Xcode: MCP Bridge Wrapper for Cursor
If you're trying to use Xcode 26.3's MCP bridge with Cursor and hitting spec compliance errors, this wrapper is the fix. Apple's mcpbridge returns tool responses in the content field but skips the required structuredContent field when outputSchema is declared. Claude and Codex have workarounds baked in, but Cursor strictly follows the MCP spec and rejects the responses. This Python wrapper sits between your client and mcpbridge, intercepts the non-compliant responses, and copies content into structuredContent so everything works. It also includes a broker mode that maintains one persistent upstream session to reduce reconnection overhead, which helps with the repeated connection dialogs documented in Xcode 26.4 release notes.

Xcode MCP Bridge Wrapper
mcpbridge-wrapper connects external MCP clients to Xcode through Apple's
xcrun mcpbridge. It repairs Xcode tool responses that declare an
outputSchema but omit structuredContent. The repair works in both direct
and broker modes. Broker mode also lets several clients share one persistent
Xcode connection, reducing repeated connection prompts.
