MCP SSE Bridge

Example Use Cases

• 1

  Connect Roo-Code to MCP servers that expose Server-Sent Events (SSE) but do not natively support stdin/stdout communication.

• 2

  A lightweight bridge to translate Roo stdin/stdout messages into HTTP/SSE requests and relay server responses back to Roo.

• 3

  An easy local integration or testing setup for MCP servers within Roo-Code workflows (including Windows and Linux setups via cline_mcp_settings.json).

Description

This utility connects Roo-Code (which communicates over stdin/stdout) to MCP servers that expose Server-Sent Events (SSE) over HTTP. It listens on the server's /sse endpoint for incoming events and forwards Roo messages to the server's HTTP endpoints (e.g., /messages/), relaying responses back to Roo via stdout. The tool is lightweight and intended for easy integration with Roo-Code via cline_mcp_settings.json, requiring only the server URL to run. It also includes basic troubleshooting guidance for connectivity issues.
