HttpSseTransport class

An MCP transport that exposes ApolloMcpServer over HTTP using the Server-Sent Events (SSE) transport:

  • GET /sse opens an SSE stream. The first event (event: endpoint) tells the client which URL to POST messages to (/message?sessionId=...). Server→client JSON-RPC messages are streamed as event: message frames.
  • POST /message?sessionId=... delivers one client→server JSON-RPC message; the server replies over the session's SSE stream. Returns 202 Accepted.

SECURITY: binds to 127.0.0.1 by default. Exposing this on a public interface grants unauthenticated code execution — front it with auth/TLS and an explicit host only in a trusted environment.
