Extract MCPServer.handle_request(dict) from _handle_raw so the stdio loop and an HTTP transport can share one JSON-RPC dispatch source. Echo the client's requested protocolVersion in initialize (honours both 2024-11-05 stdio and 2025-03-26 Streamable HTTP handshakes).
…r auth - New opencrab/mcp/http_app.py: shared FastAPI mcp_router (POST /mcp dispatch via MCPServer.handle_request, GET 405, DELETE 200) + lightweight create_app. Optional Bearer auth (HMAC compare); token from --auth-token/--auth-token-file or OPENCRAB_MCP_TOKEN(_FILE). Stateless, single worker. - opencrab serve gains --transport [stdio|http], --host, --port, --auth-token, --auth-token-file. stdio stays the default. No new deps (fastapi/uvicorn are already required). - config: MCP_HTTP_HOST (127.0.0.1) / MCP_HTTP_PORT (8765).
README HTTP-transport section, MCP_HTTP_HOST/PORT in .env.example, serve-http Makefile target.

opencrab serve는 현재 stdio MCP만 제공합니다. 원격/HTTP로 붙이려면supergateway같은 외부 stdio→HTTP 브리지가 필요했습니다. 이 PR은 serve가 직접 Streamable HTTP(2025-03-26) MCP transport를 제공하게 해서 외부 브리지를 불필요하게 만듭니다. stdio는 기본값으로 그대로 유지됩니다(하위호환).변경
opencrab/mcp/server.py—_handle_raw에서handle_request(dict)를 추출해 stdio·HTTP가 JSON-RPC 디스패치를 단일 출처로 공유.initialize가 클라이언트의protocolVersion을 에코(2024-11-05 stdio / 2025-03-26 HTTP 핸드셰이크 모두 수용).opencrab/mcp/http_app.py(신규) — 공유 FastAPImcp_router(POST/mcp→handle_request위임, GET 405, DELETE 200, notification→202, 배치 지원) + 경량create_app. 선택적 Bearer 인증(HMAC compare): 토큰이--auth-token/--auth-token-file또는OPENCRAB_MCP_TOKEN(_FILE)로 주어질 때만 활성, 미설정 시 무인증.opencrab/cli.py—serve --transport [stdio|http] --host --port --auth-token --auth-token-file. http는uvicorn단일 워커(chroma PersistentClient 단일 프로세스 제약).opencrab/config.py—MCP_HTTP_HOST(127.0.0.1) /MCP_HTTP_PORT(8765). 토큰은 config에 저장 안 함..env.example,Makefile serve-http.stateless 설계: 각 POST가 독립 요청/응답(Mcp-Session-Id·서버 푸시 SSE 없음). 모든 툴이 요청-응답형이라 충분. 새 의존성 0(fastapi/uvicorn 이미 필수).
