How the receive_full_response Method Handles Chunked Responses from Blender

April 13, 2026 ahujasid/blender-mcp ↗

The receive_full_response method in src/blender_mcp/server.py accumulates TCP socket chunks in a buffer, attempting to parse the concatenated bytes as JSON after each read to detect when the complete Blender response has arrived.

When communicating with the Blender add-on via TCP, large JSON payloads may arrive fragmented across multiple network packets. The receive_full_response method in the ahujasid/blender-mcp repository implements a robust reassembly strategy that guarantees complete message delivery before returning control to the caller.
