salesforce-mcp-tunnel-drop-container-healthy-pattern
Salesforce MCP tunnel can drop connections repeatedly while the underlying container reports healthy (HTTP 200 on health endpoint). When MCP tools fail consistently but docker ps shows the container running, switch to direct Streamable HTTP bypass: POST /mcp to initialize session, capture Mcp-Session-Id header, then use it for subsequent tool calls. This is a tunnel-layer issue, not a server issue.
