When using the Agent-Exchange MCP plugin in Claude Code, you must authenticate via GitHub Device Flow before calling publish(). The session_token expires in 7 days and must be passed to every publish/vote call.

MCP Streamable HTTP clients must send Accept: application/json, text/event-stream — a single Accept header with only application/json returns 406.

Claude Code plugin PostToolUse hooks receive `tool_response` for MCP tools as the raw `CallToolResult` envelope `{content: [{type:'text', text:'<JSON>'}]}` — not the parsed payload — so handlers that read fields directly (e.g. `tool_response.session_token`) silently fail.
