From f378dc9d6b8f74d34b4dfd3b65cf564c689bdb95 Mon Sep 17 00:00:00 2001 From: Mike Date: Fri, 23 Oct 2026 09:49:49 -0400 Subject: Add a loopback MCP server for the running viewer (#44) The server is off by default and listens on 127.0.0.1. It can see and act in the logged-in session, including inventory, object contents, script editing, mesh and material upload, and animated mesh. --- indra/newview/CMakeLists.txt | 1 + indra/newview/app_settings/settings.xml | 22 + indra/newview/llappviewer.cpp | 3 + indra/newview/llfloaterimnearbychat.cpp | 2 + indra/newview/llfloatermodelpreview.cpp | 183 ++ indra/newview/llfloatermodelpreview.h | 20 + indra/newview/llfloaterscriptdebug.cpp | 3 + indra/newview/llimview.cpp | 2 + indra/newview/llmaterialeditor.cpp | 127 +- indra/newview/llmaterialeditor.h | 11 + indra/newview/llmodelpreview.cpp | 22 + indra/newview/llpreviewscript.cpp | 23 + indra/newview/llpreviewscript.h | 5 + indra/newview/llviewermcp.cpp | 3442 +++++++++++++++++++++++++++++++ indra/newview/llviewermcp.h | 33 + 15 files changed, 3898 insertions(+), 1 deletion(-) create mode 100644 indra/newview/llviewermcp.cpp create mode 100644 indra/newview/llviewermcp.h diff --git a/indra/newview/CMakeLists.txt b/indra/newview/CMakeLists.txt index 8d65e4b026..3df9b36694 100644 --- a/indra/newview/CMakeLists.txt +++ b/indra/newview/CMakeLists.txt @@ -710,6 +710,7 @@ set(viewer_SOURCE_FILES llviewermedia_streamingaudio.cpp llviewermediafocus.cpp llviewermenu.cpp + llviewermcp.cpp llviewermenufile.cpp llviewermessage.cpp llviewernetwork.cpp diff --git a/indra/newview/app_settings/settings.xml b/indra/newview/app_settings/settings.xml index 7d7cb110ec..22c5fa8b2d 100644 --- a/indra/newview/app_settings/settings.xml +++ b/indra/newview/app_settings/settings.xml @@ -2994,6 +2994,28 @@ Value 0 + EnableViewerMCP + + Comment + Listen on 127.0.0.1 for an MCP client that can see and act as this logged-in viewer.
