This PR adds an MCP (Model Context Protocol ) server to LLDB. For motivation and background, please refer to the corresponding RFC: https://discourse.llvm.org/t/rfc-adding-mcp-support-to-lldb/86798 I implemented this as a new kind of plugin. The idea is that we could support multiple protocol servers (e.g. if we want to support DAP from within LLDB). This also introduces a corresponding top-level command (`protocol-server`) with two subcommands to `start` and `stop` the server. ``` (lldb) protocol-server start MCP tcp://localhost:1234 MCP server started with connection listeners: connection://[::1]:1234, connection://[127.0.0.1]:1234 ``` The MCP sever supports one tool (`lldb_command`) which executes a command, but can easily be extended with more commands.
