MCP tools

Tool	What it does
get_editor_state	Every open window: folder, main file, active file, view, tabs, unsaved changes, cursor, selection, live preview.
get_unsaved	The text of the active file, if it has unsaved changes.
get_diagnostics	Compile errors and warnings with file and line, and whether a compile is running.
get_compile_config	Compile command, format, engine, output folder, PDF and log paths.
open_file	Opens a file. With a line, in the source editor.
show_diff	The Diff view against the last commit, in a git repository.
set_view_mode	visual, source or diff.
synctex_to_line	Shows where a line appears in the PDF. For Typst, moves the live preview, which must be running.
set_main_file	Sets the main file (.tex or .typ). Without path, clears it.
compile	Starts a compile and returns at once. Poll get_diagnostics until it finishes.
set_output_paths	Changes the output folder, PDF path or log path. An empty string clears one.
get_comments	Comment threads with the line each sits on. A thread whose text cannot be found reads as detached.
add_comment	Adds a thread on a quote that appears exactly once in the file.
reply_to_comment	Replies to a thread.
resolve_comment	Resolves a thread. resolved: false reopens it.
reanchor_comment	Moves a thread onto new text.
suggest_edit	Puts a change into the open file as a suggestion.

Comment tools take by, the author name, default "AI assistant". prefix, suffix and line pick between copies of a quote.

suggest_edit is refused when the file is not the one open in the editor, the quote does not match exactly once (markup included), the replacement equals the quote, or you host a shared session. In LaTeX it is also refused if the new text cites a key your bibliography lacks or removes a \label.
