Tools & capabilities
Filesystem MCP tools 13
list_rootsList allowed workspace roots. Call this first — all other tools scope to these.listList directory contents. Returns entries (dirs-first, alphabetical) and an ASCII tree.find_filesFind files by glob pattern (e.g. `**/*.ts`). Returns matching files with metadata.statGet file/directory metadata: size, modified time, permissions, MIME type, token estimate.search_textSearch file contents for text (grep-like). Returns matching lines with context.diffCompare two files and return a unified diff with added/removed line counts.readRead a text file. Supports head/tail and line ranges. Accepts `paths[]` for batches.createCreate one or more files, creating parent directories as needed. An existing file prompts the user to confirm the overwrite; `overwrite: true` on an entry skips the prompt, `append: true` adds to the end instead.editApply sequential literal string replacements to one or more files (up to 5 files per call, 100 edits per file).moveMove, rename, or copy (`copy: true`) one or more files/directories to explicit destinations.deletePermanently delete one or more files or directories. This action is irreversible.replace_textBulk search-and-replace across files matching a glob pattern.- +1 more on the listing page
