`filesystemwatcher-mcp` lets your AI coding agent (Gemini, Claude, Cursor, Copilot, etc.)
watch directories for live file-system changes. It acts as a
[Model Context Protocol](https://modelcontextprotocol.io/) (MCP) server, giving your
agent event-driven access to file creations, modifications, deletions, and moves —
without busy-polling.

## Key features

- **Event-driven file watching**: Uses [Watchdog](https://github.com/gorakhargosh/watchdog) for cross-platform native OS events (`inotify`, `FSEvents`, `ReadDirectoryChangesW`).
- **Safe by design**: Blocks watching system-critical paths on Windows, macOS, and Linux. Strict path guardrails are enforced server-side.
- **Flexible filtering**: Filter events by file extension, glob pattern, or event type (`created`, `modified`, `deleted`, `moved`).
- **Debounced events**: Rapid successive events on the same file are coalesced over a 500 ms window — no duplicate noise.
- **Consume-once semantics**: `poll_events` drains the queue, making it easy to integrate into agent loops.
- **Explicit error surfacing**: All failure modes (permission denied, OS backend crash, watch limit) return structured `{"success": false, "error": "..."}` responses rather than crashing silently.

## Requirements

- [Python](https://www.python.org/) 3.10 or newer.
- [uv](https://docs.astral.sh/uv/) (recommended) or `pip`.

## Getting started

Add the following config to your MCP client:

```json
{
  "mcpServers": {
    "filesystemwatcher": {
