# filesystem

# `fastmcp.server.providers.filesystem`

FileSystemProvider for filesystem-based component discovery.

FileSystemProvider scans a directory for Python files, imports them, and
registers any Tool, Resource, ResourceTemplate, or Prompt objects found.

Components are created using the standalone decorators from fastmcp.tools,
fastmcp.resources, and fastmcp.prompts:

Example:

```python theme={null}
# In mcp/tools.py
from fastmcp.tools import tool

@tool
def greet(name: str) -> str:
    return f"Hello, {name}!"

# In main.py
from pathlib import Path

from fastmcp import FastMCP
from fastmcp.server.providers import FileSystemProvider

mcp = FastMCP("MyServer", providers=[FileSystemProvider(Path(__file__).parent / "mcp")])
```

Provider that discovers components from the filesystem.

Scans a directory for Python files and registers any Tool, Resource,
ResourceTemplate, or Prompt objects found. Components are created using
the standalone decorators:

* @tool from fastmcp.tools
* @resource from fastmcp.resources
* @prompt from fastmcp.prompts

**Args:**

* `root`: Root directory to scan. Defaults to current directory.
* `reload`: If True, re-scan files on every request (dev mode).
  Defaults to False (scan once at init, cache results).
