`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:

# 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")])

Classes

`FileSystemProvider`

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).
