Disk

The Disk resource mounts a local directory at some prefix such as /data/. All operations are backed by real files on disk. Path resolution validates against the root boundary to prevent directory traversal escapes.

Config

from mirage import MountMode, Workspace
from mirage.resource.disk import DiskResource

resource = DiskResource(root="/path/to/dir")
ws = Workspace({"/data": resource}, mode=MountMode.READ)

DiskResource(root=...) takes a single root path argument pointing to the directory to mount. Both READ and WRITE modes are supported.

Filesystem Layout

The Disk resource mirrors the structure of the root directory. For example, if root="/srv/files" contains:

/srv/files/
  notes.txt
  config.json
  reports/
    q1.csv
    q2.csv

Then mounting at /data/ exposes:

/data/
  notes.txt
  config.json
  reports/
    q1.csv
    q2.csv

Paths like ../../etc/passwd are rejected - resolution is always confined to the root boundary.

Cache

The Disk resource uses IndexCacheStore with index_ttl = 60 (1 minute). Directory listings are cached for up to 60 seconds before being refreshed from disk.

Example

import asyncio
import shutil
import tempfile
from pathlib import Path

from mirage import MountMode, Workspace
from mirage.resource.disk import DiskResource

DATA_DIR = Path("/path/to/files")

tmp = tempfile.mkdtemp()
shutil.copytree(DATA_DIR, Path(tmp) / "files", dirs_exist_ok=True)

resource = DiskResource(root=tmp + "/files")


async def main() -> None:
    ws = Workspace({"/data/": resource}, mode=MountMode.READ)

    r = await ws.execute("ls /data/")
    print(await r.stdout_str())

    r = await ws.execute("cat /data/example.json")
    print(await r.stdout_str())

    r = await ws.execute("tree /data/")
    print(await r.stdout_str())

    r = await ws.execute("find /data/ -name '*.json'")
    print(await r.stdout_str())

    r = await ws.execute("grep example /data/example.json")
    print(await r.stdout_str())

    r = await ws.execute("stat /data/example.json")
    print(await r.stdout_str())


if __name__ == "__main__":
    asyncio.run(main())

Shell Commands

Data Format Support

Commands with format-specific variants for structured data files:

Format	Extension	Variants
Parquet	`.parquet`	cat, head, tail, wc, stat, cut, grep, ls, file
Feather	`.feather`	cat, head, tail, wc, stat, cut, grep, ls, file
ORC	`.orc`	cat, head, tail, wc, stat, cut, grep, ls, file
HDF5	`.hdf5`	cat, head, tail, wc, stat, cut, grep, ls, file

These variants auto-detect the format by extension and convert to tabular text (CSV) for processing.

Use Cases

Local directory access: Mount local directories for AI agents to read and process
Sandboxed file access: Restrict agent file operations to a specific directory tree
FUSE mounting: Expose disk files through a virtual FUSE mount for external tools
Data pipelines: Process local datasets with shell-like commands
Development: Test file operations against real data before deploying to cloud resources
