Mirage is a Unified Virtual File System for AI Agents: it mounts services and data sources like S3, Google Drive, Slack, Gmail, and Redis side-by-side as one filesystem. Any LLM that already knows bash can read, grep, and pipe across every backend out of the box, with zero new vocabulary.

const ws = new Workspace({
  '/data':  new RAMResource(),
  '/s3':    new S3Resource({ bucket: 'logs' }),
  '/slack': new SlackResource({ token: process.env.SLACKBOTTOKEN! }),
})
await ws.execute('grep -r alert /slack/channels/general__C04QX/ | wc -l') await ws.execute('cp /s3/report.csv /data/local.csv') await ws.execute('wc -l $(find /s3/data -name "*.jsonl")')
// Commands are extensible: register new commands, or override one per // resource + filetype, e.g. cat on S3 Parquet renders rows as JSON. ws.command('summarize', ...) ws.command('cat', { resource: 's3', filetype: 'parquet' }, ...)
await ws.execute('summarize /data/local.csv') await ws.execute('cat /s3/events/2026-05-06.parquet | jq .user')

About

• One interface instead of N SDKs and M MCPs. Every service speaks the same filesystem semantics, and pipelines compose across services as naturally as on a local disk.
• Around 50 built-in backends: RAM, Disk, Redis, S3 / R2 / OCI / Supabase / GCS, Gmail / GDrive / GDocs / GSheets / GSlides, GitHub / Linear / Notion / Trello, Slack / Discord / Email, MongoDB / Postgres / LanceDB / Qdrant, SSH, and more, mounted side-by-side under a single root.
• Portable workspaces: clone, snapshot, and version a workspace; agent runs move between machines without restarting or reconfiguring the system.
• Embeddable: the Python and TypeScript SDKs run in-process inside FastAPI, Express, browser apps, or any async runtime; no separate process required.
• Agent integrations: OpenAI Agents SDK, Vercel AI SDK, LangChain, Pydantic AI, CAMEL, and OpenHands via the SDKs; coding agents like Claude Code and Codex via the lightweight CLI + daemon.

Architecture

Installation

• Python ≥ 3.11 for the mirage-ai package and the mirage CLI
• Node.js ≥ 20 for the TypeScript SDK
• macOS or Linux (FUSE-based mounts require platform support)

Python

uv add mirage-ai    # installs the mirage library and the mirage CLI binary

TypeScript

npm install @struktoai/mirage-node      # Node.js servers and CLIs
npm install @struktoai/mirage-browser   # browser / edge runtimes
npm install @struktoai/mirage-agents    # OpenAI / Vercel AI / LangChain / Mastra adapters

Both runtime packages pull in @struktoai/mirage-core automatically.

CLI

curl -fsSL https://strukto.ai/mirage/install.sh | sh
or
npm install -g @struktoai/mirage-cli
or
uvx mirage-ai
or
npx @struktoai/mirage-cli

Quickstart

Python

from mirage import Workspace
from mirage.resource.ram import RAMResource
from mirage.resource.s3 import S3Config, S3Resource
ws = Workspace({     "/data": RAMResource(),     "/s3":   S3Resource(S3Config(bucket="my-bucket")), })
await ws.execute("cp /s3/report.csv /data/report.csv") await ws.execute("grep alert /s3/data/log.jsonl | wc -l")
await ws.snapshot("demo.tar")

TypeScript

import { Workspace, RAMResource, S3Resource } from '@struktoai/mirage-node'
const ws = new Workspace({   '/data': new RAMResource(),   '/s3':   new S3Resource({ bucket: 'my-bucket' }), })
await ws.execute('cp /s3/report.csv /data/report.csv') await ws.execute('grep alert /s3/data/log.jsonl | wc -l')
await ws.snapshot('demo.tar')

CLI

mirage workspace create ws.yaml --id demo
mirage execute   --workspace_id demo --command "cp /s3/report.csv /data/report.csv"
mirage provision --workspace_id demo --command "cat /s3/data/large.jsonl"
mirage workspace snapshot demo demo.tar
mirage workspace load demo.tar --id demo-restored

Agent Frameworks

Mirage plugs into agent frameworks as a sandbox or tool layer. POSIX operations such as read can also be customized per resource and filetype, e.g. reading a PDF returns parsed pages instead of raw bytes.

Cache

Every Workspace has a two-layer cache so repeated work against remote backends hits local state instead of the network:

• Index cache: listings and metadata. The first directory walk hits the API; later ones serve from the index until the TTL expires (default 10 minutes).
• File cache: object bytes. The first read streams from origin; later pipelines read from cache (default 512 MB).

import { RedisFileCacheStore, S3Resource, Workspace } from '@struktoai/mirage-node'
const ws = new Workspace(   { '/s3': new S3Resource({ bucket: 'my-bucket' }) },   {     cache: new RedisFileCacheStore({ url: 'redis://localhost:6379/0', cacheLimit: '8GB' }),     index: { type: 'redis', url: 'redis://localhost:6379/0', ttl: 600 },   }, )

See the cache docs for the full miss/hit lifecycle.
