The full toolkit for agent workflows

Agents get their own workspaces to collaborate with your team, with built-in search, sharing, and AI.

API

org_manage

Create project-scoped workspaces on demand. Intelligence mode auto-indexes files for RAG.

Files + Folders

storage, storage_manage

CRUD, move, copy, versions, locks, previews for 10+ formats. Chunked uploads up to 100 GB per file, by plan.

Import

upload_manage

Import files from any URL. OAuth support for Google Drive, OneDrive, Box, Dropbox. No local I/O.

Semantic Search

storage action=search

Find files by meaning, not keywords. "Show me contracts with indemnity clauses" works.

AI Chat (RAG)

ai_manage action=ask

Ask questions across entire workspaces. Auto-summarization, citations, metadata extraction.

MCP Server

mcp.fast.io

Consolidated tools via Streamable HTTP. Session state persisted in Durable Objects.

Activity Feed

event, event_manage

Search the audit log, summarize recent activity with AI, and long-poll for changes instead of polling in a tight loop.

Ownership Transfer

org_manage action=transfer-ownership

Build for humans, then hand off. Agent keeps admin access after transfer.

Shares & Content Portals

share_manage

Three modes: Send (deliver), Receive (collect), Exchange (collaborate). Password protection, expiration, branding.

Comments & Annotations

comment, comment_manage

Region-anchored feedback on images, timestamps on video/audio, page-specific on PDFs. Threaded replies.

Use Cases

Powering every type of agent: from browser automation to file delivery, Fastio enables any agent to store and share.

Python / MCP
# Upload a file the agent staged at POST /blob
upload = await mcp.call(
    "upload_manage",
    {
        "action": "stream-upload",
        "profile_type": "workspace",
        "profile_id": WORKSPACE_ID,
        "parent_node_id": RECEIPTS_FOLDER_ID,
        "filename": "order-confirmation.png",
        "blob_id": blob_id
    }
)
# Or import directly from a URL
job = await mcp.call(
    "upload_manage",
    {
        "action": "web-import",
        "profile_type": "workspace",
        "profile_id": WORKSPACE_ID,
        "parent_node_id": RECEIPTS_FOLDER_ID,
        "url": "https://example.com/receipt.pdf"
    }
)

Connect via MCP, CLI, or REST API

Add Fastio to any MCP-compatible client, use the CLI for direct shell access, or call the REST API from any language. 

https://mcp.fast.io/mcp/tools

For ChatGPT and Codex, install the Fastio plugin, and in Grok Bot, add the Fastio plugin. The ChatGPT tab is the custom MCP server address for either one. In Claude, add the URL as a custom connector under Customize, then Connectors. Steps for other clients are at mcp.fast.io/docs (opens in a new tab)

FAQ

What makes Fastio different from Drive/Dropbox for agents?

Built-in MCP server with a consolidated set of MCP tools. AI intelligence auto-indexes files for RAG queries. Ownership transfer lets agents build, then hand off to humans.

How do you scope an agent to a single workspace?

Create a workspace per task. Workspace-scoped tokens limit access to that workspace only. Agent retains admin after ownership transfer.

Do you support large files and streaming downloads?

Up to 25 GB per file on Starter, 50 GB on Business, and 100 GB on Enterprise. HLS adaptive streaming with 4K HEVC (H.265) encoding for video, 50-60% faster than raw. Chunked uploads with resume support.

How does the AI/RAG feature work?

Enable "intelligence" on a workspace. Files are auto-indexed, summarized, and queryable with the ai_manage tool (action ask). Answers include citations to specific pages.

What's the ownership transfer flow?

Agent creates a workspace collection → builds workspaces and shares → calls org_manage with action transfer-ownership → human claims via link → agent keeps admin access.

What audit logs do you provide?

Full event log through the event tool. AI-powered summaries through event_manage. Track uploads, downloads, shares, access by identity.

Is there a free trial?

Yes. Fastio starts with a 14-day Business Trial. You can test real workspaces, portals, file AI, and agent connections before choosing Starter, Business, or Enterprise.
