Setup complexity: low.

clawhub skill install kn74d15nyw6rzrc3fekbs5333d80ha0y:fast-io
  1. Install using `clawhub skill install kn74d15nyw6rzrc3fekbs5333d80ha0y:fast-io` in an isolated environment before connecting it to live workloads.
  2. No published capability contract is available yet, so validate auth and request/response behavior manually.
  3. Review the upstream CLAWHUB listing at https://clawhub.ai/dbalve/fast-io before using production credentials.

  Workspaces for agentic teams. Complete agent guide with all 19 consolidated
  tools using action-based routing — parameters, workflows, ID formats, and
  constraints. Use this skill when agents need shared workspaces to collaborate
  with other agents and humans, create branded shares (Send/Receive/Exchange),
  or query documents using built-in AI. Supports ownership transfer to humans,
  workspace management, workflow primitives (tasks, worklogs, approvals, todos),
  and real-time collaboration.
  Free agent plan with 50 GB storage and 5,000 monthly credits.

  Requires network access. Connects to the Fast.io MCP server at mcp.fast.io
  via Streamable HTTP (/mcp) or SSE (/sse).

# Fast.io MCP Server -- AI Agent Guide

**Version:** 1.104
**Last Updated:** 2026-02-26

The definitive guide for AI agents using the Fast.io MCP server. Covers why and how to use the platform: product capabilities, the free agent plan, authentication, core concepts (workspaces, shares, intelligence, previews, comments, URL import, metadata, workflow, ownership transfer), 12 end-to-end workflows, interactive MCP App widgets, and all 19 consolidated tools with action-based routing.

> **Versioned guide.** This guide is versioned and updated with each server release. The version number at the top of this document tracks tool parameters, ID formats, and API behavior changes. If you encounter unexpected errors, the guide version may have changed since you last read it.

> **Platform reference.** For a comprehensive overview of Fast.io's capabilities, the agent plan, key workflows, and upgrade paths, see [references/REFERENCE.md](references/REFERENCE.md).

## 1. Overview

**Workspaces for Agentic Teams. Collaborate, share, and query with AI -- all through one API, free.**

Fast.io provides workspaces for agentic teams -- where agents collaborate with other agents and with humans. Upload outputs, create branded data rooms, ask questions about documents using built-in AI, and hand everything off to a human when the job is done. No infrastructure to manage, no subscriptions to set up, no credit card required.

### The Problem Fast.io Solves

Agentic teams -- groups of agents working together and with humans -- need a shared place to work. Today, agents cobble together S3 buckets, presigned URLs, email attachments, and custom download pages. Every agent reinvents collaboration, and there is no shared workspace where agents and humans can see the same files, track activity, and hand off work.

When agents need to *understand* documents -- not just store them -- they have to download files, parse dozens of formats, build search indexes, and manage their own RAG pipeline. That is a lot of infrastructure for what should be a simple question: "What does this document say?"

# Fast.io for AI Agents

> **Version:** 1.25.0 | **Last updated:** 2026-02-21
>
> This guide is available at the `/current/agents/` endpoint on the connected API server.

**Workspaces for Agentic Teams. Collaborate, share, and query with AI — all through one API, free.**

Fast.io provides workspaces for agentic teams — where agents collaborate with other agents and with humans. Upload
outputs, create branded data rooms, ask questions about documents using built-in AI, and hand everything off to a human
when the job is done. No infrastructure to manage, no subscriptions to set up, no credit card required.

**MCP-enabled agents** should connect via the Model Context Protocol for the simplest integration — no raw HTTP calls
needed.

**Connection endpoints:**
- **Streamable HTTP (recommended):** `https://mcp.fast.io/mcp`
- **Legacy SSE:** `https://mcp.fast.io/sse`

The MCP server exposes **19 consolidated tools** using action-based routing — each tool covers a domain (e.g., `auth`,
`storage`, `upload`) and uses an `action` parameter to select the operation. See the "MCP Tool Architecture" section
below for the full tool list.

MCP-connected agents receive comprehensive workflow guidance through SERVER_INSTRUCTIONS at connection time, and can
read resources (`resources/read`) including `skill://guide` for full tool documentation, `session://status` for current
authentication state, and `download://` resource templates for direct file content retrieval.

This guide covers platform concepts and capabilities; the MCP server provides tool-level details through its standard
protocol interface. The API endpoints referenced below are what the MCP server calls under the hood, and are available
for agents that need direct HTTP access or capabilities not yet covered by the MCP tools.

## Why Agents Use Fast.io

### The Problem

Agentic teams — groups of agents working together and with humans — need a shared place to work. Today, agents cobble
together S3 buckets, presigned URLs, email attachments, and custom download pages. Every agent reinvents collaboration,
and there's no shared workspace where agents and humans can see the same files, track activity, and hand off work.

Meanwhile, when agents need to *understand* documents — not just store them — they have to download files, parse dozens
of formats, build search indexes, and manage their own RAG pipeline. That's a lot of infrastructure for what should be a
simple question: "What does this document say?"
