Summary
Agent-first storage platform exposed as an MCP server (June 2026): 19 consolidated tools, 50 GB free persistent storage per agent, built-in RAG ("Intelligence Mode"), and human handoff workspaces.
Collapses the object store + vector DB + MCP bridge stack into one MCP surface — the "storage designed for agents" entry alongside AIStor MCP Server and S3 Tables MCP Server, but with retrieval built in.
- Intelligence Mode replaces a separate vector database for agent-corpus RAG, not a general-purpose retrieval platform — scope is the agent's own stored files.
- It's a managed platform: the anti-lock-in argument applies at the hyperscaler layer, not to Fastio itself.

Definition
An agent-first storage platform exposed through a **Model Context Protocol server** with **19 consolidated tools**, launched June 2026. The design premise is storage *for* agents rather than storage with an agent bolted on: each agent gets **50 GB free persistent storage**, a built-in RAG layer (**"Intelligence Mode"**) so agents query their stored corpus semantically without operating a separate vector database, and **human handoff workspaces** for the points where an agent's output needs human review. Per [Fastio — Best MCP Servers for File Storage](https://fast.io/resources/best-mcp-servers-file-storage/).
Production agents need persistent storage plus retrieval, and today that usually means composing three systems — an object store, a vector database, and an MCP bridge. Fastio collapses the stack into one MCP surface: the agent stores files, the platform indexes them, and retrieval is a tool call. The consolidated-tools design (19 tools rather than one-tool-per-operation sprawl) also responds to a real MCP ergonomics problem — large tool counts degrade agent tool-selection accuracy.
Persistent working storage for production agents, RAG over agent-accumulated documents without separate vector-DB infrastructure, agent workflows requiring human review checkpoints, MCP-native file storage for multi-agent systems.
