Fastio gives your team and AI agents a workspace for each project, bringing source files, comments and new work together. Connect a compatible MCP client to find files, answer questions from project material, and save results where the team can review and use them. Sign in through Fastio and choose the workspaces the connection can reach. Read Only connections expose read tools; Read & Write connections also allow changes. - **Files and folders:** browse, read, upload, and organize files, with version history and trash. - **Search:** find files by keyword; search file content and meaning when Deep Indexing is enabled and files have been processed. - **Metadata:** read, set, and search metadata fields, including extracted fields where available. - **Shares** create and manage shares for sending or collecting files. - **Comments and members:** read and add comments, and manage workspace membership within your permissions. - **Activity:** search workspace events to see what changed. Hosted by Fastio, with no server installation required. - Claude and most MCP clients: https://mcp.fast.io/mcp/tools - ChatGPT: https://mcp.fast.io/mcp/operations - ChatGPT and Codex: Fastio plugin - Claude Code, Cursor and similar coding agents: https://mcp.fast.io/mcp/code - Setup and client-specific capabilities: https://mcp.fast.io/docs Paid plans.

MCP readiness
Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 70.0/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ
| Valid MCP handshake | 10/10 | initialize and tools/list both answered. |
| Live MCP endpoint | 24/25 | Endpoint answers the MCP initialize handshake (3264 ms); slow response -1. |
| Protocol revision | 8/10 | Speaks MCP 2025-11-25, 1 revision(s) behind 2026-07-28. |
| Signed descriptor | n/a | No MCP standard defines a signed server descriptor. |
| Uptime (30 days) | 15/15 | 30/30 probes succeeded over 30 days (100%). |
| Tool declaration | 10/10 | Lists 37 tool(s) with descriptions. |
| Verified identity | 5/10 | Publisher declared (repository, package or homepage); claim this listing to verify domain control. |
| Freshness + modern flags | 4/5 | seen in a source within 7 days. |
| Auth declaration | 2/5 | Declares credential scheme: smithery_api_key. |
