Our reading of SkyOS, from the data

SkyOS is a notes & knowledge MCP server, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

Maintenance is active: the last public signal was in the last day (2026-10-18). For comparison, 71% of notes & knowledge servers are active or maintained.

It runs as a hosted endpoint, so there is nothing to install.

Install SkyOS MCP server

claude mcp add --transport http ink-skyos-memory https://api.skyos.ink/mcp/chatgpt

{
  "mcpServers": {

    }
  }
}

{
