OnlyWorlds MCP Client (DEPRECATED)
This package is deprecated. The OnlyWorlds MCP server is now hosted directly at https://www.onlyworlds.com/mcp (streamable HTTP) -- no local bridge needed.
Connect instead
Claude Code:
claude mcp add --transport http onlyworlds https://www.onlyworlds.com/mcp \
--header "API-Key: <your world key>" --header "API-Pin: <your seat secret>"
Claude Desktop and any streamable-HTTP MCP client: use the same URL and headers. Stdio-only clients can use the community mcp-remote shim with that URL.
The hosted server exposes 12 tools: schema lookups need no key; element reads and writes use your world key. For writes, give the agent its own agent seat: its secret goes where a PIN goes, works in one world, and can be removed without touching your account PIN. Get a key at onlyworlds.com; docs at onlyworlds.github.io.
Why deprecated
This package bridged stdio clients to an old endpoint (/mcp/messages/) that was retired when the hosted MCP server launched (2026-07-12). That endpoint now returns only a moved-notice, so the bridge cannot serve data. The final version (1.1.2) answers every request with the migration message above instead of failing silently.
