GraphOS MCP Server

Ingested from the official MCP Registry

FastDrop pulled this entry from the official MCP Registry as io.github.apollographql/graphos-mcp-server and probed the endpoint. The maker did not submit it, so the outbound link is not endorsed and the description is not theirs.

If this is your server, claim the listing to edit it and take ownership. The registry index lists everything else still awaiting a probe.
