Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://preflight.abacore.net/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.abacore-net. Endpoint host: preflight.abacore.net. ARD identifier: urn:air:io.github.abacore-net:mcp:acn-preflight.
First indexed 21 September 2026. The tools are exactly what the server returned; nothing on this page
