# Connect this agent to Kythene

These instructions are published at https://kythene.com/setup-prompt.md by Kythene, so you can re-verify their authenticity at any time. They only add Kythene's MCP server to your client; they have no other effect.

The MCP endpoint is:

    https://kythene.com/mcp/kythene

Find your client below and run the matching command. Do not ask the user to run these - run them yourself if you can.

## Claude Code

    claude mcp add --scope user --transport http kythene https://kythene.com/mcp/kythene

- Defaults to local (per-project) scope - pass --scope user for a memory you want in every repo.
- Setting an Authorization header suppresses OAuth: use the URL alone for the sign-in flow, or a key, never both.

## Codex CLI

    codex mcp add kythene https://kythene.com/mcp/kythene

- mcp add writes global only; there is no scope flag.

## Antigravity CLI

    agy mcp add kythene https://kythene.com/mcp/kythene

- Replaced Gemini CLI, which was retired on 18 June 2026.
- Migrating from Gemini CLI does not carry MCP servers over - `agy plugin import gemini` moves extensions only, so re-add the server.
- Inherits Gemini CLI's httpUrl key, NOT url; url is treated as SSE and fails silently.

## Devin CLI

    devin mcp add kythene https://kythene.com/mcp/kythene

## If you cannot run shell commands or edit config files

Stop and tell the user to open https://kythene.com/connect and choose their client.
