# Summation Sign-out

Auth lives in the host MCP client. Sign-out clears that session so the next Summation tool call re-prompts browser auth.

## Flow

1. **Disconnect** using the host control when available (Claude `/mcp` disconnect, or `codex mcp logout summation`). Prefer that over CLI remove when the host can do it.

2. **CLI fallback** only if the host control is unavailable. Do **not** blanket-suppress errors:

```bash
# Claude Code
claude mcp remove -s user summation
# Codex: logout first so the OAuth session clears while the name still resolves
codex mcp logout summation
codex mcp remove summation
```

- Exit 0, or a clear “not found / not registered” message → registration is gone; treat as already signed out for that path.  
- Any other failure (CLI missing, permission, unexpected error) → **stop**. Tell the user what failed and how to clear **summation** in the host MCP UI. Do not claim disconnected.

3. **Verify** before confirming: `claude mcp get summation` or `codex mcp get summation` should fail or show no live session / no stale `Authorization` header. If it still shows a configured server with auth material, remove that user-scope entry and re-check.

4. Report **disconnected** only after host disconnect or a successful remove **and** verification. Next, the `signin` skill re-runs the connect flow.

## Internal vs external

| | After sign-out |
|---|---|
| **External** | Next sign-in is production/plugin default only — no env picker. |
| **Internal** (`SUMMATION_PLUGIN_INTERNAL=1`) | Next sign-in asks **environment** again and re-applies the allowlisted MCP URL; **tenant** is whatever org they approve in the browser (switch org on the web app first if needed). |

Env and tenant are both pinned at sign-in. Changing either always means sign out → sign in.

## Rules

- Do not use `sum_api.py logout` as the primary path (legacy device-login).
- If the host still shows an `Authorization` header on **summation**, remove that user-scope entry so headerless OAuth can work.
- Never print tokens while inspecting MCP config.
