# Bifrost Onboarding

Walk through full Bifrost setup in Claude Code (steps 1–5), then optionally
Claude Desktop (step 6).

## Step 1 — Get your gateway URL and virtual key

Ask your gateway operator for two values:
- The gateway `/mcp` endpoint URL → `BIFROST_URL`
- Your personal virtual key (`vk_…`) → `BIFROST_VK`

## Step 2 — Run the installer

From the plugin root (or use the slash command — see below):

```bash
export BIFROST_URL=https://<your-gateway-host>/mcp
node "${CLAUDE_PLUGIN_ROOT}/bin/install.js" --key vk_<your-key>
```

The installer:
- Registers the bifrost MCP server via `claude mcp add --scope user` (idempotent — re-running replaces the same entry; it never edits config files directly).
- Without `--key`, stores the `${BIFROST_VK}` runtime template. It does NOT modify your shell profile — you must add `export BIFROST_VK=…` to `~/.zshrc` (or `~/.bashrc`) yourself for the key to persist across sessions.

Or run the slash command from inside Claude Code (same installer):

```
/bifrost-setup
```

## Step 3 — Persist the env vars, then restart Claude Code

Add the export lines to your shell profile so they survive new shells:

```bash
echo 'export BIFROST_URL=https://<your-gateway-host>/mcp' >> ~/.zshrc   # or ~/.bashrc
echo 'export BIFROST_VK=vk_<your-key>' >> ~/.zshrc
source ~/.zshrc
```

Then restart CC so the MCP server and hooks are loaded.

> macOS note: Claude Code launched from the Dock or Spotlight does NOT inherit
> `~/.zshrc` exports. Launch CC from a terminal (`open` from a shell, or run the
> `claude` CLI), or set the env vars via a launchd plist, otherwise the gateway
> sees no key.

## Step 4 — Smoke check

Run these checks to confirm everything is live:

1. **MCP loaded:** type `/mcp` — `bifrost` should appear in the server list.
2. **Skill search works:** if your gateway exposes a skill server, call
   `mcp__bifrost__<skills-server>-skill_search` with `"test connection"` — should return results.
3. **Memory tools:** if your gateway exposes a memory server, call its search tool
   (`mcp__bifrost__<memory-server>-search`) with a short query — should return results or an empty list.
4. **Session context:** open a new session — the bifrost context block should appear at the top.

## Step 5 — Add the skill-discovery MUST-stanza (recommended)

Offer to append the stanza from `guidance/AGENTS-skill-stanza.md` to the user's
`~/.claude/CLAUDE.md`. Check first — skip if `## Skill Discovery` heading is
already present (idempotent).

```bash
grep -q "## Skill Discovery" ~/.claude/CLAUDE.md \
  || cat "${CLAUDE_PLUGIN_ROOT}/guidance/AGENTS-skill-stanza.md" >> ~/.claude/CLAUDE.md
```

## Step 6 — Claude Desktop (optional)

Ask whether the user also wants the gateway in Claude Desktop. If yes, the
plugin install itself is the setup: there is no separate registration step.

1. Desktop Code tab: `+` button next to the prompt box → Plugins → Add
   plugin. Desktop Chat and Cowork tabs, and claude.ai: Customize (left
   sidebar) → Plugins → Browse plugins → Add from a repository.
2. At the install prompt, fill in the gateway URL (keep the default unless
   the operator gave you a different one) and paste the `vk_...` virtual key
   the operator issued you. Leave the OAuth client ID field empty unless told
   otherwise.
3. Verify: gateway tools appear in Desktop after install.

Leaving the virtual key blank tries OAuth instead, and that path does not
fully work yet without an operator-issued OAuth client ID. Even with one, the
identity provider still needs to allow the redirect URI
`http://localhost:51789/callback`. Recommend a virtual key for now; point to
`/bifrost-debug` for the exact errors if the user wants to try OAuth anyway.

If login succeeds but requests fail with `no_virtual_key`, the operator has
not mapped the user's identity to a virtual key yet. Ask them to add the user.

Fallback, only for plugin versions before 1.5.0 or installs that cannot use
the plugin at all: add an `mcp-remote` entry to
`~/Library/Application Support/Claude/claude_desktop_config.json` (see README
→ Legacy fallback: Desktop local proxy for the exact snippet; requires Node,
and the file then holds the VK, so treat it as a secret).

## Troubleshooting

If anything fails, run `/bifrost-debug` for guided diagnosis.
For manual MCP wiring, run `/bifrost-mcp-setup`.
