-- **MCP preflight (fail fast):** confirm this session actually loaded the lane's required Playwright MCPs (their `browser_*` tools must be available) — `playwright` and a local-QC MCP are always required for Stage 3/6. `ccam lanes mcp sync` (F, not built yet) would normally do this for you; until then, tell the human to configure `.mcp.json` manually and restart the session if a required MCP is missing. Catching this at Stage 0 costs a minute; catching it at Stage 13 strands a merged feature unverified.
+- **MCP preflight (fail fast):** if this is the lane's first run, or a required Playwright MCP's `browser_*` tools aren't available in this session, run `ccam lanes mcp sync` — it relocates the source repo's already-configured MCP servers into this lane's `.mcp.json`. If the source repo has none configured (`ENOMCPCONFIG`), tell the human to configure `.mcp.json` manually for the source repo first. Either way, restart the session after syncing so the new config loads — `playwright` and a local-QC MCP are always required for Stage 3/6. Catching this at Stage 0 costs a minute; catching it at Stage 13 strands a merged feature unverified.
 - **Agents preflight:** if this is the lane's first run through this pipeline, run `ccam lanes agents install` once — it writes the `qc-local` and `senior-gate-reviewer` agent definitions into the lane's own `.claude/agents/` (idempotent; re-running just overwrites with the current templates). Stage 6/7 launch these by `subagent_type`; skipping this leaves those stages unable to find the agent.

+### Syncing MCP servers: mcp sync
+
+A lane needs the same MCP servers (Playwright, a local-QC server) as its source repo to run Stage 3/6. `ccam lanes mcp sync` gives it those:
+
+```bash
+ccam lanes mcp sync
+```
+
+Reads the source repo's already-configured `mcpServers` from `~/.claude.json` (normal Claude Code project-scope config — set this up for the source repo once, the same way you would for any project), relocates any absolute path under the source repo to the lane's own directory, pins a `@playwright/mcp` server's `--output-dir` to the lane's `.playwright-mcp` (so proof screenshots land where the proof gallery reads them), and writes `<lane>/.mcp.json`. Also seeds the lane's Chromium browser profiles from the source repo's own — preserves saved logins, and never overwrites a profile that already exists at the destination.
+
+**No permission/settings changes.** Unlike Shipyard's original `lane-mcp-sync.sh`, this command never writes to `<lane>/.claude/settings.local.json` — no auto-approval rules, no `autoMode` bypass entries. A session's `gh`/`git push` commands go through the normal permission prompt like any other command.
+
+A lane whose source repo has no `mcpServers` configured gets a clear `ENOMCPCONFIG` error, not a silently-empty `.mcp.json` — configure the source repo's MCP servers first, then re-run.
+
+Restart the lane's Claude session after syncing — MCP config is read at session start.
