"""Install MCP: Context7 (up-to-date library docs) — npm global + registry + Sync Tools + generalist binding.

Run from repo root: python oclaw/scripts/install_mcp_context7.py

Requires CONTEXT7_API_KEY in src/_local/mcp_local.env or data/mcp_local.env (or environment). Default OPS_MCP_ENV_ALLOWLIST
now includes CONTEXT7_API_KEY when unset; restart gateway after changing env.
