claude mcp add rcs-campaigns -e 'RCS_GATEWAY_URL=<RCS_GATEWAY_URL>' -e 'RCS_AGENT_KEY=<your rcs_agent_key>' -- npx -y @rcs-campaigns/agent-toolkit@0.1.10 rcs-mcp

Environment variables

  • RCS_GATEWAY_URL Optional. Base URL of the RCS Campaigns agent gateway; defaults to the hosted production gateway. Set it only to target dev or a local gateway — a key is tied to the environment it was minted in, so it must match the environment that issued RCS_AGENT_KEY.
  • RCS_AGENT_KEY required secret Scoped agent key (rcsk_live_…) created in Settings → API keys. Grants only the scopes selected at mint time. Treat it like a password.
