What problem does OpenClaw solve?
It lets one agent runtime receive and reply through several chat channels rather than writing a separate adapter for each. The OpenClaw docs describe a gateway with built-in and plugin channels, plus sessions that separate group conversations from direct messages. The gateway joins messaging transport to agent execution, it does not make either layer safe by default.
An agent harness still needs tools, context, and a stop rule. Agent skills can package recurring work, while MCP can extend the runtime to external systems. Those are architectural choices, not a reason to expose an agent to every chat.
What should be configured before use?
Start with who can start a conversation, which group messages need an explicit mention, and what each channel is allowed to trigger. Then confirm its agent identity, secrets, network boundary, tool access, and logs. Every chat channel is an input boundary, not merely a convenient interface.
Use deterministic agent authorization for each action that can reach company systems. Test impersonation, prompt injection, and an interrupted session before allowing automation to run outside a contained environment.
