OpenClaw
Give OpenClaw the Hanzo toolset and the hosted Hanzo MCP endpoint.
Hanzo MCP
Two ways to give OpenClaw Hanzo's tools. API key is the hosted endpoint, https://api.hanzo.ai/v1/mcp, with a key from hanzo.app sent as Authorization: Bearer sk-.... Local is hanzo-mcp on your machine, started with npx -y hanzo mcp (needs Node.js). With no key set it uses the sign-in hanzo login stored, so there is no key to paste (MCP). Replace sk-... with your key.
Run this with the Gateway stopped. It saves the server under mcp.servers in ~/.openclaw/openclaw.json.
openclaw mcp set hanzo-cloud '{"url":"https://api.hanzo.ai/v1/mcp","transport":"streamable-http","headers":{"Authorization":"Bearer sk-..."}}'Run this with the Gateway stopped.
openclaw mcp add hanzo --command npx --arg -y --arg hanzo --arg mcpOpenClaw keeps its servers under mcp.servers in ~/.openclaw/openclaw.json. Saving a server with openclaw mcp set or openclaw mcp add needs the local Gateway stopped; openclaw mcp list shows what is saved.
