Windsurf
Give Windsurf's Cascade the Hanzo toolset and the hosted Hanzo MCP endpoint.
Hanzo MCP
Two ways to give Windsurf 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.
In Cascade, open the MCP menu and choose Open MCP config file (~/.config/devin/mcp_config.json), then add this.
{
"mcpServers": {
"hanzo-cloud": {
"serverUrl": "https://api.hanzo.ai/v1/mcp",
"headers": {
"Authorization": "Bearer sk-..."
}
}
}
}In Cascade, open the MCP menu and choose Open MCP config file, then add this.
{
"mcpServers": {
"hanzo": {
"command": "npx",
"args": ["-y", "hanzo", "mcp"]
}
}
}Cascade's Open MCP config file action opens ~/.config/devin/mcp_config.json on macOS and Linux and %AppData%\devin\mcp_config.json on Windows. A mcp_config.json can also sit in a project at .devin/mcp_config.json.
