Windsurf (Devin Desktop)

Windsurf was renamed Devin Desktop in 2026. Its Cascade panel still reads remote MCP servers from an mcp_config.json file.

1. In the Cascade panel, click the … (Actions) menu at the top right, go to the MCPs section and click Open MCP config file. Opening it from the app avoids guessing the path, which depends on your version:

   • Devin Desktop (per its docs): ~/.config/devin/mcp_config.json on macOS and Linux, %APPDATA%\devin\mcp_config.json on Windows.
   • Older Windsurf builds: ~/.codeium/windsurf/mcp_config.json (%USERPROFILE%\.codeium\windsurf\mcp_config.json on Windows).

2. Add GoBanana under mcpServers and save:

   mcp_config.json

   {
     "mcpServers": {
       "gobanana": {
         "serverUrl": "https://gobanana.fun/api/mcp"
       }
     }
   }

   The docs accept serverUrl or url for a remote server.

3. Back in the MCPs section, make sure the toggle next to gobanana is on. When it asks you to sign in, your browser opens the GoBanana sign in page.

4. In Cascade, ask: “Use the GoBanana ping tool.”

100 tools

Cascade can use 100 tools in total at a time, across all servers. GoBanana has 17 for the agent. If some are missing, turn off tools you do not need in other servers.

Windsurf does not load Claude plugins. Paste the one line from No plugin?, or save it as a rule. For hand-off, BUILD-PROMPT.md and the AGENTS.md section work here. See Hand off.

What was verified

Checked on 2026-10-12 against the Cascade MCP docs (now at docs.devin.ai), which give the menu path, the serverUrl field, the 100 tool limit, and say OAuth is supported but do not describe the sign in screens. The older Windsurf path comes from current third party guides, not an official page. Windsurf is not installed on this machine, so nothing here was run. If your build cannot sign in to remote servers, use the bridge in Other MCP clients.
