Moon Banking MCP for Devin Desktop

Connect Devin Desktop (formerly Windsurf) to the Moon Banking MCP server.

Devin Desktop is the new name for Windsurf. Cognition shipped the rename as an over-the-air update on June 2, 2026 — the IDE, your settings, your extensions, and your existing MCP configuration all carried over automatically. The Agent Command Center is now the default surface (multi-agent Kanban view, Spaces, ACP-based third-party agents), with the classic editor still one click away. The local coding agent has been renamed from Cascade to Devin Local — same MCP plumbing, ~30% better token efficiency, subagent support, and sandboxing. Cascade itself is end-of-life on July 1, 2026, so new MCP setup should target Devin Local; the configuration below works for both.

Devin Local is built for long-running, multi-file agentic coding tasks — exactly where having reliable external data matters. Wire in the Moon Banking MCP and Devin Local gains live access to the entire Moon Banking dataset (banks, countries, community-rated scores across 14 categories, votes, user stories), so when your agent needs to know about a real bank — its hostname, country rank, crypto-friendliness score, or what users say about its fees — it asks instead of guessing.

Useful for building banking-aware features, generating realistic test fixtures across an entire repo, or simply prompting "find a crypto-friendly digital bank in Portugal and scaffold a project that integrates with its public services" while Devin Local does the heavy lifting.

Devin Desktop reads MCP servers from a single global mcp_config.json file shared with the legacy Windsurf install. Both remote (HTTP) and stdio transports work, and the same file is picked up by Devin Local and Cascade (until Cascade's July 1, 2026 sunset).

Edit (or create) the global config at ~/.codeium/mcp_config.json:

{
  "mcpServers": {
    "moonbanking": {
      "serverUrl": "https://mcp.moonbanking.com/mcp"
    }
  }
}

Restart Devin Desktop. The first request to a Moon Banking tool will trigger an OAuth flow in your browser. After approval, the tools become available to Devin Local (and to Cascade, while it remains).

Alternative: self-hosted (API key)

{
  "mcpServers": {
    "moonbanking-mcp": {
      "command": "npx",
      "args": ["-y", "@moonbanking/mcp-server"],
      "env": {
        "MOON_BANKING_API_KEY": "Bearer mb_sk_..."
      }
    }
  }
}

Verify the connection

Open Devin Desktop, switch to the Devin Local agent (or Cascade, if you have not migrated yet), and head to Settings → Tools — moonbanking should appear with its tool count. Then ask:

List the top five banks in Japan by user rating.

Troubleshooting

  • Server not detected. Confirm Devin Desktop is reading the right config file: open Settings → Tools and use View Raw Config to verify the path. The file is ~/.codeium/mcp_config.json — no windsurf/ subfolder.
  • Auth window won't open. Some Linux distributions require a default browser to be configured (xdg-settings set default-web-browser ...).
  • Still on legacy Windsurf 2.0? The same ~/.codeium/mcp_config.json works — Cascade reads it directly, and Devin Desktop will pick it up automatically when the OTA update lands.
