1. 1
   Devin agent and Devin CLI (Devin Desktop, formerly Windsurf): add MegaMCPs under mcpServers in ~/.config/devin/mcp_config.json (.devin/mcp_config.json for one project) and save:

   {
     "mcpServers": {
       "megamcps": {
         "url": "https://mcp.megamcps.com/mcp"
       }
     }
   }

   Copy
2. 2
   Or skip the file and let the Devin CLI write the entry:

   devin mcp add megamcps https://mcp.megamcps.com/mcp

   Copy
3. 3
   Sign in from a terminal. Your browser opens MegaMCPs: check the account and click Allow.

   devin mcp login megamcps

   Copy
4. 4
   Legacy Cascade agent: open the Cascade panel's actions menu, choose Open MCP config file (the same file; older Windsurf: ~/.codeium/windsurf/mcp_config.json), add the same entry, refresh the MCP servers in Cascade and sign in when asked. Your browser opens MegaMCPs: check the account and click Allow. Cascade also accepts url; older versions need serverUrl instead.

Good to know

• These apps limit how many tools they load. Turn on fewer services, or wait for per-client tool selection.
• Cascade loads at most 100 tools in total.
• To stay under it, list the tools you don't need under disabledTools in the megamcps entry.

If it doesn't work

• Sign-in fails with invalid_client? Remove the server from the app and add it again.
