01 · Why connect
Windsurf Cascade supports stdio, Streamable HTTP, and SSE. Enterprise policy may restrict custom servers.
Choose Streamable HTTP / URL, not a local command. The Make0 MCP URL is https://make0.ai/mcp. Windsurf can sign in with OAuth on any plan, or use an API key on Pro and Max. Either way, you pick which brains it can use.
02 · How to connect Windsurf
Install Make0 Brain in 4 steps
- 01
Open Cascade MCP
In Windsurf, open Cascade MCP / plugin settings.
- 02
Add HTTP server
Paste https://make0.ai/mcp as the server URL for make0-brain.
- 03
Authorize
Sign in to Make0 and pick brains.
- 04
Enable in Cascade
Turn the server on and ask Cascade to search Brain.
03 · mcp_config.json
Copy this into Windsurf
Use HTTP or Streamable HTTP. Do not wrap Make0 as a local stdio command. This config signs in with OAuth.
{
"mcpServers": {
"make0-brain": {
"serverUrl": "https://make0.ai/mcp"
}
}
}04 · API key
Or connect with an API key
On Pro and Max you can skip the sign-in and use an API key. In Make0, open Connect Brain via MCP, choose API key MCP, and create a key with the brains and access it needs. Add a headers block next to serverUrl in mcp_config.json.
mcp_config.json
{
"mcpServers": {
"make0-brain": {
"serverUrl": "https://make0.ai/mcp",
"headers": {
"Authorization": "Bearer YOUR_MAKE0_API_KEY"
}
}
}
}Replace YOUR_MAKE0_API_KEY with your key. Make0 shows a key once, so keep it somewhere safe. You can revoke it any time in Settings.
05 · System instruction
Tell the agent to prefer Make0 Brain
Paste this into Windsurf’s system instructions or custom instructions so it reads and writes memory through Make0 instead of its own store.
Make0 Brain is my source of truth for durable memory. Always search it before answering about me, my work, people, preferences, or past decisions. Save lasting facts and decisions to Brain. Never guess or invent memories. Use Brain exclusively for durable memory.
Questions
Connecting Windsurf
How do I connect Make0 Brain to Windsurf?+
Add Make0 as a remote HTTP MCP server using https://make0.ai/mcp. In the Make0 connect dialog, choose OAuth and Windsurf will open a sign-in so you can pick which brains it can use. On Pro or Max, if Windsurf accepts custom headers, you can choose API key MCP instead and send the key to this URL as Authorization: Bearer.
What is the Make0 MCP URL?+
The production Make0 Brain MCP endpoint is https://make0.ai/mcp. Use HTTP or Streamable HTTP if the client asks for a transport. Server name: make0-brain.
Does Make0 Brain MCP use OAuth?+
Yes. Compatible clients discover OAuth from the MCP server, you sign in to Make0, and you grant read or write access to specific brains. Two-factor authentication may be required.
Can I use an API key instead of OAuth?+
On Pro or Max, yes, for apps that let you set an HTTP header. Open Connect Brain via MCP, choose API key MCP, and create a key for specific brains or all brains. Send it to https://make0.ai/mcp as Authorization: Bearer. OAuth works on every plan; Free and Lite use OAuth.
