01 · Why connect
Le Chat is now Vibe. Work custom MCP connectors typically need an admin and a server URL. Vibe Code CLI may not yet support MCP OAuth — if login fails, use a client with OAuth.
Work: UI connector URL. CLI: config.toml / ~/.vibe/config.toml with http or streamable-http. Prefer OAuth-capable clients if the CLI cannot complete Make0 login. The Make0 MCP URL is https://make0.ai/mcp. Mistral Vibe 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 Mistral Vibe
Install Make0 Brain in 4 steps
- 01
Pick Work or Code
Vibe Work uses admin custom connectors. Vibe Code uses CLI/IDE config.toml.
- 02
Paste the MCP URL
Use https://make0.ai/mcp as the server URL.
- 03
Authorize if prompted
Complete Make0 OAuth when the client supports it. If the CLI cannot OAuth yet, connect from Claude, Cursor, or Codex instead.
- 04
Test memory tools
Ask Vibe to search Make0 Brain.
03 · Vibe Code CLI
Copy this into Mistral Vibe
Use HTTP or Streamable HTTP. Do not wrap Make0 as a local stdio command. This config signs in with OAuth.
[mcp_servers.make0-brain]
type = "http"
url = "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. If Vibe Code CLI can’t complete OAuth, an API key is the simplest way in. Add the header to the server entry. Check the Vibe docs for the exact field name in your version.
Vibe Code CLI
[mcp_servers.make0-brain]
type = "http"
url = "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 Mistral Vibe’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 Mistral Vibe
How do I connect Make0 Brain to Mistral Vibe?+
Add Make0 as a remote HTTP MCP server using https://make0.ai/mcp. In the Make0 connect dialog, choose OAuth and Mistral Vibe will open a sign-in so you can pick which brains it can use. On Pro or Max, if Mistral Vibe 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.
