Connect OpenBrain to Claude

Anthropic’s Claude apps (Desktop and supported web experiences) can attach MCP servers so Claude can search and save memories in OpenBrain.

Before you start

• Create your account and API key
• Confirm your OpenBrain URL (from your team or the dashboard)

Claude Desktop (MCP)

1. Install or update Claude Desktop to a version that supports MCP connectors.
2. Open Settings → Connectors (or Developer → MCP, depending on your app version).
3. Add a custom MCP server:
   • Server URL: https://YOUR_OPENBRAIN_HOST/mcp
   • Authentication: provide your OpenBrain API key when prompted, or use Sign in with OpenBrain if OAuth is offered (MCP OAuth).
4. If the UI asks for extra headers, add:
   • X-Organization-Id: your organization UUID
5. Enable the OpenBrain connector for new chats.
6. Test: ask Claude to “check OpenBrain health” or “search my memories for …” and confirm it calls openbrain_health or memory_search.

Claude on the web

Web Claude may expose MCP or connectors only on certain plans or betas. If you do not see connector settings:

• Use Claude Desktop for MCP today, or
• Check Anthropic’s current documentation for “MCP” or “connectors.”

Tips for everyday use

• Tell Claude explicitly when to remember something (“save this to OpenBrain”) so it calls memory_ingest.
• Before long sessions, ask it to search OpenBrain for relevant context.
• Owners can review what was written in the dashboard Audit log (no raw message text is stored in audit metadata).

Troubleshooting

• OAuth redirect errors: your host must allow the claude:// callback scheme in production (MCP OAuth).
• Wrong organization: verify X-Organization-Id matches the org that owns the API key.
