Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "second-brain": {
      "command": "npx",
      "args": ["mcp-remote", "https://<your-worker-url>/mcp"]
    }
  }
}

Restart Claude Desktop, then add the custom instructions from the CLAUDE_INSTRUCTIONS.md file to Settings → Custom Instructions.

claude mcp add second-brain "npx" "mcp-remote" "https://<your-worker-url>/mcp"

Create ~/.claude/CLAUDE.md with the instructions from CLAUDE_INSTRUCTIONS.md, changing the source line to "claude-code".

In claude.ai → Settings → Integrations → Add custom connector:

Field	Value
Name	`second-brain`
Remote MCP server URL	`https://<your-worker-url>/mcp`

This makes your second brain available in the claude.ai web app and Claude iOS app automatically.

Any MCP-compatible client can connect using the same URL:

https://<your-worker-url>/mcp

For ChatGPT custom instructions, see CHATGPT_INSTRUCTIONS.md.

No auth token is required for the MCP endpoint — the Worker URL itself acts as the access control for personal use.
