MCP server

Plan your day, capture tasks, and review what you wrote in your journal just by asking. Dexter exposes a Model Context Protocol server, so any MCP-compatible assistant can connect to your planning data.

Server URL

https://api.dexterplanner.com/functions/v1/mcp-server

What it can do

Most of what you can do inside Dexter is available through the connector. Some examples:

"Plan my day tomorrow around my calendar and top priorities."
"Create a list called 'Q3 Goals' and add three tasks to it."
"Move all unscheduled high-priority tasks to this week."
"Summarize what I journaled about last week."

Claude

Works on Claude.ai, Claude Desktop, and Claude Code.

Claude.ai or Claude Desktop. Open Settings → Connectors → Add custom connector, then paste the server URL.

Claude Code. Run:

claude mcp add --transport http dexter https://api.dexterplanner.com/functions/v1/mcp-server

ChatGPT

Custom MCP connectors in ChatGPT run in Developer Mode. Plus and Pro accounts can read your planning data; writing (creating or updating tasks, lists, goals) needs Business, Enterprise, or Edu.

Open Settings → Apps & Connectors → Advanced settings and toggle Developer Mode on.
Go to Apps & Connectors → Add new connector.
Name it Dexter, paste the server URL, set authentication to OAuth, check "I trust this application", and click Create.

Gemini CLI

Add Dexter to your Gemini CLI config at ~/.gemini/settings.json:

{
  "mcpServers": {
    "dexter": {
      "httpUrl": "https://api.dexterplanner.com/functions/v1/mcp-server"
    }
  }
}

Restart Gemini CLI; it'll prompt you to sign in to Dexter the first time it calls a tool.

Cursor and other MCP clients

Dexter speaks Model Context Protocol over Streamable HTTP. Any MCP-compatible client — Cursor, MCP Inspector, your own agent — can connect using the server URL above.

Authorizing

You'll need a Dexter account. The first time your assistant calls a tool, it'll open a sign-in page where you approve access. After that, your assistant can use the connector until you revoke it from its settings.
