How to connect ReminderIt to Claude Desktop (step-by-step)

Claude Desktop supports the Model Context Protocol, which lets you give Claude access to external tools. ReminderIt's MCP server is one of those tools — once connected, you can ask Claude to set a phone call reminder for you and it will happen, automatically, at the right time.

What you need before you start

A ReminderIt account (free to start at reminderit.com) and an API key from the API Keys section of your dashboard. Python 3.11 or higher installed on your machine. Claude Desktop installed (available for Mac and Windows at claude.ai/download).

Step 1: install the MCP server

Open a terminal and run: pip install reminderit-mcp. This installs the reminderit-mcp command-line tool globally.

Step 2: add it to your Claude Desktop config

Find your claude_desktop_config.json file. On Mac it lives at ~/Library/Application Support/Claude/claude_desktop_config.json; on Windows at %APPDATA%\Claude\claude_desktop_config.json. Add the following inside the "mcpServers" object: { "reminderit": { "command": "reminderit-mcp", "env": { "REMINDERIT_API_KEY": "rmt_your_key_here", "REMINDERIT_API_URL": "https://api.reminderit.com" } } }

Step 3: restart Claude Desktop and test

Quit and reopen Claude Desktop. In a new chat, ask: "Set a reminder to take my evening medication at 9pm London time every day." Claude will use the ReminderIt tools to create the reminder and confirm the details back to you.
