Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.

Permissions Found in Source Code

Found by scanning the linked source code. This listing connects to a hosted endpoint, so none of this runs on your machine: it describes what the server software does where it is hosted.

HTTP Network Access

Connects to external APIs or services over the internet.

How to Connect

Remote Plugin

No local installation needed. Your AI client connects to the remote endpoint directly.

Add this to your MCP configuration to connect:

{
  "mcpServers": {
    "app-letterly-mcp": {
      "url": "https://mcp.letterly.app/mcp"
    }
  }
}

Letterly MCP Server

Dictate anywhere with Letterly, then find, rewrite and translate your voice notes in your AI chat.

This repository hosts documentation only. Letterly MCP is a hosted remote server, so there is nothing to install or run locally.

What it does

Connect your Letterly account to an AI assistant (GitHub Copilot, Claude, ChatGPT, Cursor and others) and ask it to:

  • search and read your voice notes
  • create, edit and delete notes
  • rewrite a note in another style or translate it
  • manage your custom rewrite prompts

Setup

  • Server URL: https://mcp.letterly.app/mcp
  • Transport: Streamable HTTP
  • Sign-in: OAuth with your Letterly account. You'll be asked to sign in the first time you connect.

VS Code / GitHub Copilot

Add this to .vscode/mcp.json in your workspace (or to your user MCP configuration):

{
  "servers": {
    "letterly": {
      "type": "http",
      "url": "https://mcp.letterly.app/mcp"
    }
  }
}

Then start the server from the MCP view and sign in to Letterly when prompted.

Other clients

In Claude, ChatGPT, Cursor or any other MCP client, add a custom (remote) MCP server with the URL above and sign in when asked.

Example prompts

  • "Find my notes about the marketing plan from last week"
  • "Rewrite my latest note as a short email"
  • "Translate my note about the trip into German"
