FeedLetter MCP by usefulapi

FeedLetter MCP by usefulapi

Use your FeedLetter account from Claude, Cursor, or any MCP client. Read your surveys, votes and feedback, load Wall of Love feedback, and create new surveys. Hosted, no local install: connect with your own credentials.

Live endpoint: https://feedletter.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://feedletter.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http feedletter https://feedletter.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "feedletter": {
      "url": "https://feedletter.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your FeedLetter credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/feedletter/

On first connect you provide a FeedLetter API key (FeedLetter → Account → API Keys, owner only; a Read & write key also lets it create surveys). The server validates it and stores it per user. No keys go in config files.
