client:Cline transport:streamable-http tool:mailblaze_unsubscribe_subscriber

Add Mail Blaze MCP by usefulapi to Cline

  1. 01

    Open ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "mailblaze": {
      "url": "https://mailblaze.usefulapi.io/mcp"
    }
  }
}
  1. 02

    Save the file and restart Cline.

  2. 03

    Ask for something mailblaze_unsubscribe_subscriber does. Cline lists the server's tools on connect and calls mailblaze_unsubscribe_subscriber itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Mail Blaze MCP by usefulapi's identifier in your config matches the one above exactly.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 25 October 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
