About pixelletter-mcp
pixelletter-mcp is an MCP server published by the GitHub account bitterdev. Send physical letters and faxes through the PixelLetter interface, test mode included.
It runs on your own machine: your AI client starts it from the npm package pixelletter-mcp at version 1.0.3.
It asks for one secret: PIXELLETTER_PASSWORD. Give it a key with the least access that still works.
It also needs PIXELLETTER_EMAIL set before it starts.
Version 1.0.3 was published on 27 July 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
