About posterly
posterly is an MCP server published by the GitHub account awpthorp. Validate, schedule, publish, and analyze social content across 18 platforms with posterly.
It runs on your own machine: your AI client starts it from the npm package posterly-mcp-server at version 0.58.0, or you can connect to the hosted version instead.
It asks for one secret: POSTERLY_API_KEY. Give it a key with the least access that still works.
Version 0.58.0 was published on 28 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 10 automated checks on the registry entry and the package code: 8 pass, 0 warn, 0 fail, 2 info. How we check.
