OpenPost: MCP server, setup and security

What OpenPost does

According to its repository: “Manage social publishing workflows through OpenPost”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. OpenPost is listed under Image, video and audio, a category of 67 servers in the directory, where it ranks #5 by stars.

Topics declared by the repository: golang, social-media, svelte, automation, self-hosted, content-creation.

Installing and connecting OpenPost

Distribution modes declared in the official MCP registry:

• remote server (streamable-http): you connect to it by URL, with nothing to install locally

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to OpenPost. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on March 21, 2026, the getopenpost/openpost repository has 755 stars and 102 forks, with 6 open issues. It has more stars than 90% of the servers in the directory. It received changes this month. Version published in the registry: 1.32.4 (October 6, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
