What is posteverywhere?

An MCP connection for publishing and scheduling social-media content from Gemini CLI. It supports media uploads, captions, campaigns, and analytics across the listed social platforms.

Use it to publish or schedule content, upload media, create captions and campaigns, and view social-media analytics on supported platforms.

Managing posts across many social networks otherwise requires separate tools and workflows. This provides one agent-accessible connection for those publishing and measurement tasks.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/posteverywhere/mcp

Made for: Gemini CLI.

Security

Grade A, and why

posteverywhere scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 15d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
