ThreadFox Lite

Free, read-only Reddit tools for Claude Desktop, Claude Code, Codex and any MCP client, plus a reddit-rules-first agent skill.

• subreddit_rules: a subreddit's rules, size and description, with the self-promotion rules flagged. Call it before writing a post.
• find_communities: subreddits about a topic ("bakery marketing", "indie games"), each with its self-promotion rules flagged and whether it mentions a promo thread.
• account_check: a Reddit account's age, karma and standing, and whether its recent posts are removed or hidden from search (the practical sign of a spam filter or shadowban).
• post_status: whether a post is still live, removed by moderators or deleted, with score and comments. Check at 1, 6 and 24 hours.
• threadfox_full_kit: what the full ThreadFox kit adds (finding conversations where people ask for what you sell, posting from your own Chrome, replies, an outcome ledger, a 12-module course).

Reads only, through your own signed-in Chrome. Reddit now sends every signed-out request, including its public JSON, to a login page, so ThreadFox Lite reads the way you do: in your Chrome, signed in as you, one small read at a time. It never posts, votes or changes anything, and needs no Reddit API keys. One-time setup: Microsoft's Playwright Extension in the Chrome where you are signed in to Reddit. Node.js is fetched for you if you don't have it (the official build from nodejs.org into ~/.threadfox/runtime, checked against its published SHA-256; nothing installed system-wide). It stays light on your computer: one Reddit read at a time across every ThreadFox app on the machine, and its Chrome connection closes after 10 idle minutes and never leaves background processes behind. The first read asks you to pick a tab in Chrome.

Install

Claude Code:

claude mcp add threadfox-lite -- uvx threadfox-lite

Claude Desktop: download threadfox-lite-0.2.8.mcpb and open it; if Windows asks which app should open it, choose Claude. Claude Desktop sets up Python for it by itself.

Codex (~/.codex/config.toml):

[mcp_servers.threadfox-lite]
command = "uvx"
args = ["threadfox-lite"]

Any other MCP client: run uvx threadfox-lite (the package is on PyPI).

The source repository and the Claude Code plugin marketplace are temporarily unavailable on GitHub. The installation methods above work without GitHub.

The skill

Download reddit-rules-first and save it as SKILL.md in a reddit-rules-first folder in your agent's skills directory. It works on its own in any agent that reads skills: rules first, one post per community, disclose, check what stayed up.

Also listed in the official MCP Registry as io.github.amflimited/threadfox-lite.
