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). The first read asks you to pick a tab in Chrome.

Install

Claude Code plugin (the tools and the skill together):

/plugin marketplace add amflimited/threadfox-lite
/plugin install threadfox-lite@threadfox

Claude Code, the MCP server only:

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

Claude Desktop: download the .mcpb file from the latest release 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).
