MCP-native · account-safety first · survives Reddit API wars

Never get your Reddit account killed again

The MCP server your growth agent uses inside Claude Code, Cursor, and Codex. Pre-flight every post against karma, age, and sub-rules before it ships — for free. Pro unlocks enriched data via a browser bridge Reddit can't revoke.

Built for devs, not dashboard users. If you want a web UI, try Subreddit Signals or Redreach — they're good at that. RDK is the MCP server you compose from inside Claude Code / Cursor / Codex when your agent needs to do Reddit research without killing an account along the way.

GummySearch died Nov 2025 — 135K users, 10K paying customers, four years of work, gone overnight when Reddit revoked their commercial API. RDK takes two structurally safer bets: RSS for Free-tier discovery (no API keys to revoke), and a logged-in browser bridge for Pro-tier enrichment (same JSON pages your browser sees — Reddit can't revoke this without breaking their own frontend).
9 tools · 6 prompts · compiled pipes

Stop your agent from killing the account. Every post your growth agent ships without a pre-flight check is a coin-flip against automod. These three tools are Free because an unguarded agent is a liability, and we'd rather you never lose the account in the first place.

reddit_pre_flight_check

Does this account clear the target sub's karma / age / self-promo gate BEFORE you post? Verdict: go / warning / blocked with itemized blockers like “you have 12 karma, r/SaaS requires 50”. Call this at the start of every outreach workflow.

reddit_shadowban_check

Is the logged-in account silently banned from r/all? Asks r/ShadowBan's community bot. Slow (5 min bot reply), rate-limited to once per 24h — not for automation, only for “why are my posts invisible?” moments.

reddit_profile

Read any account's public karma & age. Omit user to read your logged-in account. Feeds pre-flight with no extra API calls.

Demand intelligence. RSS-first, zero API keys, survived the apocalypse that killed GummySearch.

reddit_search

Search Reddit with must_contain and exclude filters. Pro adds real scores & comment counts.

reddit_post

Fetch a single post with its comments. Pro tier returns full comment threads with scores.

reddit_subreddit

Survey a community: recent posts, description, and (Pro) rules + self-promotion policy.

reddit_discover

Find subreddits where a target audience lives. Ranked by real mention count in query results.

reddit_solutions

Find sales-ready “looking for a tool / alternative to X” posts inside a target subreddit — prequalified outreach leads.

reddit_account_health_deep PRO

Catches “Reddit is silently killing my posts” cases that pre-flight can't see. Reads removed_by_category from /user JSON via Tap's logged-in browser bridge — same pages your browser sees, not the commercial API that killed GummySearch.

Plus 6 MCP prompts that teach your AI agent how to score demand, map competitors, and plan outreach — executed by your own Claude / Cursor / Codex with full project context. And compiled pipes that pre-forge stable workflows into zero-cost DAGs.

Install

One command. Requires Node.js 16+.

$ npm install -g reddit-demand-kit
2

Add to your MCP client

Same JSON works in Claude Code (~/.claude.json), Cursor (.cursor/mcp.json), and Codex — or any other MCP host.

{ "mcpServers": { "rdk": { "command": "rdk", "args": ["mcp"] } } }
3

Use it

Ask your agent: “Before we post to r/SaaS, run a pre-flight check on this account and tell me if it'll get killed.” RDK's 9 tools and 6 analysis prompts are available automatically — safety first, then discovery.
