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.

L1 · Tools

$0 · 1–2s per call

Raw data plumbing. Objective filters only. Use for exploratory, ad-hoc queries.

L2 · Prompts

~$0.15 · 25–60s per run

Analysis frameworks your AI agent executes with your project context. Flexible, LLM-powered reasoning for novel scenarios.

L3 · Compiled Pipes

$0 · 0.8ms–3s per run

Pre-forged DAG workflows. Zero LLM tokens per invocation. In-process pure-transform pipes run at 0.8ms — 293× faster than subprocess mode. No other Reddit tool offers this.

Switching from GummySearch?

GummySearch had 135,000 users when Reddit killed it in Nov 2025. If that was your workflow, RDK covers every discovery tool GummySearch had — plus the account-safety layer GummySearch never built. 5-minute migration, and every replacement you've tried since (Subreddit Signals, Redreach, F5Bot, Popsy AI, RedShip) is a dashboard; RDK lives inside your agent.

Add to your MCP client

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.
