Quick picks: what are you doing?
- You want subreddit data inside your assistant with no signup: CommunityMentions, free.
- You want your agent to find threads and queue replies: Bazzly, $199 a month, or CrowdReply, from $79 a month.
- You want the lowest monthly price with MCP named on the plan: RedditGrow Growth, $19 a month.
- You want someone else to post and no agent work at all: a done-for-you service needs no MCP server.
The four servers, side by side
Ranked on two questions, in this order: can someone try it with no account, and can it change anything or spend money? A server that answers no to both risks the least when you hand it to an agent. Every cell was read or called on November 9, 2026.
| Rank and tool | Endpoint | Try with no account? | Can it change or spend? | Price with MCP |
|---|---|---|---|---|
| 1. CommunityMentions (ours) | https://communitymentions.com/api/mcp | Yes, both tools | No, read-only | $0 |
| 2. Bazzly | https://api.bazzly.ai/mcp | Help-center tools only, at www.bazzly.ai/mcp | Yes: queues replies and DMs, sets credit top-ups | $199 a month, 170 credits, 7-day trial |
| 3. CrowdReply | https://mcp.crowdreply.io/mcp/client | No, answers 401 without sign-in | Yes: creates tasks and spends credits, with a two-step confirm | From $79 a month |
| 4. RedditGrow | https://redditgrow.ai/mcp | No, answers 401 and asks for a bearer key | Its page doesn't say what the server can change | $19 a month Growth, or $79 one-time Founder Pack |
1. CommunityMentions
- Best for: research: which subreddits fit a product and how often AI answers cite them.
- Endpoint: https://communitymentions.com/api/mcp
- Access: no account and no key. Setup for Claude and ChatGPT.
- Tools: two, find_subreddits and get_subreddit, over 35,381 AI citations in data dated November 8, 2026.
- Where it falls short: it can't find live threads, draft a reply or place anything. Our posting service runs separately and isn't reachable through this server.
2. Bazzly
- Best for: an agent that works a reply queue, if you already pay for Bazzly.
- Endpoint: https://api.bazzly.ai/mcp, with a public help-center server at https://www.bazzly.ai/mcp.
- Access: a bearer API key with read, write and top-up scopes, per its MCP page. The handshake answered without a key; the page says each request carries its own auth.
- Tools: finding opportunities, generating and queuing replies, DMs, upvote tasks and credit top-ups. A public call listed search_help, get_help_article and submit_feedback.
- Where it falls short: $199 a month is the only plan, and each further active project costs the same again.
3. CrowdReply
- Best for: visibility tracking and task orders from Claude, Cursor or Codex.
- Endpoint: https://mcp.crowdreply.io/mcp/client
- Access: an account; the endpoint answered 401 Unauthorized with no credentials. Its FAQ lists "Do I need an API key?" with no answer shown.
- Tools: 14 read tools listed, such as find_reddit_threads and list_llm_citations, and 9 write tools, such as create_task and send_upvotes. Tools that spend credits ask for confirmation first.
- Where it falls short: a comment costs $10 from the plan's credits on Starter, and its FAQ lists questions on API keys and plans with no answer shown.
4. RedditGrow
- Best for: the lowest monthly price with MCP named on the plan.
- Endpoint: https://redditgrow.ai/mcp
- Access: a bearer key; the endpoint answered "Missing Authorization: Bearer <key>".
- Tools: its home page says "Run it from Claude, Cursor or a cron" and doesn't list the tools.
- Where it falls short: the home page links no MCP documentation, and it doesn't say whether the server can post.
When a data-only server is enough
If your agent only needs to decide where to look, a read-only server does the job at $0, and nothing it does can spend money or touch an account. You need one of the paid three when you want the agent to queue replies or orders. Decide that before connecting anything, because a tool that can spend credits needs the same care as a shared card.
Where we found no MCP server
For these eight we tried the handshake on four URL patterns and read each home page for any mention of MCP on November 9, 2026. A server could exist at another address; none of the usual ones answered.
| Service | /mcp on its site | /api/mcp on its site | mcp. subdomain | MCP on home page |
|---|---|---|---|---|
| ReddiReach | 404 | 404 | 404 | No |
| OutreachBloom | 404 | 404 | No such host | No |
| Mention.Broker | 404 | 404 | No such host | No |
| Growth Marketing Pro | 404 | 404 | No such host | No |
| Vettted | 404 | 404 | No such host | No |
| Soar | 404 | 404 | No such host | No |
| ReplyAgent | 404 | 404 | No such host | No |
| Scaloom | 404 | 404 | No such host | No |
How we checked
We sent each URL a standard MCP initialize request and counted a server as live if it completed the handshake or refused with an authentication error at an address its own site names. The official MCP registry, searched for "reddit" the same day, returned a full page of 100 rows when we set the limit to 100, many of them repeat versions of the same server. Most are data scrapers or Reddit Ads tools rather than marketing services, so they aren't ranked here.
