The best and worst hours to post in r/mcp

In our sample of 800 recent and top r/mcp posts, activity and scores peak around Monday 8am UTC, and are weakest around Tuesday 12pm UTC. Based on posts sampled through Sep 5, 2026.

Estimated survival rate

99%

of 468 recent r/mcp posts we sampled were still publicly visible about a day later.

How this is measured

Estimate. We sample recent public posts and check again about 18 hours later to count how many are still publicly visible. Posts removed at the moment of submission never become publicly visible at all, so the true removal rate is at least this high. Last sampled Sep 4, 2026.

r/mcp rules: what actually gets removed

Each rule below is paired with the way it is most likely enforced. Where the rules state a number, we quote it. Where they do not, we say so instead of guessing.

  1. 1.No waitlists

    Enforcement varies

    If you are working on a service, you are welcome to share it with the community after its fully launched. To combat spam, we don't allow links to announcements of future-services until they are barely anything more than a landing page.

  2. 2.No AI generated slop

    Enforcement varies

    There has been a wave of AI-generated slop used to promote random services, usually disguised as sensational topics like MCP security. Such content will result in a ban.

  3. 3.No astroturfing

    Enforcement varies

    Self-promotion is allowed with proper disclosure. Anyone caught promoting their product while pretending to be an unaffiliated user will be permanently banned.

  4. 4.Use showcase tag to share your work

    Enforcement varies

    If you've built something in the MCP ecosystem, use showcase tag to indicate authorship and intent of demonstrating your work to others.

r/mcp does not publish karma or account-age minimums in its rules. Subreddits often enforce unpublished filters on top of what they write down, which is why posts from new accounts can vanish without a message here.

Can you self-promote in r/mcp?

Yes, within reason. r/mcp allows self-promotion, but Reddit's sitewide 9-to-1 guideline still applies: accounts that mostly post their own links get filtered as spam regardless of sub rules. The sub's own wording: "Self-promotion is allowed with proper disclosure.".

What gets removed in r/mcp

  • Low karma or a new account

    r/mcp publishes no karma or age minimum, but unpublished account filters are common at this size. New accounts should comment before posting.

  • AI-generated content

    r/mcp removes content it judges to be AI-generated. Obvious AI phrasing in a draft raises removal risk even when a human wrote most of it.

  • Reddit's sitewide spam filter

    A separate layer before the subreddit ever sees your post. New accounts posting links, URL shorteners, and repeated domains are its favorite targets. Removals are instant and silent.

  • A shadowbanned account

    If the account itself is shadowbanned, every post looks live to you and invisible to everyone else, in any subreddit.

r/mcp posting questions

Can I post links in r/mcp?

Yes. r/mcp accepts link posts. The usual sitewide traps still apply: URL shorteners, affiliate parameters, and brand-new domains get filtered fast, and promotional links are judged against the sub's self-promo rules. One clean link to the original source is the safe pattern.

Does r/mcp require karma to post?

r/mcp does not publish a karma minimum. That does not mean there is none: many subreddits enforce unpublished karma and account-age filters that remove posts silently. If your account is new or has little karma, that is the first thing to rule out when a post disappears.

Can you self-promote in r/mcp?

Yes, within reason. r/mcp allows self-promotion, but Reddit's sitewide 9-to-1 guideline still applies: accounts that mostly post their own links get filtered as spam regardless of sub rules. The sub's own wording: "Self-promotion is allowed with proper disclosure.".

Is r/mcp strict?

Relaxed, by our estimate (10/100 on our strictness scale, from its measured removal rate, 4 rules, and its stated gates). About 1% of recent posts disappeared within a day in our sample. Strictness is about enforcement, not hostility: a strict sub is predictable if you follow its rules.

Does r/mcp allow AI-generated content?

No. r/mcp removes content it judges to be AI-generated. That includes obviously AI-phrased text even when a human edited it, so rewrite drafts in your own voice before posting here.

What is the best time to post in r/mcp?

Based on our sample of recent and top posts, activity and scores peak around Monday 8am UTC and Friday 2pm UTC. Treat this as a starting point, not a guarantee: a post that breaks a rule gets removed at any hour. The heatmap on this page converts these windows to your local time.

Why do posts get removed in r/mcp?

The most common reasons are link policy violations, plus the layers every subreddit has: Reddit's sitewide spam filter, unpublished AutoMod rules, and account-level gates like karma and age. In our recent sample, roughly 1% of r/mcp posts disappeared within about a day of going up. Many removals are silent, so checking your draft first beats finding out after.
