NODELANE ACT / REDDIT-MCP

Reddit MCP for communities, discussions, and actions

Give AI access to Reddit recommendations, community search, posts, and comments through your signed-in browser, a small page at a time.

Start with a community question

The NodeLane Act Reddit adapter includes 26 operations. Read home recommendations, search posts or communities, check community details and rules, and expand post bodies, comment trees, and user content. Compact results retain source URLs and content identifiers for verification.

It uses your browser session without requiring a separate Reddit OAuth application. Website permissions, community rules, and account restrictions still apply. Install from act.nodelane.net/download/.

A community-research workflow

Example prompt: “Find Reddit communities discussing self-hosted AI and give me three candidates with descriptions. In the most relevant community, read five top posts from the past week. Expand comments on only two posts, keeping sources and continuation information.”

Start with search_communities, then use a returned community name with feed. Read rules before drafting a post; a community description is not its full rule set. subreddit uses the short name without the r/ prefix.

site.context({ site: "reddit" })
site.discover({ site: "reddit", operation: "feed" })
site.execute({
  targetId: "<Reddit targetId>",
  operation: "feed",
  args: { subreddit: "selfhosted", sort: "top", time: "week", limit: 5 }
})

List cursors and comment branches differ

Post lists continue with returned after or before values while preserving community, search terms, sort, and time range. search_communities has community cursors; do not mix them with post-list cursors.

Comments can contain unloaded branches. Pass explicit IDs from comments.continuation.children into more_comments, or use comment_id to focus a branch. The tool does not recursively crawl an entire discussion in the background.

Limit list size and max_body_chars before expanding selected posts. Output budgeting is separate from website pagination: resultId continues a local cached response, not the next Reddit page.

Actions after clear authorization

Vote or undo a vote, save or unsave, hide or restore posts, join or leave communities, comment, reply, publish text or link posts, and edit or delete content you may manage.

Example: “Save the second post we just reviewed to my Reddit account.” For publishing, review rules, title, and body first. A draft should remain a draft until submission is explicitly requested.

Community flair, account eligibility, and other requirements can reject publication. The extension does not automatically retry writes, and cancellation or disconnection cannot undo a request already received.

Verification, missing features, and clients

Live read checks covered account, recommendations and continuation, search, community discovery, information, rules, posts, full text, and comments. Writes use mocks and an isolated browser fixture; no live posting, messaging, or deletion was used for acceptance.

Media uploads and complete Reddit Chat management are not implemented. Compatible message sending may create Chat; mark_read only marks read, and unblock only removes an existing block.
