Overview

Reddit MCP Publisher's local MCP server; no sign-in required; STDIO.

No AI overview yet: these facts come from the registry entry and the server itself.

Installation

In SourceWeft

  1. Open Reddit MCP Publisher in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

Reddit MCP Publisher

[CI] [npm] [MCP Registry] [MIT]

A self-hosted Reddit MCP server for AI agents that can read Reddit, preview drafts and publish with your approval. Connect Codex, Claude Desktop, OpenCode or another MCP client to your own Reddit session. Read posts, threads, subreddit rules, inbox notifications and Reddit Chat; prepare posts, comments or DMs.

The core browser workflow uses no Reddit developer API key. You still need your own Reddit sign-in in Chrome/Chromium. LightPanda is optional for supported authenticated reads, while Chrome handles login, previews and publishing.

Quick start

Requires Node.js 22+, npm and Chrome/Chromium.

bash
npx -y reddit-mcp-publisher setup

For a specific MCP client:

bash
npx -y reddit-mcp-publisher setup --client codexnpx -y reddit-mcp-publisher setup --client claude

Setup creates local MCP configuration and preserves existing browser profiles and encryption keys. Your Reddit password and cookies remain in your browser. Read the installation guide for desktops and headless servers.

What it can do

TaskWhat happens
Read Reddit from an AI agentRetrieve threads, subreddit rules, flairs, own activity, inbox and notification notices
Check eligibility before postingCheck available karma and account-age requirements and block confidently ineligible destinations
Publish posts, comments and repliesBind exact target and text, show a live browser preview, then ask for approval
Reddit Chat and DMsRead conversations and prepare messages with verified recipients and supported attachments
Handle uncertain resultsUse recorded publication state to avoid blindly repeating a write

Reddit's moderation and automation rules still apply. Publishing may fail, and subreddit moderators can remove a post afterward. A changed browser UI or an authentication challenge can stop an operation.

Real browser preview

[Cropped real Reddit browser preview for an unpublished r/test example]

Maintainer test on 2 November 2026: the form was filled, but no post was sent. Reproduction steps and limits.

Here is an illustrative terminal sequence. Replace placeholders with identifiers returned by the CLI:

bash
reddit-mcp-publisher reddit-preflight testreddit-mcp-publisher prepare reddit-post --subreddit test --title "A tool for reviewing Reddit drafts" --body "I built a self-hosted tool. Feedback welcome."reddit-mcp-publisher preview <draft-id>

After inspecting the preview and deciding to publish:

bash
reddit-mcp-publisher approve <draft-id> --digest <preview-sha256>reddit-mcp-publisher publish <draft-id> --approval <approval-token>

The publisher records publication status and the permalink when Reddit confirms submission. Approval is tied to a specific draft and destination.

Browser MCP vs Reddit API tools

Reddit MCP Publisher operates through an authenticated browser session to handle surfaces such as Reddit Chat, notifications and the live posting composer. An API-based Reddit integration typically uses developer credentials and has a different set of supported endpoints and limits. Both must respect Reddit rules. The project is local/self-hosted: there is no public hosted account connection.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
