How to Find Leads With Hermes Agent Reddit Monitoring and the RedReplier Plugin

Setting up Hermes Agent Reddit lead finding takes two terminal commands and one browser sign-in with the RedReplier plugin from the Hermes plugin catalog. After that, Hermes reads the mentions RedReplier has already matched to your keywords and scored for relevance, so you ask "any new leads?" and get the five threads worth answering instead of five hundred.

Hermes Agent, the agent from Nous Research, runs in your terminal and can run scheduled cron tasks. What it lacks is a way to watch Reddit for the people asking for a tool like yours. Browsing subreddits one page at a time is slow, and it gives the agent no memory of which threads you already dealt with. RedReplier does the watching. It matches your keywords on Reddit, Hacker News, X, Bluesky and Facebook, scores every mention from 0 to 100 against your product description, and keeps a status on each one. Hermes reads that list.

The short version: add your website and keywords at redreplier.com, run hermes plugins install redreplier and hermes plugins enable redreplier, start a new Hermes session and sign in when the browser opens. Then ask Hermes for this week's best leads with a score of 70 and above. Hermes asks for your approval before it adds keywords, triages mentions or changes alerts, and it never posts a reply for you.

What is the RedReplier plugin for Hermes Agent?

The RedReplier plugin is an entry in the Hermes plugin catalog, listed in the Hermes Marketplace, that connects Hermes Agent to the RedReplier MCP server at https://mcp.redreplier.com/mcp. The package holds a plugin.json manifest, an mcp.json server config and one skill that teaches Hermes how to find and triage leads. It ships no code of its own.

The server is the same one Claude Code, Claude Desktop, ChatGPT and Cursor use, so a mention you approve in Hermes shows as approved in the RedReplier dashboard and in every other client. RedReplier lists the Hermes plugin on its AI agents page and on the AI Agents tab of the API Tokens page in the app.

Hermes never logs in to Reddit or any other network. RedReplier does the matching and scoring on its side, and Hermes reads the results.

What do you need before you install it?

You need Hermes Agent 0.21.6 or newer, Node.js 20.18.1 or newer with npx on your PATH, and a RedReplier account with at least one website and its keywords added. Your RedReplier plan has to include API access, because every tool call answers subscription_required without it. Any workspace role can read mentions, and changes need the Admin or Editor role.

The Node.js requirement is the one people miss. The plugin runs a small sign-in bridge, mcp-remote, through npx, so a Hermes install with no Node on the machine fails at the sign-in step.

Add the website first. RedReplier scores each mention against the website's description, and a website with no description gets unscored mentions, which leaves Hermes nothing to rank by.

How do you install the RedReplier plugin in Hermes Agent?

You install RedReplier by name from the Hermes plugin catalog and sign in once in your browser:

1. Run hermes plugins install redreplier. Hermes shows the entry's capability summary before it clones anything, then checks out the exact commit the catalog reviewed.
2. Run hermes plugins enable redreplier. Installing puts the plugin on disk, and enabling is what makes Hermes load it. In a terminal, the install step also asks "Enable now?", so answering yes covers both.
3. Start a new Hermes session. The first time the server starts, your browser opens the RedReplier sign-in page.
4. Sign in with the email you use on RedReplier and approve access.
5. Ask Hermes: "List my monitored websites and their keywords."

hermes plugins install redreplier
hermes plugins enable redreplier

The token is kept and refreshed, so you sign in once. If the tools do not show up after you sign in, run /reload-mcp in the session.

You can also install straight from GitHub with hermes plugins install RedReplier/claude-plugin --no-enable, then hermes plugins enable redreplier. I would pick the catalog route, because it installs the commit a reviewer read.

What does the plugin install on your machine?

The RedReplier plugin installs a config, not a program. mcp.json runs the pinned mcp-remote@0.1.49 through npx, which downloads it from npm on first use, opens a local callback port for the sign-in and stores the OAuth tokens in ~/.mcp-auth. The package sends no telemetry and reads nothing from your environment or config files.

The catalog pins a 40-character commit, and installs check out that pin rather than a branch tip. The pin does not cover the tool list. RedReplier's server decides the tool set at runtime, so a new tool on the server reaches Hermes without a new catalog review. The listing says so in its disclosure, and so does the plugin's README.

What can Hermes Agent do with Reddit leads through RedReplier?

Hermes Agent gets 19 RedReplier tools through the plugin, covering workspaces, monitored websites, keywords, mentions and email alerts. Mentions come from Reddit posts and comments, Hacker News, X, Bluesky, Facebook posts and Facebook groups. Here is what that looks like by job:

• Find leads. list_mentions filters by status, score, keyword, source and date and sorts by relevance or recency. count_mentions returns only the total, which is the cheap way to ask "how many this week?".
• Explain a score. explain_mention returns why a mention scored the way it did, a set of tags and a drafted reply. It is slow, so the skill tells Hermes to run it on the few leads worth acting on, not on a whole list.
• Triage. update_mention_status marks a mention approved, rejected or back to new. Any status can move to any other, so nothing is final.
• Websites. List, read, add, rename, describe and delete monitored websites, and have analyze_website write a description from the site's public pages.
• Keywords. Add, reword, disable, re-enable and delete keywords. Keywords past your plan's limit wait as pending, and adding one never charges.
• Alerts. Read and change the email digest cadence. Valid cadences run from 15 to 1,440 minutes, and your plan sets the fastest one you can pick.

Two defaults hide rows from list_mentions. Rejected mentions stay out unless Hermes asks for them, and mentions under the website's minimum score, 30 unless you changed it, stay out unless Hermes sets includeLowRelevance. If a mention you saw in the dashboard is missing from Hermes, one of those two is the reason.

Slack, Telegram, Notion and Linear alerts are set up in the RedReplier app, not through the plugin. The Reddit lead generation page covers what RedReplier does for leads without an agent.

Which RedReplier tools does Hermes ask about first?

Hermes Agent asks for your approval before every RedReplier tool that the server does not mark read-only, because the plugin's plugin.json marks the server untrusted. That covers adding, changing or deleting websites and keywords, approving or rejecting mentions, explaining a mention's score and changing alert settings. Reading websites, mentions, counts and alert settings runs without a prompt.

Hermes also refuses those tools in cron jobs and other unattended runs. That includes explain_mention, which RedReplier marks as a write because the first call generates the reason and the drafted reply. A morning cron job can count and list your new leads. It cannot explain them, approve them or reject them with nobody watching. I think that is the right split. An agent that quietly rejects mentions overnight leaves you with a tidy inbox and no idea what it threw away.

One read-only tool does more than read. list_websites also turns pending keywords that fit your plan into active ones and queues their searches. It never charges, and it never touches a keyword your plan has no room for.

Your workspace role is the second limit, because Hermes acts as you. Every change needs the redreplier.write permission, which Admin and Editor hold.

What prompts can you try first?

These prompts come from the plugin's own README. Under each is what Hermes does in RedReplier.

"Show me this week's best leads, score 70 and above"

Hermes calls list_mentions with new mentions only, a minimum score of 70 and a date filter for the week, sorted by relevance. It shows one short block per lead: network and subreddit, title, score, one line on why it is a lead, and the link. This is a read, so it runs without a prompt.

"Why did this Reddit thread score 85? Draft a reply I can post"

Hermes asks before it runs explain_mention, then shows the reason behind the score and a reply draft. The skill tells Hermes to answer the thread's question first, mention your product once with a disclosure line and leave links out unless the thread asks for tools. You paste the reply on Reddit yourself.

"Add 'social media scheduler' and 'buffer alternative' as keywords for my website"

Hermes asks before it calls add_keywords, then reports each keyword with its status. Keywords that fit your plan go active. The rest wait as pending, and Hermes says which.

"Approve the top three mentions and reject the rest"

Hermes reads the mentions first, because the skill tells it never to approve a mention it has not read, then asks before each status change. A wrong call is one more prompt to undo.

"How many Hacker News mentions did we get this month?"

Hermes calls count_mentions with the Hacker News source and a date filter and gives you one number. No prompt.

"Send me an email digest every 4 hours"

Hermes reads your alert settings, then asks before it sets the cadence to 240 minutes. If your plan's fastest cadence is slower than that, RedReplier raises the value to the plan's floor.

How do you run Hermes Agent headless with an API key?

On a server or any machine without a browser, skip the plugin and add the RedReplier MCP server to ~/.hermes/config.yaml with an API key. The OAuth sign-in needs a browser window, and a headless box has none.

mcp_servers:
  redreplier:
    url: 'https://mcp.redreplier.com/mcp'
    headers:
      Authorization: 'Bearer ${REDREPLIER_API_KEY}'

Create the key on the API Tokens page and put REDREPLIER_API_KEY=... in ~/.hermes/.env. Keys start with redreplier_, need a plan of $10 per month or more, and work like a password for your RedReplier account, so keep them out of chats. The MCP server docs cover how keys and roles work.

This route skips the plugin, so it also skips the plugin's skill and the untrusted setting in its plugin.json. A RedReplier key acts with the role of the member who created it, so a key made by a Viewer reads mentions and scores but can't change anything. Use one when a headless agent should only read. Tell a headless agent in its instructions which tools it may call, and leave delete_keyword off the list, because it erases the keyword and every mention it found.

When should you use Claude Code, Zapier or n8n instead?

Use Hermes when you already work in it. The same plugin installs in Claude Code with /plugin install redreplier --marketplace RedReplier/claude-plugin, and Claude Desktop, ChatGPT, Cursor, Windsurf, VS Code, Codex and Gemini CLI connect to the same server URL. The setup for each client is in the RedReplier agent repo, and the AI agents page shows what the agent can do.

If you want leads to land somewhere without a conversation, use an automation tool. The Zapier Reddit guide sends scored mentions to Slack, Discord or a sheet, and the n8n Reddit guide does the same with the RedReplier community node. For agents that run on their own computer, the Manus Cue connector for social listening and the Grok bot template for lead finding cover the setup and the limits to write into the brief.

If you want to watch Reddit without any agent at all, Reddit keyword monitoring in the RedReplier dashboard reads the same mentions.

Frequently Asked Questions

Can Hermes Agent monitor Reddit?

Hermes Agent monitors Reddit through the RedReplier plugin from the Hermes plugin catalog. Install it with hermes plugins install redreplier, enable it and sign in with your RedReplier account. Hermes then lists and counts the Reddit posts and comments that match your keywords, scored 0 to 100, along with mentions from Hacker News, X, Bluesky and Facebook.

Do I need an API key to use RedReplier in Hermes Agent?

The RedReplier plugin for Hermes Agent needs no API key. It signs in with OAuth in your browser the first time the server starts and keeps the token refreshed. You need an API key only for a headless setup, where you add the server to ~/.hermes/config.yaml with a key from the API Tokens page.

Which Hermes Agent version does the RedReplier plugin need?

The RedReplier plugin needs Hermes Agent 0.21.6 or newer and Node.js 20.18.1 or newer with npx on your PATH. Node.js runs mcp-remote, the bridge that handles the sign-in and talks to the RedReplier MCP server.

Can Hermes Agent post replies on Reddit through RedReplier?

Hermes Agent cannot post replies through RedReplier, because RedReplier has no tool that publishes anything. explain_mention drafts a reply, and you paste it on Reddit, Hacker News, X, Bluesky or Facebook yourself. After you post, Hermes can mark the mention approved.

Will Hermes Agent change my keywords without asking?

Hermes Agent asks before every RedReplier tool that changes something, because the plugin marks the server untrusted. Adding, editing, disabling and deleting keywords, triaging mentions, explaining a score and changing alerts all wait for your yes, and Hermes refuses them in cron and other unattended runs.

Can a Hermes cron job check for new Reddit leads?

A Hermes cron job can list and count new RedReplier mentions, because those tools are read-only. It cannot run explain_mention, approve or reject mentions, or change keywords, since Hermes refuses write tools from an untrusted server in unattended runs. Do those steps in a live session.

Which sources does the RedReplier plugin watch?

The RedReplier plugin returns mentions from Reddit posts, Reddit comments, Hacker News, X, Bluesky, Facebook posts and Facebook groups. Each mention carries its source, so Hermes can filter to one network or count per network.

Will adding keywords from Hermes charge me?

Adding keywords from Hermes never charges. Keywords that fit your RedReplier plan go active, and the rest wait as pending until you free a slot or upgrade in the RedReplier app. No RedReplier tool changes your subscription.

Where does the plugin store my RedReplier sign-in?

The RedReplier plugin stores its OAuth tokens in ~/.mcp-auth on your machine. The mcp-remote bridge writes them there after you sign in and refreshes them, so you sign in once. The package sends no telemetry.

Why don't the RedReplier tools show up in Hermes after I sign in?

Run /reload-mcp in the Hermes session if the RedReplier tools are missing after the browser sign-in. Also check that the plugin is enabled, since hermes plugins install puts it on disk and hermes plugins enable redreplier makes Hermes load it.
