Reddit MCP Server: Qualified Reddit Leads in Your Agent

Your AI agent can already read your codebase and your database. It can't tell you which Reddit thread from this morning contains a buyer asking for a product like yours. A Reddit MCP server fixes that. This guide shows you how to wire one up in about 5 minutes.

TL;DR: MCP (Model Context Protocol) is the open standard that lets AI agents call external tools, and Grabbit ships a hosted Reddit MCP server at https://mcp.grabbit.sh/mcp. Connect it to Claude or any MCP client and your agent can pull qualified Reddit leads, brand mentions, and keyword matches from your projects, already scored for relevancy.

What a Reddit MCP Server Is

The Model Context Protocol is an open standard, introduced by Anthropic in November 2024, that gives AI assistants a uniform way to connect to external data and tools. No custom glue code per integration. A client like Claude discovers a server's tools at connect time and calls them with structured inputs. The MCP documentation covers the protocol in depth.

A Reddit MCP server is any MCP server whose tools expose Reddit data. Most open-source ones you'll find on GitHub are thin wrappers around the public Reddit API: search posts, read comments. Useful for browsing. But your agent still does all the qualification work on raw posts, and you inherit the API-key setup plus the hosting.

Grabbit's MCP server sits one level higher. Grabbit already monitors your chosen subreddits on a schedule, scrapes new posts, and classifies each one for relevancy against your project description, as covered in why Reddit matters in lead discovery. The MCP server exposes that qualified stream, so your agent queries leads, not noise.

The Tools Grabbit Exposes

Grabbit MCP registers 15 tools under one verb grammar — list_, get_, and search_ for reads, create_, update_, set_, add_, and remove_ for writes. The ones you'll call most:

Keywords and tags get create, update, and pause/resume tools on top — deleting them stays in the dashboard, so an agent can never destroy your setup. Every tool carries read-only, destructive, and idempotent annotations, and responses come back as structured JSON sized for agent context windows. The full reference lives on the MCP server page.

list_project_entries is deliberately generic. Your agent uses analysis filters such as relevancy:high, mention:project, sentiment:negative, or intent:buying instead of calling several preset tools that all perform the same query underneath. Labels from the same category are ORed; different categories are ANDed. Set hideOwnReplies to true to exclude entries authored by social accounts registered by the project owner. The MCP user's identity only authorizes project access; account identities stay private and are not returned in the response.

This is the data those tools sit on top of, as seen in the dashboard: one of our own projects scored 1,947 entries across 5 subreddit feeds in 30 days, and qualified 363 of them.

There's a deliberate gap in that table: no posting and no replying to Reddit itself. That's intentional. Grabbit doesn't automate Reddit engagement, because automated replies are how accounts get banned and brands get roasted. The agent finds threads, checks the subreddit's rules, drafts, and tracks; a human posts.

Connecting It

You need a Grabbit account with a project, then one of two credentials: an OAuth flow for clients that support it, or an API token created in the dashboard under Settings, MCP.

For Claude Code, one command:

claude mcp add --transport http grabbit https://mcp.grabbit.sh/mcp

For clients configured through JSON, the shape is:

{
  "mcpServers": {
    "grabbit": {
      "url": "https://mcp.grabbit.sh/mcp"
    }
  }
}

The server is stateless and speaks streamable HTTP with JSON responses, so there's no session to manage. You can verify it's alive from a terminal; an unauthenticated call answers with a proper JSON-RPC error rather than a timeout:

curl -X POST https://mcp.grabbit.sh/mcp \
  -H "content-type: application/json" \
  -H "accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","method":"initialize","id":1}'
 
{"jsonrpc":"2.0","error":{"code":-32000,"message":"Missing bearer token"},"id":null}

Add -H "Authorization: Bearer <your token>" and the same call succeeds. Rate limit: 60 requests per user per minute, which is generous for agent workloads that batch 3 or 4 tool calls per question.

What to Ask Your Agent

Once connected, the value shows up in plain questions:

• "List this week's leads using relevancy:medium or relevancy:high."
• "Pull buying leads using relevancy:medium, relevancy:high, and intent:buying."
• "Find negative brand mentions using mention:project and sentiment:negative."
• "List today's entries matching these project keyword IDs."
• "Check which of our feeds allow self-promotion before I reply."
• "Mark these three entries as replied and tag them follow-up."

The pattern behind all four: the agent filters and summarizes, Grabbit has already qualified, and you only read what's worth reading. That's the same monitoring-beats-browsing argument from our best subreddits for lead generation guide, extended one step: now the reading happens inside whatever agent you already work in.

The ScrapeGraphAI Reddit insights case study applies this workflow to a fixed 30-day project, including prompts for comparing feeds, retrieving competitor evidence, reading full threads, and checking subreddit rules.

It also composes with other MCP servers. An agent with Grabbit plus your CRM's server can pull this morning's leads and log the promising ones as contacts in one conversation. That composition is the actual promise of MCP, and it's why we shipped a server instead of yet another Zapier recipe.

Where This Fits in the Tool Landscape

If you only need raw Reddit browsing inside an agent, a community Reddit MCP server wired to your own Reddit API credentials can cover eligible free use cases within Reddit's documented limits. Commercial access is different: Reddit directs businesses to a separate agreement and does not publish a standard current rate card. Our Reddit API pricing guide separates the 2026 rules from the old 2023 per-call figure. The shutdown of GummySearch, covered in our GummySearch alternatives comparison, shows why that distinction matters.

Grabbit's MCP server is the managed end of that spectrum. Scraping through rotating proxies, deduplication, AI relevancy scoring, and mention detection all happen server-side, and the MCP layer gives your agent the whole workflow on top: find, qualify, read, draft, and track — everything except pressing the reply button on Reddit, which stays yours.

Conclusion

A Reddit MCP server puts Reddit into your agent's toolbox; Grabbit's puts qualified leads there. 15 tools across the whole lead workflow. OAuth or token auth. One stateless endpoint at https://mcp.grabbit.sh/mcp, and no spam automation by design.
