Dialog MCP Server

Open source Reddit intelligence, part of the research engine that powers Dialog

Version: 1.0.1

---

Turn Reddit's chaos into evidence-backed insights. This MCP server gives any AI assistant semantic search across 20,000+ active subreddits, deep-dive access to posts and comment threads, and saved feeds for ongoing monitoring. Every finding comes with citations to real posts and comments.

It's fully usable on its own, for free, in Claude Code, Cursor, Codex, Gemini CLI, or any MCP-compatible client. It's also part of the research engine that powers Dialog, the AI agent platform for continuous market intelligence, where it ships connected to every agent.

Why This Server?

Evidence-based insights with full citations. Every finding links back to real Reddit posts and comments with upvote counts, awards, and direct URLs. When you say "users are complaining about X," you'll have the receipts to prove it.

Zero-friction setup. No Reddit API credentials needed. No terminal commands. No credential management. Just connect and start researching.

Semantic search at scale. Reddit's API caps at 250 search results. This server searches conceptually across 20,000+ indexed subreddits using vector embeddings, finding relevant communities you didn't know existed.

Persistent research management. Save subreddit collections into feeds for ongoing monitoring. Perfect for long-term competitive analysis and market research campaigns.

discover_operations()

See what operations are available and get workflow recommendations.

Layer 2: Schema Inspection

get_operation_schema("discover_subreddits", include_examples=True)

Understand parameter requirements, validation rules, and see examples before executing.

Layer 3: Execution

execute_operation("discover_subreddits", {
    "query": "machine learning",
    "limit": 15,
    "min_confidence": 0.6
})

Perform the actual operation with validated parameters.
