Reddit Research MCP

What king-of-the-grackles/reddit-research-mcp MCP server does

king-of-the-grackles/reddit-research-mcp exposes Reddit research functions to MCP-compatible AI assistants. It is designed for market research, competitive analysis, customer discovery, product validation, and ongoing monitoring based on public Reddit discussions.

The service indexes more than 20,000 active subreddits and uses semantic search to find communities related to a concept rather than relying only on subreddit names or exact terms. Retrieved findings include links to source posts and comments, along with available engagement details such as upvotes and awards.

Research feeds provide persistent collections of subreddits. A feed can be created, listed, viewed, updated, or deleted, allowing a recurring research configuration to be retained between sessions.

How it works

king-of-the-grackles/reddit-research-mcp is available through the hosted MCP URL https://mcp.dialog.tools/mcp. The server follows a three-stage interaction model:

• discover_operations reports available operations and workflow guidance.
• get_operation_schema exposes parameter requirements, validation information, and optional examples.
• execute_operation runs a selected operation with its validated arguments.

The Reddit operations include semantic subreddit discovery, post search within a subreddit, fetching posts by listing type, concurrent retrieval from multiple subreddits, and retrieval of complete comment trees. Feed operations cover creation, listing, retrieval, modification, and deletion.

Authentication uses Descope OAuth2, with tokens managed by the MCP client. The service does not require Reddit API credentials and accesses public Reddit data. The first authentication step is described as taking about 30 seconds.

Setup and configuration

Connect an MCP client to the hosted endpoint rather than installing Reddit credentials or configuring local secrets. The README provides client-specific commands or links for Claude Code, Cursor, OpenAI Codex CLI, and Gemini CLI. Other assistants can use the direct MCP URL if they support the required MCP transport and authentication flow.

For Claude Code, the documented connection uses an HTTP transport. Codex CLI and Gemini CLI use mcp-remote with an authentication timeout and HTTP access enabled. Cursor has a dedicated installation link. No server environment variables are documented for the hosted setup.

Tools and capabilities

The server advertises three MCP-level tools: operation discovery, operation schema inspection, and operation execution. It also provides one reddit_research MCP prompt and a reddit://server-info resource for documentation.

Within Reddit research, discover_subreddits searches indexed communities semantically, search_subreddit searches posts with time and sort filters, fetch_posts retrieves hot, new, top, or rising posts, fetch_multiple batches retrieval across communities, and fetch_comments returns discussion trees. Feed management stores subreddit selections with related analysis and metadata.

Limitations and notes

The service covers public Reddit data and does not provide access to private communities or non-Reddit sources. Research runs on demand inside the connected assistant; scheduling, cross-source workflows, and delivery to Slack, Telegram, or a web application belong to the separate Dialog platform rather than this standalone server.

The indexed community catalog is described as containing active subreddits with at least 2,000 members and weekly updates. Results are intended to remain verifiable through citations to the underlying Reddit discussions.
