About systemprompt-mcp-reddit
systemprompt-mcp-reddit is an MCP server for AI agents to read Reddit posts, create posts and replies, and manage subreddit settings. It includes configurable writing guidance and rule compliance, and is designed for the systemprompt.io client with sampling and notifications.
Key features
- 01Configure multiple subreddits
- 02Retrieve hot, new, or controversial posts
- 03Create text and link posts and replies
- 04Set writing style and content guidelines
- 05Apply subreddit rules to generated content
Use cases
- 01Review posts from configured subreddits
- 02Draft posts and context-aware replies
- 03Generate content following subreddit requirements
MCP support
The server exposes Reddit operations through MCP tools and uses sampling and notifications. It is designed for the systemprompt.io client and may not work properly with other MCP clients.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Website | Documentation | Blog | Get API Key
A specialized Model Context Protocol (MCP) server that enables AI agents to interact with Reddit, including reading posts, creating content, and managing subreddit configurations. The server is designed to work specifically with systemprompt.io client that support sampling and notification features, and may not function properly with other MCP clients.
An API KEY is required to use this server. This is currently free, although this may change in the future. You can get one here.
This server uses Sampling and Notification functionality from the @modelcontextprotocol/sdk.

System Architecture
This project follows a modular architecture designed to be adaptable for other MCP server implementations:
Core Components
- MCP Protocol Layer: Implements the complete Model Context Protocol
- Service Layer: Abstracts Reddit API interactions
- Handler Layer: Routes and processes MCP requests
- Tool Layer: Defines operations AI agents can perform
- Utility Layer: Provides helpers for validation and data transformation

- TEMPLATE_GUIDE.md: Guide for creating new MCP servers
Using as a Template
This codebase is designed to serve as a template for creating other MCP servers. The modular architecture makes it straightforward to replace the Reddit integration with other APIs:
- Replace the service layer with your API implementation
- Define new tools appropriate for your domain
- Update type definitions and schemas
- Configure server capabilities

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
