systemprompt-mcp-reddit

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.
