Koskamo

fourchan-mcp

An MCP server that allows agents to interact with 4chan's read-only JSON API. It provides tools to list all boards (split into SFW/NSFW), retrieve live threads for a specific board sorted by reply count, and read the posts within a specific thread. The server flattens post HTML into readable text and includes image filenames.
