modrinth-mcp

An MCP server that allows agents to search the Modrinth platform and manage Minecraft mod projects. It supports reading project metadata, listing versions, creating new projects as drafts, and uploading new versions with jar files. It interacts with the Modrinth API, requiring a Personal Access Token for write operations.
