Broll: MCP server for coding agents to create and publish marketing content

Broll is an MCP server that gives coding agents (Claude Code, Codex) a content studio to generate images, videos, carousels, and publish to Bluesky/Mastodon. It uses LLMs to draft content and automate marketing workflows, solving the problem of indie developers needing to create and publish marketing material without manual effort.

Notable capabilities: generate images/video with user's own API keys, compile declarative JSON plans into ffmpeg renders (captions, music, aspect ratios), render branded carousels with code-defined layouts, publish to Bluesky/Mastodon with draft-first approval. Tech stack: MCP server, ffmpeg, BYO-key generation. Traction: open-sourced (MIT), ~100 tests, honest README. The agent built most of the product, designed its logo, and runs launch content on Bluesky (@brollapp.bsky.social).
