Show HN: Antenna – RSS reader with a built-in MCP server

4 hours ago

Antenna is a local RSS feed manager that stores subscriptions in a SQLite database, eliminating dependency on cloud vendors and proprietary lock-in.
It provides two primary outputs: clean HTML emails sent via user's own SMTP (with features like per-post/digest modes and deduplication) and integration with AI agents via MCP protocol, offering tools for feed management and search.
The tool emphasizes data ownership, with all subscription graphs controlled by the user, and includes future plans for hosted multi-user services and HTTP MCP surface.
