Module mcp 

Model Context Protocol server (stdio transport). Owner: mcp agent.

Runs rss mcp: exposes the same core operations as MCP tools so agents can call the tool directly. Implement with rmcp 1.7 (#[tool] / #[tool_router] macros, serve(stdio())).

Requirements

• Expose tools that delegate to crate::core (do not reimplement fetch/parse):
  • fetch_feed { url, content_format?, limit?, since? } → a single feed’s FeedResult (or the full FetchOutput for multiple urls).
  • discover_feeds { site_url } → DiscoverOutput.
  • get_item { feed_url, id } → one Item (fetch + find by stable id).
  • get_schema { command } → the JSON Schema from crate::output::schema_for.
• Tool results are JSON (serialize the model types).
• All logging/diagnostics must go to stderr — stdout is the MCP transport.
• Build the Cache once and share it across tool calls.

Functions

serve_stdio

Run the MCP server over stdio until the client disconnects. Owner: mcp agent.
