Runs zshot as a Model Context Protocol server over stdio. zshot reads MCP JSON-RPC from stdin, writes responses to stdout, and sends all logging to stderr. It serves MCP clients such as Claude Code that launch a local server process and talk to it over stdio.

This conflicts with --server; use one or the other. To expose MCP over HTTP from a running server instead, leave the /mcp endpoint enabled. See MCP for client setup.
