Free CLI Agent: Pi + Ollama + Gemma 4 + Parallel Search MCP — $0, No API Keys

Parallel just published a recipe for a fully free, fully local CLI agent: Mario Zechner's Pi harness, Gemma 4 on Ollama, and Parallel's no-key Search MCP. Result: a one-file `brief` CLI that prints a sourced morning-coffee summary on any topic — at $0 in API charges and zero keys in your shell history.
