Named pipes beat HTTP latency for local agentic tools while keeping in-memory state between calls.

Strengths

•Persistent servers hold model weights and indexes in memory instead of reloading per-call.
•cpipe CLI utility enables ad-hoc commands to any running pipe server from terminal.
•Claude Code skill teaches agents to discover and query running pipe servers automatically.

Weaknesses

•Unix-only limits audience; no Windows named pipe equivalent implementation.
•Agentic tools category is emerging with unclear long-term adoption patterns.

Post Description

I've created an alternative to CLI and MCP for locally running agentic tools. It uses Unix-based OS's named pipes, which means the client has quick IPC with the tool and it can have in-memory state. I created it to build components for voice agents (TTS, STT, LLM chat) but it has wide range of uses! Comes with a CLI tool, cpipe (like curl), and a Claude Code skill
