README

FerryCat: Contract-Driven Cross-Host AI Agent Handoff Bus

English • 中文

FerryCat (ferrycat) is a lightweight, deterministic cross-host AI agent handoff and code review bus built on the Model Context Protocol (MCP) and Node.js built-in node:sqlite (WAL mode).
Purpose-built to safely bridge isolated desktop IDE agent hosts (such as Google Antigravity, WorkBuddy, Claude Code, and Cursor) across separate OS processes without context drift or blind reviews on stale files.

📖 Deep Dive: Why I Started Building FerryCat: When Two AI Coding Hosts Live on the Same Desktop

Core Pain Points & Engineering Solutions

While the official MCP Tasks specification (2025-11 / 2026-07) addresses long-running operations within a single Client ↔ Server connection, it does not solve cross-host collaboration on a developer workstation:

stdio Process Isolation: Desktop IDEs spawn local MCP servers as independent child processes with isolated memory spaces and distinct Node.js runtimes.
Silent Blind Reviews on Stale Code (Stale Context): When handing off a task from Host A to Host B, unushed IDE buffers, branch switches, or mid-review edits cause the receiving agent to audit outdated code and produce plausible but invalid conclusions.
Context Window Bloat: Pasting hundreds of lines of source code across chat windows duplicates token consumption on both ends.
Unstructured Handoff Outputs: Free-form prose responses lack deterministic schema enforcement, making downstream consumption unreliable and prone to infinite retry loops.

FerryCat resolves these failure modes through a human-scheduled, contract-driven SQLite WAL bus:
