The nervous system for AI agents

276 tests, 20 tools/instance

Multi-agent coordination server using the Model Context Protocol — one codebase powering two AI agent instances (Nara at home, Arya at office). 20 tools per instance: shared logging, task management, health diagnostics, automated handoff between agents, and scheduled autopilot playbooks.

Challenge

Two AI agents (home + office) operating in silos — no shared memory, no coordination, no way to hand off context between them. Each restart wiped everything.

Approach

Built an MCP server as the shared nervous system. One codebase, multi-registration. SHA256 dedup middleware prevents log spam. Autopilot playbooks (heartbeat, stale-task cleanup, handoff) run on schedule without human intervention.

Result

276 tests passing. Agents coordinate seamlessly — Nara (home) and Arya (office) share logs, tasks, and context. Automated handoff works across sessions. The foundation for every AI integration in the ecosystem.
