Why Synapse MCP?
100% Local-First
All state lives in .synapse/brain.db. Zero cloud dependencies, zero external network sockets, zero telemetry.
Anti-Collision Locks
File locks prevent race conditions when multiple agents edit the same repository simultaneously.
Shared Architecture Memory
Architectural Decision Records (ADRs) persist across agents so established conventions are never reverted.
Investigation Unknowns
Agents flag unanswered questions or unexpected bugs for peer agents to investigate and resolve.
Supported AI Clients
Automatic one-command setup for all major coding assistants.
